Episode 7: Mexican Sage BushMexican Sage Bush

Common Name: Mexican Sage Bush

Scientific Name: Salvia leucantha   ‘Santa Barbara’

Plant Description: Mexican bush sage is a bushy evergreen subshrub in frostfree climes, and a returning perennial where it gets frosted back in winter. It grows in a loose, spreading mound up to 2-4 ft (0.6-1.2 m) tall and about the same width. The leaves are lance shaped, like willow leaves, 1-5 in (2.5-12.7 cm) long, puckery on top and white-wooly underneath. They are on petioles about an inch long and arranged in opposite pairs along the squarish stems. The young, fast growing stems are thick and conspicuously white-wooly. From autumn throughout winter (or until the first frost) Mexican bush sage blooms with white flowers 1-2 (2.5-5 cm) long that extend from velvety purple or lavender-blue calyces. The bicolored inflorescences are borne in very showy elongated arching clusters 6-12 (15-30.5 cm) in length at the ends of erect, spreading stems. At any given time, there will be just a few actual flowers per cluster, but lots of pretty purple calyces. These inflorescences are profuse and extend way beyond the foliage, making this one of the most attractive of the salvias. Some cultivars of Mexican bush sage (for example, 'Midnight' and 'Purple Velvet') have flowers the same color as the purple calyces.

Plant Profile & Needs:

  • Plant Type: Spreading subshrub
  • Origin: Mexico
  • Zones: 9 - 10
  • Height: 2'-3'
  • Rate of Growth: Fast

  • Soil Requirements: Well-drained soil
  • Water Requirements: Drought tolerant
  • Nutritional Requirements: Balanced liquid fertilizer monthly
  • Light Requirements: Full sun
  • Form: Arching subshrub
  • Leaves: 2"-6" linear lanceolate, aromatic; pinch young plants to promote fullness
  • Flowers: Long, slender spikes of lavender or white flowers, cut out old stems after flowering
  • Fruits: None
  • Pests: Few
  • Uses: Border shrub

Planting Notes: Mexican bush sage is easy to propagate from root cuttings and stems that have rooted where they touch the ground. Ordinary stem cuttings can also be rooted.

Episode 8: Ornamental PepperOrnamental Pepper

Common Name: Ornamental Pepper

Scientific Name: Capsicum annuum 'Chilly Chili'  and Capsicum annuum 'Explosive Ember'

Plant Description: The Chilly Chili is an All American Selection Winner . The plant produces high yields of 2" long hot peppers. Peppers grow upright and turn from greenish yellow, to orange, to red when mature. A beautiful plant suitable for indoor pots.There are about 23 species of chile peppers (genus Capsicum), but nearly all of the cultivated varieties belong to one of just four or five species. All of the peppers are perennial semi-woody sub-shrubs, although they usually are cultivated as annuals. They are mainly glabrous (without pubescence), much branched, 2-4 ft (0.6-1.2 m) tall, with alternate leaves and modest little flowers which give rise to colorful fruits.

Plant Profile & Needs:

  • Peppers are grown much like tomatoes.
  • Light: Full sun.
  • Moisture: Peppers will produce best when supplied with adequate water. They are not particularly drought tolerant. If the soil is well drained they thrive best when it rains every day.
  • Hardiness: Although they are perennial, peppers (except for rocotos) are usually grown as annuals, even in tropical climates. Mature plants can tolerate a touch of frost.

Episode 9: Dwarf GoldenrodDwarf Goldenrod

Common Name: Dwarf Goldenrod

Scientific Name: Solidago ‘Baby Gold’

Plant Description: Goldenrod is an excellent garden perennial that often gets accused of causing hay fever. It is actually ragweed that is the cause and not goldenrod. Goldenrod is a vigorous late summer to early fall flowering plant. Goldenrod grows well in full sun to very light shade in well drained soil of average fertility.

Plant Profile & Needs:

  • Height: 18" to 24"
  • Spread: 10" to 20"
  • Flower color: Yellow-gold
  • Bloom time: Autumn

 Episode 10: Miss Huff (Lantana)Miss Huff

Common Name: Miss Huff

Scientific Name: Lantana camara ‘Miss Huff’

Plant Description: This selection of lantana was introduced by Goodness Grows Nursery in Georgia, from, whom else... Miss Huff of nearby Athens.  The plants emerge from the ground in early May and within a couple of weeks are topped with showy orange and pink flower heads that are produced nonstop until frost. Virtual sterility also prevents unwanted seedlings and promotes more flowering. Established clumps will get quite large (to 10' spread) when happy! It attracts butterflies like magnets, while the pungent foliage repels deer. Drought tolerance is another outstanding feature that should not be overlooked.

Plant Profile & Needs:

  • Growth Height: 36 - 60"
  • Recommended Zone: 7 - 11
  • Growing Characteristics: full sun, mounded form 3 to 5 feet tall, deer resistant

Planting Notes: For full hardiness, establish well prior to winter. Do not cut old stems in fall or winter when grown in marginal climates. A complete, balanced fertilizer such as 10-10-10 or 13-13-13 applied at 1 pound per 100 square feet at planting time and when new shoots emerge in the spring will provide adequate nutrition in most situations. Although it's tempting to prune back the old foliage soon after fall frost singes the foliage, cold hardiness increases when pruning is delayed until early spring, just as new growth begins.

Episode 11: Acoma Crape MyrtleCrape Myrtle

Common Name: Acoma Crape Myrtle

Scientific Name: Lagerstroemia ‘Acoma’

Plant Description: A long period of striking summer flower color, attractive fall foliage, and good drought-tolerance all combine to make `Acoma' Crape-Myrtle a favorite small tree for either formal or informal landscapes. It is highly recommended for planting in urban and suburban areas and has good resistance to powdery mildew. This crape myrtle cultivar (a cross between L. indica and L. fauriei) is one of several mildew resistant hybrids developed by the National Arboretum in Washington, D.C., all of which have been given Native American tribe names. It is a deciduous, upright, spreading, multi-stemmed shrub. Features dark green foliage turning dull red to reddish purple in fall, gray bark which exfoliates with age and terminal, crepe-papery, 6-7" long inflorescences (panicles) of white flowers from mid-summer to early fall. Flowers give way to round seed capsules which often persist well into winter. In the South, this cultivar can easily be grown as a woody shrub with a maximum size of 10' tall and 11' wide.

Plant Profile & Needs:

  • Height: 10 to 15 feet
  • Spread: 6 to 10 feet

Episode 13: Goshiki OsmanthusGoshiki Osmanthus

Common Name: Goshiki Osmanthus

Scientific Name: Osmanthus heterophyllus ‘Goshiki’

Plant Description: Don't be fooled into thinking this is a variegated English holly. Yes, its leaves are spiny, but Osmanthus heterophyllus 'Goshiki' does not seed around and grows to only 4 feet high at most (a little wider). A telltale sign: Osmanthus has leaves arranged in opposite pairs; the leaves of holly are alternate. The leaves of 'Goshiki' are streaked with cream, and new growth has a pink tone to it. 'Goshiki' makes a fine container plant or garden component. It will maintain its good looks throughout the seasons, while deciduous partners and herbaceous plants come and go. It has an upright growth habit, so you can judiciously prune off one stem at a time to lower its height (prune off at a junction with another, larger stem). Grow 'Goshiki' in full sun or part shade.

Plant Profile & Needs:

  • Position: full sun or partial shade
  • Soil: fertile, well-drained soil
  • Rate of growth: slow
  • Flowering period: July to September
  • Flower color: white

  • Goes well with: Myrtus communis, Choisya ternata 'Aztec Pearl', Deutzia x magnifica, Sarcococca confusa, Clematis viticella 'Purpurea Plena Elegans', Galanthus nivalis.

Care: Minimal pruning is required. Remove misplaced, dead or diseased branches in late spring and apply a generous 5-7cm (2-3in) mulch of well-rotted garden compost or manure around the base of the plant.

Episode 14: Autumn Ruby Encore AzaleaAzalea

Common Name: Autumn Ruby Encore Azalea

Scientific Name: Rhododendron x Encore ‘Autumn Ruby’

Plant Description:

  • Autumn Ruby is superb in formal gardens and small hedges. It has attractive foliage on a small shrub.
  • Mature Size: 3 1/2' HT x 3' SPD
  • Bloom: 1.75"-2", red blooms
  • The Encore Azalea™ is similar to traditional azaleas in that it requires proper planting, watering, and care to thrive in its new home. The following guidelines will help to ensure that your new plant grows to its full potential.

GROUND PREPARATION: Dig a hole 6-8 inches deep and fill it with water. If the hole drains within a few hours, you have good drainage. If the water is still standing 12 hours later, check the drainage in your yard, you may have to take corrective actions.

PLANTING: Turn the soil well and dig a hole twice as wide as it is deep. Add organic material, such as compost or peat moss, to the soil. Remove the azalea from its container and loosen the root ball. Set the plant into your prepared hole, making sure the top of the root ball is above the soil level. Pull your soil around the plant, water in firmly and cover with mulch.

SPRING/SUMMER PLANTING CARE: Water the azalea well when you first plant it and keep the soil moist until winter. New azaleas will die quickly when the soil dries excessively. Your new azalea should not need regular watering after the first year unless there are periods of drought. Fertilize with the recommended levels of azalea feed soon after planting. Do not fertilize in the fall.

FALL/WINTER PLANTING CARE: Azaleas do well when they are planted at this time. New roots produced in the fall will help the azalea flourish in the next growing season. Although less watering is necessary, do not allow the roots to become dry. Your azalea should not need watering after the first year unless there are periods of drought. Cover your young azalea with insulating covering when extreme cold weather approaches. As your Encore Azalea™ matures, it will need less winter care. Do not fertilize until after the last frost. Once the danger of frost has passed, use azalea feed as directed.

PRUNING: If you think that your Encore Azalea™ needs pruning, do so immediately after spring flowering for maximum bud set.

Episode 15: Autumn SageAutumn Sage

Common Name: Autumn Sage

Scientific Name: Salvia greggii

Plant Description: Autumn sage forms a nice mounding shrub up to 4 feet tall by 2 feet wide. Most of the branches originate near the base of the plant, giving a vase-shaped appearance. Many flower colors are available, although shades of red, pink and white are the most common. The leaves are leathery and small, adaptations that probably help prevent moisture loss. Autumn sage is usually evergreen, but a hard freeze may cause it to die to the ground, usually to reemerge in spring.

Culture

  • Light: Full sun to part shade; can take extreme sun and heat.
  • Moisture: Autumn sage is very drought tolerant. It can take prolonged dry periods once established. Autumn sage requires well-drained soil.
  • Hardiness: USDA Zones 7 - 9.
  • Propagation: Cuttings; may self-seed in mild climates


Usage: Autumn sage is good as an evergreen medium-size shrub.

Features: S. greggii is a very useful landscape plant and is especially well adapted to hot, desert-like areas. It has a long period of bloom. This Salvia also provides winter interest, due to its evergreen habit. Regular pruning is suggested, since these plants can get woody and spindly.

Episode 16: Holiday CactusHoliday Cactus

Common Name: Holiday Cactus

Scientific Name: Shlumbergera truncata

Plant Description: While the poinsettia remains the most popular of the holiday plants, a healthy Holiday cactus in full bloom is a great gift idea for that special gardener. They are easy to care for and can be grown indoors throughout the year. The flowers range in color from yellow, salmon, pink, fuchsia and white or combinations of those colors.

Plant Profile & Needs

  • Recommended Temperature Zone:
  • USDA: 10-12
  • Frost Tolerance: Avoid frost
  • Minimum Avg. Temperature: 55°F (12°C)
  • Sun Exposure: Light shade
  • Origin: Brazil (Rio de Janeiro)
  • Growth Habits: Epiphytic, occasionally lithophytic, cactus
  • Watering Needs: Keep the soil moist
  • Propagation: Cuttings in spring


Planting Notes

  • Light ~ While the Holiday cactus can adapt to low light, more abundant blooms are produced on plants that have been exposed to high light intensity. Keep your plants in a sunny location indoors. Plants can be moved outdoors in summer, but keep them in a shady or semi-shady location. Too much direct sunlight can burn the leaves. When it's time to bring the plants back inside in the fall, slowly adjust the plants to life indoors by gradually increasing the number of hours they spend indoors each day. If you want to grow it indoors in a south or west window, you should shade the plant with glass curtains. No diffusion of light is needed on the north or east. Many growers move the plants to the broken shade of a porch or patio or plunge the pot in a shady spot in the garden during the summer months. Holiday cactus needs shading from the sun between May and September.
  • Soil ~ Well-drained soil is a must for Holiday cactus. Use a commercially packaged potting mix for succulent plants or mix your own. The ideal soil for Holiday cactus is composed of equal parts of garden loam, leaf mold and clean coarse sand (not sand from the seashore). Add a quart of wood ashes per bushel of mixture. One-tenth part by bulk of old dry cow manure may be added if garden soil is poor.
  • Water ~ The plant is not a true cactus and is not quite as drought tolerant as the name infers. However, it is a succulent plant and can store a reasonable quantity of water in the leaves. Water thoroughly when the top half of the soil in the pot feels dry to the touch. The length of time between waterings will vary with the air temperature, amount of light, rate of growth and relative humidity. During the summer, water so that the soil is continually moist. When fall arrives, water the plant only well enough to prevent wilting.

Episode 17: Diane Witch HazelWitch Hazel

Common Name: Diane Witch Hazel, Jelena Witch Hazel

Scientific Name: Hamamelis intermedia ‘Diane’, Hamamelis intermedia ‘Jelena’

Plant Description: Very few things demonstrate the ending of Winter as well as the flowers and fragrance of Witch Hazel (Hamamelis). These small deciduous trees or woody shrubs are renowned for their attractive yellow, orange or red, wispy, scented, flowers that bloom on bare branches in Mid to Late Winter or Early Spring. While all are fragrant to some degree, some feature stronger fragrances than others. Some cultivars are also regarded for their attractive Fall foliage. While there are several different species in the genus, the most common garden varieties are hybrids between the Chinese Witch Hazel, Hamamelis mollis and Japanese Witch Hazel, Hamamelis japonica, and are known as Hybrid Witch Hazels or Hamamelis x intermedia.

Plant Profile & Needs: Witch Hazels perform best in moist, but well drained acidic soil. They do not grow well in heavy, wet or compact soil. Use mulch to cool roots, preserve moisture and assist in the plants growth. Avoid drought as it may stress or damage the plant. Although they will tolerate partial sunshine, Witch Hazels will flower better in Full Sun. If pruning is required, do so after flowering but before the Summer as to avoid damaging the growth of next years flower buds. Witch Hazels make a tasty treat for deer so keep them protected. Most Witch Hazels are hardy in zones 5-9 but many cultivars require a decent cold spell before they will be able to produce flowers.

Episode 18: Diane Witch Hazel & Cabbage/KaleCabbage/Kale

Common Name: Ornamental Cabbage and Kale, Jelena Witch Hazel

Scientific Name: Brassica oleracea

Plant Description: There is a renewed interest in growing ornamental or flowering cabbage and kale. Beautiful in a garden, these plants are very showy in a variety of colors, from white through pink or red, with a leaved center and green outer leaves. Identified by a number of names, such as floral kale, decorative kale, ornamental-leaved kale, and flower kale, ornamental cabbage and kale belong to the Brassica oleracca Acephala Group.The culture of flowering kale is similar to that of kale, as both are commonly grown as a fall crop in the north. The seeds can be planted outdoors in early summer, and can also be grown in containers. They are often planted singly or in beds or groups, and can be transported for ornamental purposes. Plants grow to about one foot in diameter and about 15 in. tall (depending on the time of planting). As their root system is not too extensive, plants can sometimes be dug up and potted in 8 to 10 in. pots to be used for decoration. They will last much longer indoors if placed in cool, brightly lit locations. Individual plants can also be cut off and used in floral decorations if desired.Most authorities indicate that the leaves can be eaten, cooked or raw, but there is occasional disagreement; some say they could cause vomiting and diarrhea if eaten raw in large quantity by small children. The roots of the plant are most dangerous and should not be eaten.

Plant Uses: The plants have unlimited use in the landscape. They are attractive in borders or can be used very effectively grouped in plantings of three, five, or more plants. They are good plants to use in containers for the deck or patio and for window boxes. They are especially good to use to replace warm season annuals for a fall or early winter display. Ornamental cabbage and kale usually grow about eight to eighteen inches high and twelve inches or more across. For best displays, plants should be set about twelve to fifteen inches apart. Unlike most annuals and perennials, cabbage and kale improve in appearance after a frost or two. Leaf color usually intensifies after a light fall frost. They are usually attractive in the garden until Thanksgiving or later. Hint – when the plants smell like cooked cabbage, it is time to pull them out!

Episode 20: Dawn RedwoodDawn Redwood

Common Name: Dawn Redwood

Scientific Name: Metasequoia glyptostroboides

Plant Description:

      The Story of the Dawn Redwood

An excellent description of the discovery of Metasequoia glyptostroboides by scientists in the 1940s is in, A Reunion of Trees, by Stephen A. Spongberg, Harvard Univ. Press, 1990.

Briefly, in 1941 Shigeru Miki, a Japanese paleobotanist, established a new genus, Metasequoia, to accommodate Pliocene fossils from deposits about five million years old. The fossils had previously been confused with Taxodium (bald cypress) and Sequoia (redwoods). Also in 1941, a Chinese forester chanced upon a strange deciduous, coniferous tree near a remote village in eastern Szechwan Province. In 1944 a few leafy branches from the trees and some cones picked from the ground were passed on to a botanist, W. C. Cheng, at the National Central University. He thought the plant samples might be from the Chinese swamp cypress (Glyptostrobus lineatus), but was frustrated by the incomplete specimens. In the winter and spring of 1946 more complete specimens were collected and it was determined that the trees were not the Chinese swamp cypress.

Cheng thought the tree represented an undescribed species and a new genus and in the fall of 1946 sent herbarium material to Dr. H. H. Hu, director of the Fan Memorial Institute in Peking (Beijing). Hu was aware of Miki's article and noted the similarity of the Miki's fossils and the specimens he received. Herbarium specimens were also sent to Professor Elmer D. Merrill of Harvard's Arnold Arboretum, who immediately corresponded with Professors Cheng and Hu, requesting seed and providing funding to them for a special seed-collecting expedition. The expedition was undertaken and seed arrived at Arnold Arboretum in early January and in March 1948, and was immediately shared with institutions and individuals around the world.

In the same year Professors Hu and Cheng described the new conifer in the Bulletin of the Fan Memorial Institute of Biology. The tree was given the name Metasequoia glyptostroboides Hu & Cheng. The generic name, first used by Miki, was derived from the Greek meta, meaning alike or akin, and Sequoia, the generic name of the coast redwood, to which the tree resembles. The specific epithet, glyptostroboides, is a reference to the genus Glyptostobus, the Chinese swamp cypress with which the tree was initially confused. The popular common name of Dawn Redwood, was a suggestion of Ralph W. Chaney, a professor of paleobotany at the University of California, Berkeley. The use of "dawn" in the name was an attempt to emphasize the tree's early fossil record.
