Plant Study Calliandra emarginata ‘Dwarf Pink Fairy Duster’

Family: Mimosaceae (from mimos, a mimic, referring to the sensitive leaves) Subfamily of Leguminosae characterized by flowers with small petals and numerous prominent stamens.

Genus: Calliandra (from kallos, beautiful, and andros, stamen)

Species: emarginata

Dwarf Pink Fairy Duster is a small evergreen shrub featuring pink to red powderpuff blooms from spring to frost. It grows to 2-4 feet tall and tends to be round in form. The blooms are deep pink and are actually the stamens of the flower. It re-blooms in cycles from spring to killing frost.

Recommended for zones 10 and 11, it proved to be root hardy here in 8b with no protection below 20 degrees. It requires sun to partial shade and standard to poor garden soil with good drainage. It does not respond well to fertilizer use. Drought tolerant after established, it does best with regular watering.

It can be propagated from green cuttings taken in spring or by seed. This plant attracts hummingbirds, butterflies and possibly deer. It is a popular plant for bonsai use.

Plant Study Scrophulariaceae angelonia angustifolia ‘Serena’

Webmaster post on March 13th, 2013

Family: Scrophulariaceae Figwort family annual or perennial herbs with flowers with bilateral or rarely radial symmetry

Genus: Angelonia

Species: Angelonia angustifolia x Serena

Angelonia, occasionally called Summer Snapdragon, is a tough, low maintenance plant that blooms profusely in sunny gardens. Native to Mexico and the West Indies, angelonia (sometimes also called summer snapdragon) is an upright, glabrous (hairless), somewhat bushy, tropical perennial that is noted for its long summer bloom of small snapdragon-like flowers. Plants typically grow 12-18” tall. Stems are clad with narrow, oblong to lanceolate, green leaves (to 3” long) with toothed margins. Foliage is slightly aromatic. Flowers (each to 3/4” across) bloom from late spring to early fall in salvia-like narrow terminal spikes (to 8” long). The two-lipped flowers are somewhat reminiscent of snapdragon.

‘Serena’ is the first Angelonia available from seed and so is now widely available commercially. ‘Serena’ blooms with spikes of white, pink, lavender, or purple blooms beginning in late summer and continuing until frost. A compact plant 12” to 18” tall with a 12” to 14” spread, ‘Serena’ is good for hot, dry, humid and even wet garden areas. The flowers are particularly attractive to bees, butterflies and birds. It is considered an herbaceous perennial in zones 9 – 11 and an annual elsewhere, so it will survive a mild winter here. This plant does best in full sun but will tolerate some shade. Drought tolerant after established, it does best in well drained garden soil with regular watering and nutrients. ‘Serena’ Angelonia is available as seed from Parkseed, and 4” plants are widely available in April or May in most garden centers. May be propagated from stem cuttings.

Texas Sage

Family: Scrophalariaceae Figwort family annual or perennial herbs with flowers with bilateral or rarely radial symmetry

Genus: leucophyllum (from Greek leukos (white) and phyllon (leaf))

Species: frutescens ‘Compactum’

Texas sage is a shrub native to the desert of Northern Mexico, Arizona, and South Texas. With silvery green leaves and pink, white or purple flowers Texas sage is one tough plant! It can face droughts, freezes, high winds, salt spray, hungry deer, and blazing heat and keep right on performing beautifully. This shrub, however, is not good for areas with high rainfall. You can compensate with perfect drainage and avoiding the use of sprinklers. No supplemental water is needed after the plant is established.

Five-lobed tubular 0.5-1 in flowers are borne singly in the leaf axils. They have spotted throats and a typical foxglove family character. Texas sage bloom best in hot, humid weather. The flowers appear after summer rains, sometimes covering the plants with blossoms for a spectacular week long display.
This shrub requires full sun, 4 to 6 hours minimum, and it prefers shale, gravel or concrete to compost or fertilizers. Amend soil with crushed granite when planting.

Appropriate for Zones 7 – 10. This species is hardy to 10ºF.
‘Compactum’ is slow growing with a dense growth habit, only reaching 3-5’ tall with a 3-5’ spread. The flowers are pink and bell-shaped and contrast nicely with the silvery-gray foliage. The shrubs shear well and can be used as hedges or containers, as long as the site has good drainage.

Genus: Artemisia (after the Greek goddess Artemis. Perennial herbs, shrubs, and sub-shrubs)
Species: Powis Castle (introduced 1972 by Mr. J Hancock of Powis Castle, Wales)

Artemisia “Powis Castle” is an easy to grow herbaceous evergreen perennial grown for its feathery silver foliage. It grows to 2-4 feet tall, 4-6 feet wide.

The flowers are inconspicuous and should be removed when possible to improve foliage growth. This plant does well in full sun to partial shade. Drought tolerant after established, it is suitable for xeriscaping. Suitable for dry spots but tolerant of rain and humidity if well drained. Best in neutral to alkaline soils.

In early spring, trim leggy branches to 8”-12” leaving some budding leaf nodes to fill in. Powis Castle can be propagated from green cuttings taken in spring or by layering. It can be an attractive cover for bulbs or an underplanting for leggy shrubs if height is managed properly.

It is not attractive to deer or rabbits.

Coral Honeysuckle ( Image credit

Family: Caprifoliaceae Honeysuckle family, mostly shrubs and vines
Genus: Lonicera (after Adam Lonitzer 1528-86, German naturalist)
Species: sempervirens ( from Latin semper, always, and virens, green)

Coral Honeysuckle is a native, twining, evergreen vine. The vine may climb to 30’. It is nearly ever blooming, sporting flowers well into December and resuming in spring. Blooms are clusters of drooping tubular flowers in shades of coral, with cultivars available in pink or yellow tones. The fragrant flowers are particularly attractive to hummingbirds as well as bees, butterflies, and birds which will consume the red berries that follow the flowers. The vine is semi-evergreen and appropriate for zones 5 -10.

This plant does well in full sun to partial shade. Drought tolerant after established, it does best in well drained garden soil with regular watering. May grow from seed and can be propagated from cuttings.

“This is my favorite vine, so polite with gentle twisting tendrils becoming woody over time. Add to the fence or side of the garage on a string or wire lattice. Blooms in even part shade but sun is best. Hummingbirds adore this.”

Plant Study Malphigia punicifolia ‘Dwarf Barbados Cherry’

Barbados cherry

Barbados cherry Photo source

Family: Malpighiaceae
Genus: Malpighia (Of, relating to, or described by the Italian anatomist Marcello Malpighi)
Species: punicifolia, also glabra (punicia – semi-hardy evergreen shrub or tree)

Dwarf Barbados Cherry is a small Semi-Evergreen perennial shrub native to the Caribbean and parts of Texas. In sun it becomes a dense mound with glossy, dark-green foliage with a looser habit in shade. The small pink and white flowers similar to crepe myrtle bloom spring through fall, attracting butterflies.

Red, cherry-like fruit ripen Nov-Feb and attract birds. The fruit may be sour or sweet and one cherry has more vitamin C than 12 oranges.

Various sources are confusing regarding the cultural requirements; it requires acid or alkaline soil, grows in limestone, clay or marl ,and is said to be either drought tolerant or shallow rooted requiring regular water and good drainage.

Good garden soil and regular water and good drainage are sufficient. Sun is required for fruit production though it does well in shade and semi-shade or indoors, producing less flowers and no fruit.

Protect at temperatures below 20 degrees, root hardy into the low 20’s, semi-evergreen in the 30’s.

This plant is easily propagated from cuttings or air-layering, also by seed but variable quality of fruit from seed.

Dwarf Barbados Cherry may be sheared for hedges or ground cover and is well suited for bonsai. Non-dwarf varieties may grow to 20’ tall.
