2007 Promising Plants List

 

Acmella oleracea syn. Spilanthes acmella
Toothache plant

Asteraceae
The plant has been sold as Spilanthes acmella ‘Brede McFane’. It has no particular odor but is memorable in terms of flavor. First impression is slightly salty and not unpleasant, but this rapidly develops into a tingling, burning sensation that leaves the mouth numb – hence the name toothache plant Brède mafane is the key ingredient in le romazava, the Madagascan national dish.

Armoracia rusticana ‘Variegata’
Variegated horseradish

Brassicaceae
Horseradish is invasiveness and the dock-like leaves and insignificant flowers could never be described as ornamental. What a difference the variegation makes! The drab green, dock-like foliage is transformed by ivory marbling into something almost exotic. Variegation is often virus-induced and therefore weakens a plant, which can be an advantage in invasive species.

Conradina verticillata
Cumberland rosemary

Lamiaceae
Cumberland rosemary is an endangered native American species from the SE United States. The common name arose because there are colonies along the Cumberland River and because the plant has narrow leaves, about one inch long, that at first glance resemble those of rosemary. The foliage is also aromatic like rosemary, although to my nose it smells more minty than rosemary-like. This attractive plant has huge potential as an ornamental. It is an evergreen shrub, hardy in zones 5-7. This is one of the most exciting “new” herbs I have come across for many years. Given that this is a native American species and is endangered – and, as far as I can tell, is almost entirely unknown as a culinary herb – it is a MUST for both the Promising Plants program and for the up-coming conservation program.

Sideritis syriaca
Greek mountain tea

Greek mountain tea has aromatic, densely woolly, silvery-grey leaves and equally woolly stems. Whorls of 6-10 primrose-yellow, tubular flowers are produced in woolly spikes from summer to autumn. Greek mountain tea reaches 12-20”. Hardiness is generally given as Z8 or Z8-10 but in my experience plants can survive lower winter temperatures if kept on the dry side at the roots and protected from excessive rain and/or snow lying on the foliage. Like cats, they hate having wet fur!

Actaea racemosa syn.Cimicifuga racemosa
Black cohosh
Black bugbane
Black snakeroot
Squawroot

Ranunculaceae
Besides being valued as a lovely woodland plant for shade gardens black cohosh has a long medicinal history beginning with this country's earlier inhabitants. In the past few years black cohosh has become increasingly popular as the most widely-used natural alternative to hormone replacement therapy (HRT). The herb's popularity with middle-aged women and gynecologists grew significantly after the summer of 2002 when a large-scale government-sponsored clinical trial on HRT was halted. A 2006 clinical trial testing the popular herb black cohosh is inconsistent with the positive outcomes for treating menopause symptoms seen in the majority of published clinical trials, says the American Botanical Council, the leading herbal nonproft research and education organization.

Poliomintha incana syn.Hedeoma incana
Rosemary bushmint
Rosemary mint
Frosted mint

Lamiaceae
This is a very aromatic medium-sized shrub (3'); perennial in Zones 8-9 from Arizona (Apache, Navajo and Coconino counties) west to California, south to Mexico where it thrives in dry, sunny, sandy locations with low humidity at elevations of 4,000-6,000 feet. The entire plant has a white coating of minute felt-like hairs. The gray-green mint-scented flat leaves of Poliomintha incana are similar to those of rosemary.

Staphylea trifolia
American bladdernut

Staphyleaceae
American bladdernut is a small native tree ranging from Quebec to Ontario and Minnesota, south to Georgia & Missouri (cultivated since 1640), hardy in Zones 4-8. It produces abundant 1/3" white bell flowers on nodding 1 1/2 to 2" long panicles during April & May followed by inflated balloon-like fruit containing 3-5 hard seeds. The Iroquois used infusions of the bark as a wash for sore faces and as a (body) wash to keep children from crying. Seeds are considered to be sacred by the Meskwaki tribe and used in gourd rattles for dream & medicine dances.

Aloysia virgata
Almond verbena

Verbenaceae
Almond verbena is a woody perennial. Small white flowers are borne in 4” to 8” axillary racemes. The ethereal sweet almond or vanilla-like fragrance can stop you in your tracks! Butterflies, bees, and many other insects enjoy it. This plant is virtually pest-free and prefers full sun to partial shade and is hardy into USDA zone 8 and possibly root hardy into zone 7. It has low water requirements and is tolerant of high temperatures.

Boehmeria nipononivea ‘Kogane Mushi’
Golden ramie

Uticaceae
Japanese ramie (Boehmeria nipononivea) is very similar in appearance to its Chinese cousin, but is of smaller stature and more ornamental use in the garden. It is also reported to be more cold-hardy. A new selection of Japanese ramie called `Kogane Mushi', or simply golden ramie, has marbled leaves of green and gold variegation and makes a beautiful color contrast in the summer and fall garden. Japanese ramie is hardy into USDA zone 6.

Camptotheca acuminata
Chinese tree of joy
Chinese tree of love
Happy tree of China

Nyssaceae
The Chinese tree of joy is a fast growing deciduous tree that was first introduced into the United States by the USDA in 1911. In its native lands it is valued as an ornamental tree and for its medicinal qualities, which the Chinese have employed for many centuries. In addition to its wonderful ornamental qualities, the tree of joy has proven itself useful in modern medicine. Its bark, roots, seeds, and leaves yield a potent alkaloid known as camptothecin. This promising drug has been used to treat various types of cancer. Camptotheca acuminatas is hardy in USDA zone 8 and south.

Oenanthe javanica ‘Flamingo’
Variegated water dropwort
Variegated water parsley
Variegated water celery

Apiaceae
Water parsley is a low, spreading herbaceous perennial with pinnate leaves, much like its cousins parsley and celery. It has tiny white flowers that are borne in umbels. It can grow in very boggy or average soils, can be eaten, and has medicinal qualities. Keeping it in an area of average moisture will help to keep it in bounds. The variety 'Flamingo' has beautiful variegation. The small serrated leaflets are colored in cream, green, and pink. This variety is purported to be tamer than the green form, but I can attest to the fact that it is still very vigorous.

Salvia coccinea ‘Brenthurst’
Brenthurst Texas sage

Lamiaceae
The species Salvia coccinea is well known for its brilliant red flowers. Salvia coccinea ‘Brenthurst.’ S. ‘Brenthurst’ displays most unique and very attractive deep coral or salmon-colored flowers on foot long racemes well above the dark green, slightly hairy foliage. The flowers themselves have a subtle two-tone effect as the upper lip of the corolla is slightly lighter—almost whitish— in color than the broader and darker colored lower lip beneath. Like the species, this plant should be considered a tender perennial for all but the more mild climates.

Rosmarinus officinalis ‘Capercaillie’

Lamiaceae
This is a rosemary from Downderry Nursery in England. I am impressed by this creeping or prostrate rosemary. It was first introduced about 2-3 years ago from Scotland but I haven’t as yet ascertained where it originally came from. The Scottish name ‘Capercaillie’ actually refers to an endangered wood grouse (Tetrao urogallus). Characteristics of this Scottish grouse are mimicked in this rosemary’s habit of growth, as 2-3-foot long, evergreen branches seem to emanate from the plant’s crown in a roughly fan-like manner.

Amaranthus cruenthus xpowelli
Hopi red dye amaranth

Amaranthaceae
This plant is native to Mexico and Central America. It is a naturally occurring hybrid. Native people use the flower heads to make a red dye to color “piki” bread (a ceremonial cornbread), wool, cotton and baskets. The black seeds are edible; they can be sprouted, popped, cooked whole or ground into a high protein gluten-free flour. Young leaves are cooked as a potherb. It is a tall, bushy annual which grows to 6 feet tall with oblong to lanceolate purple-green leaves. Tiny flowers with crimson bracts are in upright, many-branched terminal panicles up to 18 inches tall.

Coreopsis tinctoria
Dyer’s tickseed

Asteraceae
Coreopsis tinctoria is an annual dye plant native to the western two thirds of North America. The pigments produce yellows, oranges and reds depending on many variables. Disk flowers are maroon, and ray flowers are all maroon to all yellow through varying amounts of maroon at the base and yellow at the tip. I grow the maroon form of this dye plant simply because it is more unusual than the many yellow and yellow with maroon forms. The dye pigments are not appreciably different among the various forms.

Cotinus coggygria
Smoketree
Smokebush

Anacardiaceae
Smoke tree is a source of the classic dye pigment young fustic, which gives a clear yellow with tin and alum mordants. This dye has been used since the Middle Ages as an over-dye on fabric dyed with indigo or woad to obtain Saxon Green. Other colors produced with different mordants include pink, orange-tan and gingery-tan. Twigs, wood chips, bark chips or sawdust are used as the pigment source. Cotinus coggygria is a large shrub to small tree, to 15 feet x 15 feet when mature. Flowers are small but are borne on 6- to 8-inch showy, terminal panicles adorned with long hairs that give the visual effect of smoke.
