NOS HELWINGIA PAGE |
Helwingia chinensis is super rare woody plant which we figure will become more popular in coming years. Heronswood Nursery has offered three clones of it and is responsable for much of the material around the US. It is generally an evergreen shrub of 8 feet tall and 4-6 ft. wide. Leaves are glossy green with nice purplish to red new growth and showy pigmented petioles in winter. It comes in a variety of leaf widths and sizes and is dioecious (one gender per plants) like hollies. Because they are not self-fertile, one needs at least one male and one female plant for fruitset. Heronswood conveniently offers one male, one female, and unsexed seedlings too. Leaves are said to be edible but we have no trusty data to prove this is a good thing or not. It's real claim to fame, a truly fun curiousity is the fused peduncle (flower stem) and petiole. It makes the smallish ivory flower appear to be coming out of the leaf or leaf base quite directly. The look is pleasant and interesting with some abundance of flowers. I'm also inclined to admire the fine texture of the narrow-leaved clones for their dagger-like look and long acuminate tips. The fruit is red to purple and usually near black by ripeness. There may be some clonal differences in early fruit color that someone could study. The smallish berry adds some interest and like the flower appears fused to the leaf blade. The species is cold hardy in USDA zones 7-8. The following variations are reported:
Helwingia chinensis
[broadleaf form]
Helwingia chinensis
var. crenata
Helwingia chinensis
[DJHC 695]
Helwingia chinensis var.
chinenis f. oblanceolata S.S. Chien
Helwingia chinensis f.
megaphylla Fang
Helwingia chinensis
[narrowleaf form] --------------------------------------------------------------------------------------------------------------------------- Helwingia japonica is another species, not yet seen much in the US, of some beauty. It is more deciduous (semi-evergreen) than H. chinensis with leaves wider, more ovate to ovate-orbicular. They are also glossy green with black fruit at maturity. Plants tend to be a tad shorter to 5 feet. The leaves are thinner, more papery and not so thick and leathery as the Chinese species. Yokoi and Hirose in the their 1978 Variegated Plants book show a nice cream-sectored clone of this species. LCH |
