Flowering this week at JLBG is the amazing Miscanthus transmorrisonensis. Many gardeners, who blindly believe everything they read/hear think the genus miscanthus is the horticultural version of the devil itself. Like everything in life, it’s all about those pesky details, which so many people simply don’t want to be bothered with.
Most miscanthus in the horticultural trade are selections of the species Miscanthus sinensis. Some selections of that species reseed badly and should be avoided in gardens. Others are sterile or nearly so, and unquestionably still deserve a place in American landscapes.
If we make good/bad evaluations at the species level, what would happen if visitors to the earth had their first encounter with a Homo sapiens that was a less than ideal representative of the species at large. They could easily assume that the entire species was a problem and should be eliminated. It’s fascinating that such species based prejudices are acceptable with ornamental plants, but not with people.
Then there are species, which have proven themselves to be complete without seed in our climate, such as Miscanthus transmorrisonensis. All plants in cultivation all appear to be derived from a 1979 Ferris Miller (Chollipo Arboretum)/ Paul Meyer (Morris Arboretum) collection at 9,500′ elevation on Taiwan’s Mt. Daxue. We have grown this for 30 years in rather good conditions, and have yet to see a single seedling. The beauty of this species is that it flowers continuously from summer into fall. I guess it’s too much to ask for environmental fundamentalists to actually pay attention to facts.
