Gardeners' Notes:

This is my second year of having this trillium and have found it to be pretty tough. Purchased from Plant Delights, it was in pristine condition when I planted it. Buds appeared and were promptly nibbled off by either a rabbit or squirrel. Grrr! The plant disappeared entirely over the summer, and I assumed all was lost, given the drought conditions we experienced. Much to my surprise, I unearthed the trillium bulb while moving plants around last fall. So I transplanted the bulb and sure enough, it came up this spring. One bud was eaten off, but the other survived and bloomed.

Is found in Louisiana, in rich ancient woods east of the Mississippi River. It is relatively invariant in flower and leaf, although as is the case with many red-maroon flowered sessile species, pure yellow forms can very occasionally be found. Similarly, forms also can be rarely found with all-over silver leaves. With dark red-maroon flowers, it has strongly mottled leaves, in flavors of green and bronze. It is true to name, the flowers emitting a fetid odor which is especially noticeable on warm still days.
