Large-Flowered TrilliumBy May, the ephemerals are gone from all but the highest elevations, so it's time for the Trilliums to take over.
The Large-Flowered Trillium is perhaps our best-known, both for its beauty and relatively common occurrence.
They often cover entire slopes. As with all Trilliums, the plant parts come in threes - three leaves, three petals, three sepals.
The pure white flowers (often up to 4" across) stand erect on a short stalk emanating from the center of the 3-leaf whorl. Notice the lovely, delicate waves along the edges of the petals. The leaves are 8-10" long, 4-6" wide, and the plants usually grow  10-16" high.  The blooms will turn pink after fertilization, mimicking the Catesby's Trillium. Cateby's however, start out pink and its flowers are reflexed (hiding under the leaves) rather than erect. Large-Flowered Trilliums (as with most) prefer rich hardwood slopes, not too much sun, not too much shade, mostly at elevations between 3000-4000 feet.  Around Asheville, they're in full bloom all up & down the Parkway from mid-to late May.
A note on the nomenclature (naming conventions) on this site: Scientific names and classifications are constantly being argued and changed, and it drives me nuts. Although I use many different sources for knowledge, for naming consistency  I  use the  "Manual of the Vascular Flora of the Carolinas" by Radford, Ahles and Bell, 1968 edition. This book is a well-established authority for the plants of our region and I've been using it for years. If for some reason I must use a different source for a particular plant, I will make note of it within the descriptive text. Don't like it? Tough!
