Is Trillium a neglected California native coveted abroad and deserving more attention at home or a multifaceted research subject? The taxonomy is unsettled for sure, propagation protocols are sketchy, nursery suppliers are easier to find in Europe, the UK, Oregon, Washington, and Canada than in California, botanic garden displays are bigger and perhaps more complete in Scotland and England, gardeners in New Zealand and other parts of the world grow more trilliums than Californians, and the market economics are distorted, while native habitat is disappearing.
Trilliums, all parts in multiples of three, are much admired by wildflower enthusiasts and considered harbingers of spring in their native distributions and in gardens nearly worldwide, whether “Toadshade” (sessile types) or “Wake robins” (pedicled types). Despite significant variation in flower shape, size, leaf appearance, fragrance, and petal color, most folks know the California Trilliums as either white or maroon and may not realize there are 5 different species (with 2 or more yet to be “published”?), again depending on the key, flora, or plant list used. But, what about the pinks, reds and yellows; are they hybrids or just species variation?
