Syns Trillium sessile var luteum, Trillium viride
Wood Trillium
From Appalachian woodlands of eastern USA, this species is distinguished by its rather pointed leaves that are spotted and splashed with paler green, and small stalkless yellow-green flowers that do not open very widely.
Zones 6-9

Love the yellow variety and have it planted in front of the porch where I can see it when it blooms and enjoy the leaves too.

This trillium was one of the few thriving populations that I have. Sadly I had to put it under neutral as all of one population which was my only population was wiped out along with several nearby native plants one winter. I have planted some new ones a short location away two years ago and is nonblooming. I don't know what happened even though there was a firepit nearby but leaves don't show sighs of scorching or stresses.

I am told that if Trillium luteum does not get good morning sun the blooms will be green and not yellow. My plants have been holding yellow blooms for 2 1/2 weeks now in SE Ohio.

Positive Tiarella On Mar 18, 2004, Tiarella from Tunnel Hill, GA (Zone 7a) wrote:

This is probably the easiest trillium to grow and will naturalize through much of the country. Here in zone 7a (the southernmost area of it's natural population), it appears in mid-March and is usually gone by July 1 with a short bloom season in April.

The yellow flowers add a bright note to the garden and have a lemon smell. I like to plant trilliums with ferns to fill the bed before the ferns emerge.

Trilliums like moist soil but sharp drainage and are found on shaded hillsides in nature.

Seeds must be planted fresh to produce a seedling the following spring. Allowing the seed to dry out will delay germination by a year and germination rates will decline. First year seedlings resemble blades of grass, second year seedlings have a broader almost heart-shaped leaf, and the third year seedling will be a small, three-leaved plant. It may take 7 or more years to have a flowering plant.

One of the last trilliums to bloom in this part of the country. The yellow sepals and petals remain for weeks, giving the impression that it is in bloom for a very long period.

As soon as the seed is ripe, the plant goes dormant.

Foliage is mottled with silver and white.
