Trillium is one of many plants whose seeds are spread by ants. At maturity, the base and core of the trillium ovary turns soft and spongy. Trillium seeds have a fleshy organ that produces small fruits that attracts ants. So, area residents are encouraged to enjoy its gentle beauty as they discover Trillium in the woods, alder thickets and along secluded forest paths. Photograph them, point them out to children or co-hikers, but do not pick them.

Richly marbled leaves are often showier than the flowers. Blooms March to April. The natural range of pale yellow trillium is the upper drainage of the Savannah River. Creamy-yellow flowers can have a spicy scent like sweetshrub calycanthus. Blooms mid-April to early May. Native to eastern North America, the West Coast and Asia, there are over 40 species, divided into two groups: pedunculated with flowers on a stalk or peduncle and sessile with flowers flush against the leaves.
Trilliums take four to seven years to reach flowering age, which, with difficult propagation, has led to plants being dug from the wild, putting these wildflowers near the top of the list for conservation. With elegance and quaint charm, trilliums can be subtle standouts, particularly with their sleek lines set amid frothy spring flowers. Many trilliums have showy maroon-red, yellow or white blooms and attractive mottled foliage. Trilliums are native to zones as high as 9 and as low as 3.
They can often be grown out of their natural ranges between north and south, but the translation between East and West coasts is less successful. West Coast species prefer a mild maritime climate. As woodland wildflowers, trilliums prefer high shade, though some species can take a little sun. Protect from bright noonday sun, and avoid western exposures.
Deeper shade is fine in summer, though the extreme darkness of evergreens can keep trilliums from thriving. These lovely plants have three petals that can be narrow or wide, usually ending in a point. These blossoms do have sepals, which look like pointy, narrow leaves, just under the petals in an alternating pattern the petals and sepals together look like a six-petaled blossom.
Both types of trillium flowers sit at the end of a stalk that leads down to three large, green bracts that look like giant leaves; the actual leaves are tiny and have been described as scale-like. Most of the plant is underground, and it spreads via rhizomes. Seeds are often spread by ants and mice, who eat a protein-based covering on the seed and then dump the seed, which germinates in that spot. Some trilliums are endangered or illegal to pick in the wild, so purchase yours from a reputable nursery or garden center.
These are long-lived perennials, with some plants lasting as long as a quarter of a century. They prefer shady or partially shady conditions and moist, neutral to acidic soil. They tend to flower in early spring and are dormant much of the year. RHS Christmas gifts. Help us achieve our goals Make a donation.

Division Established clumps can be lifted and divided as the foliage dies back.
Seed Sow seed as soon as it is ripe in pots of John Innes seed compost and place in a cold frame in shade.
