Painted Trillium (Trillidium undulatum) is a perennial native to eastern North America’s humid forests. It grows up to 45 cm in height and is characterized by its three large, oval, wavy green leaves, arranged in a whorl at the top of a slender stem. In the spring, painted trillium produces a single delicate flower with three white petals, marked with pinkish-red streaks at their base, giving it a painted appearance. This plant thrives in shaded, acidic understory environments, adding a graceful and colourful touch to woodland gardens. Painted trillium is a slow-growing species that takes several years to produce its first flower.

Sociability index: 1 → Indicates the plant’s behaviour in space and its interactions with other plants.

Ecological roles
Painted trillium plays an important ecological role in the understory. Its early blooming attracts pollinators, especially bees, which assist in understory plant pollination in the spring. The small bright red berries it produces at the end of the season provide food for small animals and birds, contributing to seed dispersal and forest floor regeneration.

 

Upon receipt, it is important to place the packet containing seeds in the refrigerator until sowing.

Painted trillium seeds require cold stratification to ensure germination. See the growing notes below for more details.

Growing Notes | Stratified Seeds - Painted Trillium

Upon receipt, it is important to place the packet containing the painted trillium seeds in the refrigerator.

Painted trillium grows in shade or part shade and prefers acidic soil rich in humus that is moist and well-drained.

Painted trillium seeds require a 90-day cold and moist stratification period, followed by a 30-day warm stratification period, then a second 90-day cold and moist stratification period to ensure germination.

The painted trillium seeds offered by Akène are sold in a sealed bag containing moistened vermiculite. The first stratification period began in mid-August. Depending on the month of receipt, they will therefore be at a different stage of the stratification process. Here is the schedule to follow to complete the dormancy cycle:

Mid-November: take the bag out of the refrigerator and leave it at room temperature, away from light and in its original packaging, for about 30 days for the warm stratification period.

Mid-December: place the same bag back in the refrigerator for a second cold stratification period of at least 90 days. The seeds are ready to start indoors around mid-March. You can also start them outdoors once the risk of frost has passed in your area, keeping the bag in the refrigerator until sowing time. Check the seeds in your refrigerator from time to time to make sure they have not begun to germinate.

Sow the seeds about 3 mm deep in a well-drained substrate. Keep the soil consistently moist but not waterlogged.
