Trillium are hardy perennials. They reach from 15 to 45 cm (6 to 18 inches) in height.
They have large flat leaves, and bloom from early spring to early summer.
When in bloom, Trillium plants carry flowers of white, red, or pink. These may be single and large, or in whorls depending upon species.
A commonly grown member of Trillium in the garden is the Wake-Robin.

It is probably easiest to grow Trillium from plants bought at a garden centre, or from carefully divided plants. Plant these roots at about 12 to 15 cm deep (5 to 6 inches).
Be aware that the seeds may take up to three years to germinate. If growing species from seed it is perhaps easiest to start off indoors.
Sow the seeds into a flat on the surface. Thos flat should contain a rich, slightly acidic soil (pH 5 to 6.5). Once sown, cover the flat in a plastic bag. then place in the refrigerator for three months.
The flat should then be removed from the bag, and kept indoors at a temperature of 15 to 22 degrees celsius (59 to 72°F).
After three months, the flat should again be put in a plastic bag, and refrigerated for a further three months. After this period place at 15 to 21 degrees (59 to 70°F). Hopefully the Trillium seeds will germinate.
Once you have Trillium seedlings, they can be transplanted outdoors in either autumn or spring.
They should be grown in a shady or mainly shady part of the garden. Use a spacing of 12 cm / 5 inches (small) to 30 cm / 1 foot (larger Trillium species) apart.
It should take about five years until the plant will bear any flowers.
Trillium are not the easiest plants to grow, but are more than nice enough to make the effort.
They prefer a cool and moist soil, so supply a deep permanent leaf mold mulch for them and keep well watered.If you require more plants they can be propagated by division in the spring; however do this very carefully as it is very easy to destroy your plants!
The Trillium genus is comprised of around 40-50 species known for their distinctive three-petal flowers.
Yes, Trillium are excellent woodland garden plants, appreciated for their early spring flowers and low maintenance needs.
Species like Trillium grandiflorum (White Trillium) and Trillium erectum (Red Trillium) are commonly cultivated.
Some Trillium species have fragrant flowers, such as Trillium grandiflorum.
Trillium prefers shady to part-shade locations with well-draining, humus-rich soil.
Presently, Trillium is not considered invasive in the USA. In fact, several species are protected due to declining populations.
Trillium can be removed by careful digging, ensuring to extract the entire rhizome to prevent regrowth.
The Trillium genus includes perennial plants native to temperate regions of North America and Asia. They are valued for their unique, three-petaled flowers and whorls of three leaves, and some species are protected due to over-collection in the wild.
Grow Trillium from seeds or rhizomes, preferably in autumn. They thrive in shaded to partially shaded locations and prefer well-drained, humus-rich soil. Regular watering is necessary, particularly during dry periods, but overwatering should be avoided to prevent root rot.
