I like to plant Trilliums under Rhododendrons and other evergreens to enjoy the distinctive white or red blooms.
Since this native plant likes rich acid soil, it is very happy being situated with these other acid-loving plants.
It is a little particular about being disturbed after it has been planted so try to plant it in its forever home right from the beginning.
If the foliage or blossom is broken the plant will not bloom for two years and may even die.
Although it spreads by rhizomes (and will naturalize), it is not at all invasive and co-exists easily with other spring plants.
Once the weather starts to get warmer, Trilliums go completely dormant. You might want to mark their location so that you don’t accidentally dig them up.
Trillium is the official flower of the Canadian province of Ontario and the State of Ohio.
