Gardeners' Notes:

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

T. catesbaei seems to be the first trillium to re-populate disturbed areas. It is more tolerant of clay soil that other trilliums.

It is a small dainty plant usually less than a foot tall, and one of the last trilliums to emerge in the spring. The flowers are below the leaves making it less showy than other varieties but the flowers are pretty with a flowery smell. Petals can be pink or white and usually long and curling but sometimes short and only curved.


This plant has been said to grow in the following regions:
