Trilliums

Years ago, when we first moved into our house and I started gardening, I envied my neighbor’s clump of Trillium grandiflorum which she’d brought back from The Lake. Since I shared the shade and leaves of her oaks, I figured I could grow them too.

I bought one plant, chose what I thought was a good spot and waited. The plant did not thrive. I added two more plants in different spots the following year. They did not thrive.

Some years later I noticed a small clump of healthy trilliums growing out of the bottom of my stone wall. I knew I hadn’t planted them or even thought of cramming a plant into what looked to be an inhospitable site. Squirrels! They’d planted the fruit/seed pods in exactly the right place; I was suitably humbled. (I’ve since learned that the seeds of trilliums are attractive to ants, who help disperse them by leaving seeds in their tunnels, where the seeds germinate, so ants might deserve the credit.)

Now I have many clumps of T. grandiflorum around the garden, and my habit is to plant them amongst good sized rocks, where they seem to thrive.

T. erectum’s flower is not as large as T. grandiflorum but it is striking, usually dark red, and the plant makes large clumps. It is propagated easily by division and will also seed (although mine hasn’t).

T. luteum has an unusual yellow flower and handsome mottled leaves.

All these trilliums grow in deciduous woods in neutral to somewhat acid soil. Dig in leaf mold when planting. I top dress with compost in the spring and add a light mulch of shredded leaves. Some growers use a liquid 10-30-20 fertilizer to get bigger blooms. This can be done twice a year, as the shoots appear and then as the flowers fade.

These trilliums are available at this year’s Friends School Plant Sale (T. grandiflorum in Native Wild Flowers, T. erectum and T. erectum luteum in Perennials).

Try some, and bring home a bit of The Lake.
