[1] Peak flowering occurs in mid-May, slightly later than the single-flowered forms in the garden and provides a longer show because of its numerous petals.

This large-flowered trillium requires a filtered or partial shady spot with neutral and moist soil that is rich in organic matter.

[2] Foliage emerges and stays green through summer and fall, as do its seeds and fruits.

This showy beauty combines well in naturalistic gardens with other woodland favorites such as Phlox divaricata, Cypripedium parviflorum var.

[1] Mrs. Copeland had an abiding interest in trilliums and made sure her shaded garden was full of these spring beauties.
