|I look forward to seeing the forest understudy covered with the patches of white created by the Trillium grandiflorum.
|Although this plant seems to be fairly adaptable, the growing site still must be similar to its needs. Also yearly addition of organic mulch and allowing the plants to mature and die without removing the foliage. This allows for production by seed. Be very careful not to pull up the seedlings when weeding in the spring. In one garden I planted a patch of Trillium over 25 years ago. I found some plants growing in a thick patch of Pachysandra.
