@richrollgardener @gardening I tried growing Trillium grandiflorum from rhizomes but did not have success, with the plants surviving no more than about two or three years and flowering only in the first or second year. The plants were in shade, but perhaps they needed a little more sun, or the soil conditions were too dry. I also planted three Geranium maculatum plants in the same general location. One of the three plants survived and has thrived, which encouraged me this year to try two more rhizomes. I did thin some vegetation to let a little more sun in, so I do not know whether that helped the Geranium maculatum, but hopefully the two newly planted Geranium maculatum rhizomes will create the woodland garden I had hoped for with the Trillium.
