Selaginella stauntoniana is another Don Jacobs's introduction that thrives in southeastern gardens. Throughout the summer, this small semi-deciduous spikemoss produces 8" tall upright green fronds about every inch from a short-spreading rhizome. Since it occurs in the wild on dry rocky cliffs, we have found Selaginella stauntoniana adapts well to dry woodland gardens. Our 4-year-old patch is 1' wide. Thanks to Pam Harper for sharing this with us and to fern guru Dr. John Mickel for confirming that we have the true Selaginella stauntoniana.
