I first fell in love with the charming little blooms of forked bluecurls (Trichostema dichotomum), also known as bastard pennyroyal, in a photograph. Acquiring the seeds so I could grow it was not easy, though. The only seed source I could find was from plants growing in Florida, and though they germinated well and produced healthy, bushy plants, they didn’t even start making flower buds before frost here in PA. Finally, I was able to score a few plants grown in PA, and success: flowers in September! The bushy plants, which usually reach about 2 feet tall, have lightly aromatic, green leaves that can have a grayish tinge due to a covering of fine hairs. My plants also had some red along the edges of the leaves—a pretty complement to the small but abundant, intricate, blue-and-white blooms. You sometimes see that red leaf blush in other photos, but I don’t know if it’s due to particular growing conditions or if its likely to appear in the seedlings from these seeds. Forked bluecurls is native to eastern and central North America. Full sun to light shade. Annual.
