I bought this plant from Wagler’s Greenhouse in 2014. It did very well and I always enjoyed working around it because of the nice fresh scent. I also like the frilly, finely cut leaves. I will have to learn more about overwintering Geraniums and Pelargoniums because sometimes they are not readily available.
