My Christmas cactus only puts out one flower at a time, but it just finished with a bloom. I was expecting that, given a few days of sunshine, my heather plants would be blooming soon. Of course, that was before 6 inches of snow got dumped on them. I'm not aware of anybody else around here that grows heathers or heaths (Royal Oak Michigan, north of Detroit), but they really do put on a great show-- especially the Springwood Pink and Springwood White, with big mounds of pink and white buds, right in February & March when you really need them.
