Clematis Bud

Living so close to the Lake the air tends to be cooler by my house & my plants usually bloom about 2 weeks later than those of my friends who live further inland! All the clematis plants at the Botanical Garden that we saw last Sunday (& they had about 5 or 6 different varieties) were in full bloom, while mine is just starting to bud. I'd say about another week or so & the trellis will be full of deep purple flowers!  I love these! :))
