I planted this caerulea last spring, and although it put forth a lot of vegetative growth, in only produced three flowers. Almost exactly one year later, it's covered with more than a hundred buds, and the first one just opened yesterday:

My caerulea "Constance Elliott" out front has close to a dozen flower buds on it as well, which is great, since that one didn't flower at all last year. The downside is that I've already found three caterpillars on them, and my normally bushy Incense isn't available to serve as an alternate host yet. :-(
