I've had this clematis for several years and after the first year it has never failed to impress me with it's beautiful blooms and vigor. I've had to move it three times over the past eight years, most recently a few weeks ago, and I have no doubt it will bloom as it always does with a big flush of blooms in mid-spring, and then (usually) a small flush of blooms in late summer. The rich purple-blue blooms are large and very full looking. As others have mentioned, after the outer large petals of the double flowers fall off the inner, finer puff of petals remains for at least another week. The blooms gradually turn a lighter shade of silvery purple that is quite pretty. The first year the blooms were mostly singles with a few doubles, but since then it has bloomed nearly all doubles in the spring and a mix of doubles and singles in the late summer flush. After the blooms fade, the shiny, fluffy seed heads if allowed to remain are ornamental as well. It is a hardy and strong grower in my zone 6b garden.

The blossoms on my MultiBlue were stunning this year. Even when the outside petals turn brown and fall off (with a little help from me) the inside puff of petals lasts several more weeks.
I found that placing rocks around the roots helps keep the roots cool while at the same time allowing the vine to have the sun it needs.
