Type 2 clematis are a little more work in that they require careful pruning in the spring and every so often need to be cut down after blooming to rejuvenate them and get rid of a lot of dead wood. I think it is worth growing some of them because of their early bloom and large flowers.
It is important to prune your roses each year, opening up the center, taking out all stems that are pencil thin and leaving some thicker and thinner canes. Don't forget to feed them and they will reward you with gorgeous blooms. I bring mine down to about twelve inches and they fill out and up beautifully!
Have a wonderful weekend!
