I have tons of Shastas to trade. I can send you a flat rate box if you like. Would your cannas be hardy in zone 6? I'm afraid the calla lilies wouldn't work here. I'd love the tall David phlox and some of the pink or white coneflowers if you have enough to make a box.

I agree. Daisies love sun and the more the better. In fact I just moved a bunch of "Becky" to another part of my garden over the weekend. I always move plants in the summer - if I waited until fall I'd never make room for anything else. That goes against most gardening advice, and it's a little more work, but I have pretty good success as long as it's not going to be obscenely hot or dry for a long period of time. Keep your eye on the weather forecasts and try to time it just before a rainy period. When you dig your new hole and put in the plant, fill it with water before you pile more dirt on top. That helps keep the roots moist. You have to be sure to keep them well watered (that means every day) until they start to perk up. And tie them up if they start to droop. I've got so many daisies I'm willing to take the risk. But if you're not, then wait until the weather cools a bit.

Wait until the entire flower head has dried on the plant...including the area of stem just below (should be dead looking). Then cut the head off and allow to continue to dry for a few days indoors. Then carefully remove the surface of the head...the seeds will be just below (near the core of the flower). Here is a link that might be useful: Shasta seeds

UHMMMMM.. oops. ... cut them before they fade .. sunshine fades everything... cut as they open ... ken
