I personally don't know, but my impression is that daisies are fairly sturdy. Of course, plant them in a location far from heavy drafts. Ask your nursery worker what they recommend. I usually plant seedlings to save time, let them "mature" a little in my kitchen, near the window, then replant them outdoors. Have had luck with seed in yogurt cups, (a whole tray of them, whichever sprout get replanted, eventually) but as my freelancing career expands, other corners are being cut, LOL. IMHO, don't waste time, get the seedlings / ready made ones right away, and in a week or two put them outside in fair, mild weather. I visualize a combination of lavender, white, and yellow daisies, what a wonderful springtime garden!
