Don't worry ~ They'll be fine. They'll get stronger and form a small clump over the summer. You may get some flowers this year but next year they'll be taller and put out more blooms. I've found them to be tough plants and can handle quite a bit of abuse. The hummingbirds and butterflies love them!
I've just joined the garden and noticed a thread on Maltese Cross. What do these look like and what is a good source for them? My husband is the chief at our volunteer fire dept. A maltese cross is used in the firefighter emblem and I'd love to surprise him by adding a flower of this name to my garden.
