What plant to use for topiary?
I recently purchased 2 topiary forms for use in my garden. Both are animal shapes, approximately 15" tall. I've never planted a topiary before, and need advice on what plant to use. I live in zone 5, and I don't want to have to bring the forms inside in the winter. What plant would be appropriate for a beginner? (I'm open to using a tender annual also, and replanting each year.) Thanks!
