I am plant fickle also. I'm in my second iris period, two rose periods, one with daylilies, two with hosta, one with ornamental grass etc. House plants have been the same thing...cactus, african violets, amarylis, orchids...etc. Now in the yard it is iris and hosta which I am still adding and a large rose garden which I just maintain. I'm getting to old to start over with anything again but some of those colorful new daylilies sure look good.
