Features to Note:
Good for Cut Flowers, Long Blooming 4 weeks or more, Plants that attract Butterflies, Deer Resistant
Wonderful, free flowering daisies in colors from yellow through bronze and mahogany. You can have them for years, but the original plants will only last a season or two. The plants self-seed readily, and if you learn to recognize the slightly hairy seedlings and allow a few to develop where you want them, you can have as many as you want
Self sows readily. Deadhead to prevent over seeding.
