The Zagreb coreopsis was given to my by my daughter, Laura. Very easy to grow and I love their mounding habit, also easy to divide. I have some in the garage flower bed and she just gave me some more plants and I chopped them into many pieces and planted throughout other flowerbeds. Will look forward to seeing how much they grow come next spring. Maintence free, just deadhead the blooms to insure more blooms, goes dormant in the winter.
