Other than Moonbeam, this is the best selling coreopsis out there. Highly drought tolerant and easy to grow, Zagreb is a tickseed that blooms and blooms all summer. It is not an invasive spreader but will certainly fill an area with time and therefore is a perfect candidate for dividing every few year. One of my favorite coreopsis, if not my favorite.
