Zagreb is considered a dwarf coreopsis - a perennial reaching a height of 12-18 inches. Needing dry to medium watering and full sun you will be pleased to learn it thrives in poor, sandy or rocky areas as long as there is good drainage. You can trim it back late in the summer and find it blooming again in the fall. The trimming also helps to contain the plant in its area.
