Coreopsis prefers full sun with moist, well-drained soil but can sprawl if grown in too fertile soil. It can be an aggressive self-seeder and will form colonies and should be planted in areas where this would not be a problem. Deadheading of spent flowers will help control self-seeding and encourage additional blooms. Growth Habit Lanceleaf Coreopsis tends to get only about 12-14" both tall and wide at maturity. This deciduous perennial blooms early in the summer and blooms through out the summer. Toxicity Coreopsis is deer resistant and non-toxic to pets.
