Clarkia is quick growing, an excellent annual for bedding or mass planting in an informal scatter garden. Can be sown in the fall in mild winter areas. When seedlings are 2 to 3 inches tall thin to 8 to 10 inches apart. Clarkia does not transplant well. This annual grows and flowers best when planted in a mostly sunny spot in cool climates.
Plants thrive in well drained soil and require limited care.
Water when dry until flowering commences. Shear back plants halfway when flowering has ceased for possible later blooming.
