Coreopsis Lanceolata

What is the plant

Lance-leaf tickseed grows in small clumps but forms extensive colonies. It is 1-2 1/2 feet tall and has leaves 3-4 inches long, opposite, sometimes alternate near the top where the leaves are fewer. Some of the leaves are deeply cut, almost forming 3 leaflets. Flower heads are yellow, 1-1 1/2 inches across. The yellow center or disk flowers stand out distinctly from the ray flowers, which appear to be attached just below them. Ray flowers are 4-lobed. The yellow, daisy-like flowers occur singly atop long, naked peduncles.

How to Care for the Plant

Water
New coreopsis plants need regular water to keep the soil evenly moist (but not soggy) until they are established. After their first year, these plants have good drought tolerance, but they'll bloom most prolifically with regular watering. Water deeply whenever the soil is dry about an inch down.
Pruning
Cut a third of the plant's stems back by several inches before flowers even appear. Make cuts just above a node with a leaf and bud, if possible, and space your cuts evenly around the plant. This cutting back is not necessary but will help to stagger and extend the period of blooming.
Fertilizer
Apply a light application of granular 10-10-10 fertilizer or side-dress with compost and organic amendments when new growth appears.
