Tickseed/Lance Leaved Coreopsis ( Coreopsis lanceolata )

This Texas wildflower blooms with the rest of them from early March to early April. It is native to the US east of the Rockies.

This will grow in part shade to full sun and takes a couple of years to really settle in rarely blooming the first year. If you keep dead heading the flowers blooming time can be greatly extended.

Since the flowers tend to flop they are often grown along barbed wire fences so the flowers can rest on the wire and remain upright.

Often used to bring some seasonal color to xeriscaped gardens.
