Leopard's Bane (Doronicum) is one of the few daisy family members to bloom in spring, and usually manages to coincide with the last of the daffodils. It has large (2-3" diameter) flowers, held high above the foliage and is an easy-going plant, useful for getting a flower border off to an early start, or for growing towards the front of a shrub border. 

Since its foliage appears early, clumps may be grown in front of large hybrid daffodils to mask the foliage while it dies down. They also look good teamed with cowslips on a grassy bank to create a natural spring display. Try contrasting it with scarlet tulips. It's happy in sun or partial shade.
