Types of Coreopsis

Perrennials

Coreopsis grandiflora is a perennial species also known as the butter daisy. If you start the plant early in the spring, you can expect to see blooms the first year. The grandiflora species can grow as much as three feet tall. Coreopsis lanceolata is another perennial that will bloom all season long if you frequently remove dead flowers.

Annuals

• Coreopsis tinctoria and coreopsis drummondi are the annual species. This annual type is frequently called calliopsis. This is a hardy plant that can grow to heights of three to four feet. It is a garden favorite because It grows very quickly, which makes it unfavorable for growing in pots or packs. Gardeners also use it as ground cover. Typical colors for coreopsis blooms include purple, garnet, crimson, chestnut and mahogany.

Dwarf

• Dwarf species of coreopsis only reach a maximum heitht of 12 inches. Gardeners frequently use these plants as garden borders. The flowers are yellow with red blotches in the center or as completely red blooms. The plant will naturally reseed if you leave the blooms in place. Gardeners also use dwarf coreopsis flowers as cut flowers to fill out bouquets.

Threadleaf

• Threadleaf varieties of coreopsis have leaves thinner than other types. The leaves will resemble small threads. The plant actually resembles a weed until the flowers begin to bloom. Typical types of threadleaf coreopsis include Golden Showers, Zagreb and Moonbeam. These types all have yellow flowers, though the shade of yellow varies. Over-watering will cause the threadleaf coreopsis to grow too much and not put out flowers.
