Coreopsis auriculata 'Zamphir'
Ear-leaved Tickseed, Mouse-ear Tickseed
Bloom Time: Mid-spring to early summer
Coreopsis auriculata 'Zamphir' is a compact selection that forms a low mound of small rounded green leaves. It typically grows up to 15 inches (37.5 cm) tall. It is distinguished from other cultivars of this species by the uniquely-fluted, orange-yellow petals on its daisy-like flowers that grow up to 2 inches (5 cm) in diameter.
USDA hardiness zone 4a to 9b: from −30 °F (−34.4 °C) to 30 °F (−1.1 °C).
How to Grow and Care
Most varieties are very easy to grow and are not particular about soil quality or soil pH. Many can be grown from seed, either started indoors, 4-6 weeks before your last expected frost, or direct-seeded outdoors. Many will seed themselves. However, the hybrid varieties do not grow true to seed.
Coreopsis will need regular water when first planted until they are established. After that, they are quite drought-tolerant.
Deadheading will keep the plants blooming throughout the summer. Some of the smaller flowered varieties are difficult to deadhead, and you may prefer to shear the plants once the first flush of flowers fades. They will fill in quickly.
Most Coreopsis plants will form tidy clumps, but some taller species may require staking to look attractive, especially if grown in partial shade.
Although they are rugged plants, they don't tend to live more than 3 to 5 years. A decrease in flowering signals it is time to divide the plants or plant some new ones from seed.
