Coreopsis auriculate

Common Name(s):
Ear-leaved tickseed, Lobed tickseed, Mouse-eared coreopsis
Herbs, Native Plants, Perennials, Wildflowers

Coreopsis auriculate, also know as mouse-eared tickseed is a native stoloniferous perennial in the Asteraceae family.  It grows easily and is low maintenance making its long blooms attractive in borders and beds and it naturalizes easily. It tolerates humidity well and some dry conditions, but it is not as drought tolerant as some other species of Coreopsis. Deadheading of spent flower stalks is tedious for a large planting, but it will encourage additional bloom. Shear plants in mid-summer to promote a fall rebloom and to tidy lanky unkempt foliage. With ideal growing conditions, it spreads over time to form an attractive mass planting.  Do not fear for the spread is easy to check if you need to keep it in line. Divide clumps in the spring to spread around your garden or share with friends.  

Nana’ is a dwarf selection that typically grows to 6-9” tall so it works well in the front of a border or along an edge. Do not plant it from seeds collected from your own plant as it will not grow true to form.  Divide or make cuttings to propagate this cultivar.

Bright flowers and long bloom provide an excellent accent in borders or meadows. Best in groups or massed. Also effective as an edger for walks/paths. Will form colonies if allowed to spread.

Regions:  Mountain, Piedmont, Coastal plains

Seasons of Interest:

     Bloom:  Spring, April-June      Nut/Fruit/Seed:  Late summer

Wildlife Value:  This plant tolerates damage by deer.  Its flowers are attractive to butterflies and other pollinators.  Songbirds eat the seed.

Insects, Diseases, and Other Plant Problems: No serious insect or disease problems but crown rot may occur if grown in moist, poorly drained soils. It will sprawl out if grown in moist and/or fertile soils and it will show foliage burn in hot summer climates if drought stressed.

Ear-leaved tickseed has basal, hairy, ovate to elliptic leaves (to 3” long) are deep green. Each leaf has a distinctive pair of small lateral lobes at the base of the blade which resembles the shape of ears, hence the common names of ear-leaved tickseed or mouse ear coreopsis.
Ear-leaved tickseed has daisy-like flowers (to 2” wide) have 8 yellow rays (each having a three-lobed apex) surrounding a yellow center disk. Flowers bloom primarily from April to June atop upright flower stalks rising 18” tall.
Ear-leaved tickseed is easily grown in medium moisture, well-drained soil in full sun. Plants tolerate humidity and some dry conditions, but are not as drought tolerant as some other species of Coreopsis. Prompt deadheading of spent flower stalks can be tedious for a large planting, but does tend to encourage additional bloom. Plants may be sheared in mid-summer to promote a fall rebloom and to remove any sprawling or unkempt foliage. In optimum growing conditions, this stoloniferous perennial will slowly spread in the garden over time to form an attractive planting, but spread is easy to check. Clumps may be divided in spring.
