This is one part in a new weekly series featuring the UC Davis Arboretum’s “40 Plants You (Probably) Have Never Heard of – But Will Love,” 40 can’t-fail, easy-care, low-water plants well adapted to our region but hard to find.

Dwarf mouse-eared tickseed

Coreopsis auriculata ‘Nana’

Size: Ground cover; under 1 foot high and wide.

Exposure: Full sun.

Bloom season: Golden flowers April to June; can rebloom in fall.

Pruning needs: Shear off spent flowers to encourage continued bloom.

Water needs: Medium to low water; once established, water once a week or as needed.

Snapshot: A low-growing perennial, this little tickseed is useful for edging and the front of the flower border. Bees love it, too. With leathery green foliage and daisylike gold flowers, this plant can be sheared in mid- to late summer to promote a fall rebloom and to remove any sprawling or unkempt leaves. Over time, this coreopsis will spread in the garden by underground stolons to form an attractive ground cover.
