Gardeners' Notes:


On Aug 13, 2010, 45eriepa from Lexington, MA wrote:

Coreopsis pubescens is a spreading, somewhat sprawling plant to 2' (60cm) high that provides non-stop yellow from July to frost. It has not self-sown for me but collected seeds germinate readily; mine came from Prairie Moon Nursery seed. It can be readily divided when growth begins in spring. It is useful, dependable, and trouble free; I find it quite tolerant of drought, such as the one we're now enduring.

Short in stature but generous with blooms. Starts the display in mid April here in Oklahoma and doesn't stop until frost with the added bonus of not needing to be deadheaded. Looks great when paired with its larger cousins like Coreopsis x 'Rising Sun' or Coreopsis x 'Jethro Tull' or with small statured fountain grasses

Does not appear to be affected by powedery mildew.
