So far I only have this one volunteer plant which I hope will reproduce. It has bloomed continuously from early Spring and is still going strong though we are now into September. It produces loads of flowers despite poor sandy soil, extreme heat and dry periods, and it also has survived the torrential rains of Fay. This free-flowering no-work airy plant with almost no leaves looks great in the border.

COREOPSIS Verticillata - Thread-leaved Coreopsis - Medium 24" - Plant 14" apart. Golden yellow with deep green wispy foliage.
General Information:
Especially free flowering - continuously in bloom from early summer right into fall. Makes a good cut flower with its unusual narrow tapered foliage. They spread readily and can be used in a naturalized planting, on a sunny bank, or in the traditional border. While they attract butterflies, they are deer resistant.

These are a perennial in zones 4-9. They need full sun and well drained soil that is fertile and somewhat moist. They produce yellow flowers on top of 1 1/2-2' stems. The foliage is a deep green. They bloom late spring to late summer.
These are a great addition to cut flower arrangements.
