Threadleaf Coreopsis: each 1/2 gallon
 
Threadleaf Coreopsis - - (Coreopsis verticillata)
Easily grown in dry to medium moisture, well-drained soil in full sun. Thrives in poor, sandy or rocky soils with good drainage. Tolerant of heat, humidity and drought. Prompt deadheading of spent flower stalks can be tedious for a large planting, but does tend to encourage additional bloom and prevent any unwanted self-seeding. Plants may be sheared in mid to late summer to promote a fall rebloom and to remove any sprawling or unkempt foliage. Species plants can spread somewhat aggressively in the garden by both rhizomes and self-seeding.
