Bloom Time: June - August

Maintenance: Low
General Culture:
Easily grown in dry to medium moisture, well-drained soils in full sun. Performs well 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. Shearing plants in mid-summer (early August) when bloom usually tapers down will remove sprawling or unkempt foliage and will encourage a fall rebloom. 慓olden Gain?can spread in the garden by rhizomes and self-seeding, particularly in moist fertile soils. Clumps may be divided in spring. Propagate from cuttings.
Noteworthy Characteristics:
慓olden Gain?is a compact form of threadleaf coreopsis. It typically grows in a dense, bushy clump to 18?tall. Bright yellow, daisy-like flowers (1-2?diameter) with untoothed rays and darker yellow center disks appear singly in loose clusters (cymes) in a lengthy late spring to late summer bloom period which sometimes extends to first frost. Palmately 3-parted leaves with thread-like segments lend a fine-textured and airy appearance to the plant. Plants in the genus Coreopsis are sometimes commonly called tickseed in reference to the resemblance of the seeds to ticks.
Problems:
No serious insect or disease problems. Slugs and snails may occur. Tends to sprawl, particularly if grown in moist and/or fertile soils. Crown rot may occur if grown in moist, poorly drained soils. Uncommon diseases include botrytis, aster yellows, powdery mildew and fungal spots. Plants will not spread invasively in the garden as species plants sometimes do.
Uses:
Borders. Also effective in naturalized areas, wild gardens or cottage gardens. Good plant for areas with poor, dry soils.
