COSMOS sulphureus 'Cosmic Yellow'( COSMIC SERIES)
Cosmic Yellow Cosmos, Sulphur Cosmos
This vigorous, compact, free-flowering cosmos lights up the summer garden with multitudes of brilliant, sunny yellow flowers. It is a member of the popular Cosmic Series, which was developed from a tall annual species native to fields and open areas of Mexico. ‘Cosmic Yellow’ is ideal for use as a bedding annual, in wildflower gardens, or for filling gaps in well-drained mixed borders.
The upright, branching stems of these dwarf, bushy plants are lined with ferny, deeply divided, rich green foliage, and are topped throughout summer with numerous double and semi-double, clear golden-yellow daisies. The flowers are composed of broad yet delicate, somewhat pleated ray petals surrounding bright yellow centers, and are followed by sharp, star-like clusters of brown seeds. Butterflies will visit and flutter among the bright blooms.
After danger of frost has passed, sow the seeds of this heat-loving, drought-tolerant annual in full sun and moderately moist to somewhat dry, well-drained soil of low to modest fertility. Avoid excessive water and fertilizer, as these can result in leggy growth and fewer flowers. Plants may begin declining by midsummer, but prolonged bloom display can be achieved by sowing seeds in succession. Alternatively, the seeds of existing plants may be gathered and scattered on the ground. They should germinate quickly, resulting in fresh blooms by late summer to fall.
