Botanical Name

COSMOS sulphureus 'Limara Lemon'

Plant Common Name

Sulphur Cosmos

General Description

This diminutive cosmos packs a punch with multitudes of brilliant yellow blooms displayed atop extremely dwarf, bushy plants. Uniquely short in stature, this cultivar is a form of golden cosmos, a tall, annual species native to fields and open areas of Mexico. ‘Limara Lemon’ is ideal for use in containers, as a bedding annual, or for edging well-drained mixed borders.

The many-branched stems of this low-growing gem are lined with ferny, deeply divided, rich green foliage, and are topped throughout summer with numerous 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.
