Cosmos bipinnatus A sunny diversion from the standard cosmos, this new pastel lemon yellow-colored, dwarf cosmos offers the same showy flowers and ease of care as its pink-paletted brethren.  Among the first of all our cosmos to bloom, Xanthos puts on its sunny display on compact plants that reach only 10–24 inches tall. A beautiful selection for containers, beds and borders, and it requires no staking! 2016 Fleuroselect Gold Medal winner. Approximately 85–160 seeds per gram. Germination code: (1) or (4)
