Cosmos 'Xsenia'

Cosmos bipinnatus
Cosmos 'Xsenia' changes with the light! In full sun, the petals appear bright pink, and as the light fades in the evening (or on cloudy days), the orange tones wash over it like a glorious sunset. Easy to grow and undemanding, stake early in windy areas and deadhead for continued bloom.
