Buttery yellow flowers are produced in large flat umbels from mid spring through to late summer. This is a smaller achillea, perfect for gardens where space is limited, and is well behaved, growing slowly to around 0.5mH x 0.5mW. The occasional watering during the hottest parts of the year will keep this achillea looking good. Pruning off spent flowers seems to encourage some spot re-blooming for autumn. Full sun through to some afternoon shade.
