Poppy 'Swansdown'

Papaver laciniatum
Long-necked 'Swansdown' has sturdy stems holding up huge fully double pure white blooms with cut petal tips. It's a real 'ta-dah!' moment when they burst out of the confining buds and unfurl. Lovely in the spring to the early summer garden, where their bright beacons perk up dark flowers like 'Bowles' Black' viola and 'Black Knight' snapdragon. Self-sows.

PLACEMENT & CULTIVATION
Double feathered poppies have bloomed in cottage gardens and ancient pleasure grounds since the 1600s. Their sea-green buds are crooked downward until lifting and bursting forth in a ball of finely cut petals. Cottage gardens and borders are natural homes for these antique flowers, grown with other early summer bloomers and often removed after flowering to make room for later summer flowers. Allow a few to self-sow if desired.

These plants prefer evenly moist soil, but can tolerate drought. About an inch of water per week.
