We’re euphoric about this Euphorbia, and that’s no euphemism. ‘Ascot Rainbow’ is a riot of ever-changing color. Blue-green leaves with creamy yellow edges are its summer wardrobe. Cool weather inspires a costume change, with intense red tones.
Like many spurges, ‘Ascot Rainbow’ performs best with well-drained soils and resents wet feet in winter. Keep it happy, and you’ll soon know why this Australian introduction earned the Royal Horticultural Society’s highest honor, the Award of Garden Merit.
Height: 20”. Hardy in Zones 6 – 9.
