Rhubarb Ace Of Hearts, Rheum 'Ace of Hearts', Rheum 'Ace of Spades'


A very ornamental plant, Rheum x hybridum 'Ace Of Hearts' (Rhubarb) is a clump-forming rhizomatous perennial grown primarily for its large, heart-shaped, deep green leaves adorned with showy beet-red undersides. Blooming from late spring to early summer, feathery plumes of pale pink flowers rise on tall flower stalks above the foliage. A dramatic accent plant for borders or near streams and ponds. Ace of Hearts' is a hybrid between the giant Rheum palmatum (Chinese Rhubarb) and the smaller Rheum kialense, making it well-suited to smaller gardens.
