Phormium ‘Yellow Wave’ provides a vibrant pop of color in the landscape with lemon-yellow leaves striped with bright-green margins. Growing 3-4’ tall and wide, this cultivar is a smaller, more graceful form of Phormium, with softly arching leaves. For best results, plant in full sun to part shade and provide light to regular water. Should any leaves revert to green, cut back to the base. Cold hardy to 15° F. ‘Yellow Wave’ is a recipient of the Royal Horticultural Society’s Award of Garden Merit, and is a popular choice among landscape contractors, designers and architects in mass or as accents in naturalistic, modern, geometric and Mediterranean landscapes. Leaves are valuable additions to cut floral arrangements.
