27" tall by 12-24" wide. Siberian Iris ‘Sugar Rush’ blooms in early summer with cheerful flowers in pastel shades of silvery ivory, soft pink and butter yellow. Standing tall on sturdy stems, this stately, elegant flower flutters in the slightest breeze. Plant them in sun to part shade, they prefer moist conditions but are not suitable for ponds. They are quite drought tolerant once established. Hardy, easy-care plants, the bright green grass-like foliage adds a season long vertical element in the garden. They will grow to create large clumps and may be divided in early autumn. Great cut flowers, cut them just before they open.
