This bulb should be planted in the Fall. Due to the seasonality of bulbs, items are not always in stock. Call for availability. Sword-like foliage on a sturdy stem supports the most recognizable flower imported from The Netherlands. Plant in well-drained soil in full sun or partial shade. Exposure to full sun will bring out the rich colors that Tulips offer. Partial shade will enable a longer blooming period and still offer a colorful addition to any garden. Viridiflora Tulips are a distant cousin of the Single Late Tulip class. These rare tulips are easily recognizable by their green stripes and bloom late in the spring, 18-20 inches.
