Double Late Tulips are Late Spring Tulips. Because of their shape, Double Late Tulips are also known as Peony Flowering Tulips. They are also referred to as Double Bloom Tulips. Double Late Tulips perform best in full sun in rich, fertile, medium moisture, well-drained soils. They prefer areas with cool winters and warm dry summers.
For some people who want Late Spring Tulips, I sometimes plant Angelique Tulips. Angelique Tulips have delicate blush pink flowers trimmed in white. http://www.pinterest.com/pin/73183562678881586
