This year we are highlighting the diversity of tulips by including the division of each on the label. Tulips are placed into divisions based on shape, origin, and bloom time.
- Division 1: Single Early Tulips – Early to mid-spring flowering tulips with a wide range of colors and cup-shaped single flowers.
- Division 2: Double Early Tulips – Fully double or semi-double peony-like flowers. There are fewer colors in Div 2 than Div 1. Mid-spring flowering.
- Division 3: Triumph Tulips – Single, cup-shaped blooms that appear in mid to late spring. A hybrid division, with the widest range of colors. Tend to be short lived.
- Division 4: Darwin Hybrid Tulips – Single, large, ovoid flowers that bloom in the mid to late season. Usually in warm shades, with a contrasting eye. Reliably perennial.
- Division 5: Single Late Tulips – Cup-shaped blooms, sometimes multi-flowering and sometimes single-flowering. Available in a wide range of colors.
- Division 6: Lily-flowering Tulips – Single, lily-like flowers bloom in mid to late spring. Petals arch outwards and have a pointed apex.
- Division 7: Fringed Tulips – Cup-shaped blooms with a fringed or spiked apex. Also known as crispa tulips. Several cultivars have fringes of a different color. Blooms in mid to late spring.
- Division 8: Viridiflora Tulips – Single flowers streaked with green (hence the name –viridis is Latin for green). Late spring blooming. A long-blooming novelty.
- Division 9: Rembrandt Tulips – Multi-colored, striped blooms that contributed to tulip mania in the 17th and 18th The markings are caused by a virus, so true Rembrandt tulips are no longer in commerce. There are modern tulips that are virus-free and have a similar effect.
- Division 10: Parrot Tulips – Ruffled, coarsely fringed petals combine with bright colors and stripes to give this group a distinct look. Bloom in late spring.
- Division 11: Double Late Tulips – Double or semi-double flowers that bloom in late spring.
- Division 12: Kaufmanniana Tulips – Multi-flowered tulip sometimes called waterlily tulips. Bowl-shaped blooms in early or mid spring. Long-lived. Foliage can be blue-green or streaked with brown.
- Division 13: Fosteriana Tulips – Large, single, bowl-shaped tulips bloom in mid-spring. Sometimes petal margins are variegated of bi-color. Also known as emperor tulips. Reliably perennial.
- Division 14: Greigii Tulips – brightly-colored flowers with mottled or striped foliage. These plants stay small, making them ideal for borders.
- Division 15: Species Tulips – this is a catch-all division for wild species, hybrids, and cultivars. Many are short-statured. Bloom time varies from early to late spring.
