Description
For horticultural purposes tulips are divided into the following groups, which are chiefly defined by their flower characteristics, stem length and time of flowering. By choosing tulips from across the groups you can have a sequence of flowering throughout spring. These replace the older divisions given in parentheses below.
Triumph Group (Division 3) – These single, cup shaped tulips grow 14-24″ tall with medium stem lengths and is the result of hybridization between cultivars of Single Early Group and Single Late Group. The flowers grow to 2 ½” across, in a wide range of colors, including dark purple to red, pink, yellow, or white, often edged or flecked with a contrasting color. Mid to late season flowering, and produce leaves that are 4 -14″ long. Suitable for bedding and good cut flowers
Select tulips cultivars and species based on hardiness zones. Most tulips require a long cold winter and dry summer and thrive in Zones 4-6. In Zones 7-8, fewer are adaptable. In Zones 9-10, they should be grown as annuals, and bulbs must be precooled at 40–45 degree Fahrenheit for 8-10 weeks before planting. Grow in fertile well drained, neutral to slightly acidic soil in full or afternoon sun. In Zones 7-10, choose a shady site or one with morning sun only.
