Package of 10 bulbs. 
 
This late tulip is such a dark purple it is nearly black, and pairs well with  Alison Bradley and Black Hero. You can expect it to grow up to 24" tall in spring. 
 
In the fall, select a sunny spot with well-drained soil, and plant your bulbs at least 6" deep so they stay insulated through the winter but remain cool as temperatures begin to rise in the spring. Bulbs can be planted as close as 1-2" apart, and look best planted in small clusters. 
 
Bulbs can be planted in fall anytime before the ground freezes, but late October/early November is best in northern Illinois. 
 
Most tulips are treated as annuals, as they do not tend to return as strongly in subsequent years. After flowers finish blooming, you can pull out the entire plant, including the bulb, and compost or discard.
