Answer: Most tulips are single bloomers, but there is a small group of multiple bloomers sometimes called bunch-flowering. Some low growers in that group include the following:
Tulipa praestans 'Fusilier' with scarlet red blooms on 10-inch stems.
Tulipa praestans 'Unicum' has reddish/orange and white blooms and reaches about 8 inches.
'Toronto' and 'Georgette' are two other multi-flowering varieties.
Greigii hybrids are dwarf tulips, using growing 8-14 inches tall. There are many to choose from and they do well in northern climates such as yours.
