Fosteriana Tulips - Emperor Tulips
The best thing about Fosteriana tulips is their simple airy flowers. Extra-wide petals unfold from tight buds, carried mid height (8", 20cm to 10" 25cm).
The original perennial tulips, they have been bred from Tulipa fosteriana, which grows wild in Central Asia. That's why they, and their descendants, Darwin Hybrid Tulips, are so good at naturalizing - spreading and multiplying year after year. Strong stems also help them stand up to strong winds.
They are also known as Emperor Tulips.
