Species Tulips
The Wild Bunch
Species Tulips are the uncut diamonds of Tulips. Un-hybridized and uncultivated, many have a raw beauty and a tough constitution. Most are small. Some are tiny. Many, given the right conditions, will naturalize freely, just as they do in their native habitats in Europe, Asia and Africa.

Despite this, they are only now becoming widely available to gardeners - although they have long been coveted by collectors and enthusiasts, who tend to favor them over hybrids.

Unlike other Tulip Groups, Species Tulips are not defined by their flowering times, which may be anytime between February and May.

Species Tulip are also sometimes called Botanical Tulips.

Tips for Growing Species Tulips
In the wild, many of these Tulips are kept dry as a bone in summer. Make sure your soil is well-drained. Add plenty of sharp grit if necessary.
For a natural look, try scattering bulbs and planting them where they fall.
As with other tulips, leave dying foliage for at least six weeks after flowering.
To encourage naturalizing (spreading) don't deadhead the flowers.
Many Species tulips will naturalize in Southern US states such as Texas, where winters are too mild for hybridized tulips. Successful varieties include Tulipa clusiana (Lady Tulip), Tulipa praecod (Fire tulip), Tulipa saxatilis (Cretan Tulip), Tulipa sylvestris (Florentine Tulip) and Tulipa orphanidea (Greek Tulip).

There are beautiful red Species Tulips that I planted for my grandmother +25 years ago that come up every year. They are a bit shorter and a bit smaller-flowered than the other tulips I've planted but they are beautiful. They even keep pushing up among taller tulips. Really like them.
