Other Botanical Tulips

This is a "catch-all" class for just about every other type of tulip. In particular, it includes wild tulips. Altogether there are about 150 different species of wild tulip, which grow in an area that runs roughly from Portugal to Central Asia. However, most of these are not cultivated for gardens. This class includes species, variants, and hybrids derived from these wild tulips which are cultivated and sold commercially. To illustrate: a wild species of tulip might be called something like Tulipa batalini or Tulipa humilis. If someone has developed a cultivated variant, it might be named, for example, Tulipa batalinii Bright Gem or Tulipa humilis Persian Pearl.
Since the tulips in this class are wild, or close to wild, they typically naturalize extremely well (i.e. come back year after year and gradually multiply). As most tulips in this class are fairly short, they are absolutely ideal for rock gardens and containers. They also look wonderful when planted in large, one-colour flower beds ("drifts").
The following chart shows 10 of the several dozen wild species which are commercially available. Unless otherwise noted, all of the following species are hardy in zones 3 - 8, and should be planted at a depth of approximately 4 - 5" (10 - 12 cm) . A few species have a fragrance; I have indicated which ones by putting an asterisk (*) after the name.
