I do like the bright colour combo in April. It makes me smile. Another aspect of this tulip that makes me smile is its strong inclination to return and multiply. Sandy soil might be an impotant factor.

Like most kaufmanniana tulips, this is an excellent perennial and naturalizer here (Boston Z6a), where few tulips last more than a year or two. (Tulips require a dry summer rest, and here we get too much summer rainfall for most tulips to perennialize. Summer irrigation can make tulips rot.)

It blooms with the daffodils, and is one of the earliest of tulips. Stems are too short to make first-class cut flowers, but it's an excellent garden performer.

I'm not fond of the color combination, but if you like it, it's a great plant. It even multiplies in the garden here.

All tulips are prime fodder for deer and other critters.
