You're probably right Caroline, while some specie tulips bulbs look unique, others look quite similar.
A photo of a mixture of specie tulips in the Colorblends catalog was really appealing to me. I'm often suspicious of those photos of mixtures blooming together in other catalogs, but Colorblends specializes in formulating well timed blends, so it has had me considering trying a mix. They look very like a wildflower meadow.
