About 10 years ago I purchased a handful of tiny bulbs labeled Tulipa clusiana, Lady Jane. I was told they were species tulips and their small size would be perfect for my rock garden. And perfect is what they were. Thriving on utter neglect they appear every spring unfurling their petals in the morning and closing at night. They seem more than content with the gravelly, dry soil and are a perfect companion for my Parry's agave.
One of their great advantages is that they do not require the same chilling as the larger tulips and are perfect for a climate which has milder winters. Furthermore they naturalize quite readily.The burgundy tipped stamens are distinct against the almost pure white petals.
By evening time the flowers close showing their pretty pink undersides. I have found the Lady Jane variety to be the most successful in my garden. Every year I am tempted to try others but have had little success.
