Having a small garden, I can't waste space taken up by Darwin hybrid tulips. I instead I look for species choices.
One I purchased last year and have had much success in my previous garden is: Tulipa clusiana 'Chrysantha'
Their narrow leaves and later blooming time is welcome in my garden. Once their flowers fade, I cut their stems down and I find planting them near another perennial camouflages their fading leaves late May. They stand shorter (10inches) and flower for a lengthier time than many of the Darwin hybrids.
The size of species bulbs are nearly a third of the Darwin hybrids. If you have limited space to plant groupings, this is your best bet!
|Darwin is about 2 x's taller.|
Here you can see the difference between the Darwin size and this Chysantha. My neighbour kindly gave me 5 bulbs last fall as a gift, and I couldn't say no thanks. I find in small spaces, Darwin's just take over. I will find them a new home later this month. ;)
