how many bulbs did you originally start with, Roland??
Of the Queen of the Night? I think two dozen. But that was over a decade ago. I remember they fit on the right (south) side of the steps - where the variegated grass (and calla lilies) now are located.
I remembered when I was a child that my grandparents had tulips in their garden (supposedly) brought back from Holland after WWII (my dad & his 3 brothers participated in the European theatre) - and there was one, yup, just one 'black' tulip. Bryan made a point of getting them for me.
