You've accomplished your goal already: WOW! That is going to be so spectacular. I have a flowering crab sitting in the middle of a square area of lawn and I've been toying with the idea of doing something there...giving it a "petticoat" of flowers underneath,...it would make it so much easier to mow around, if I did not have to get under the tree.
Do you have other perennials in mind for the area once the tulips have faded? The problem I have here with tulips is our weather...we usually go from very cold winter temps straight into very hot late spring/early summer temps. Most tulips bloom and melt within days and it doesn't seem worth it to buy/plant them.
