Did you ever think about giving your gardens a total makeover? My newest garden is probably ten years old and over the years it has had additions randomly tucked in here and there. I've been thinking about a change and I think I'll start with white. How about a Moon Garden where an old patchwork garden used to be?

'Hakkun' is very easy to grow in my garden. It's tough and healthy and does not need to be lifted for summer.
The bulbs do not break down into many small non-flowering sized ones easily, so it can remain in the same spot, without dividing for several years.

Unfortunately in my experience it blooms for a shorter time than most tulips.
It is very sensitive to heat, which makes the flowers shrivel, especially in full sun, even in my northern garden.
For that reason I think it is best suited for a place in semi-shade, unless you are fortunate enough to have it bloom while the temperatures are still low.
