A very pretty hyacinth of a lavendar-blue color. The bases of the individual flowers are a pure aqua-blue upon very close inspection. Looks great with hyacinth Miss Saigon which blooms at about the same time.

*******************
In it's second year, the blooms are looser and not the tight bottle-brush shape. This is because the commercial bulb growers remove the flowers for several years before sale to build up the bulb's energy for a very dense and lush flower spike. I think the natural shape is just as beautiful and colorful, though.
