Beautiful blue hyacinth. The darker one in the picture is 'Crystal Palace'.

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.
