I inherited two of these from the previous owners of my house, They suffered neglect & bad placement but survived. I transplanted them immediately and they have taken some harsh winters and still come up better every time. These are real troopers and a definite indicator of spring in my region (NE). Did I mention they were amazingly fragrant also!

Fabulous color and scent! These were the second Hyacinth cultivar to bloom for me after H. Snow Crystal. They started blooming the second or third week in March here in zone 7a. They are in a very wet spot but looks like all bulbs bloomed no problem.

VERY fragrant! I didn't have full blooms, but that can be based on a number of factors. Just a great blue color that intoxicates the senses!
