Native to Eurasia, their blue flowers resemble bunches of grapes - hence their name. Actually, they are not Hyacinths but Lilies!
Be sure to order and plant some this fall if your garden doesn't have any yet.
I have planted other colors and other color combination varieties from mail-order catalogs over the years, but these are the ones that persist and multiply into the lawn.
Grape Hyacinths are hardy in zones 3 to 9.
Here they are under trees where the shade is very dense in the summer.
Still they do their wonderful spring-thing!
Plant them and just wait for them to naturalize and spread
all over the garden, greeting spring year after year.
