Perfectly Charming Spring Standby. The Grape Hyacinth or Muscari is a spring standby no garden should be without. Apart from being perfectly charming when planted on their own, these attractive plants form the ideal setting for showy Tulips, Daffodils and other spring-flowering bulbs. Best of all, they’ve got real staying-power and can be left in the ground or lifted and stored for next year. But if you think you knew your Grape Hyacinths, you should take a peep at Farmer Gracy’s selection. We’re ready to bet you’ll find a few surprises!
