Is grape hyacinth invasive?
Because muscari, or grape hyacinth, are vigorous growers, they can become invasive in the right circumstances. These plants propagate both by division and self-seeding, so you'll see the bulbs multiply underground while the plants produce seeds that fall to the soil. If you're concerned about grape hyacinth overtaking the garden, be careful to maintain your plants yearly. Deadhead the flowers after they've bloomed, and pluck any plants-and bulbs-that grow outside of your desired area.
Do grape hyacinths come back every year?
Grape hyacinths are perennials and do come back year after year. They fill in spaces and naturalize well. If your grape hyacinths are becoming too crowded after a few seasons, you can thin them via division and replanting.
Are grape hyacinths really hyacinths?
What's the difference between a hyacinth and a grape hyacinth? These plants are actually unrelated, but they're both springtime bulbs with excellent bloom times. Grape hyacinths are not really hyacinths, but are named for their larger look-alikes. True hyacinths have a strong springtime fragrance, but grape hyacinths do not smell like true hyacinths.
When should I plant grape hyacinths?
Grape hyacinths should go into the ground in fall, after the ground has cooled. Like other springtime bulbs, muscari need a cool period before blooming in spring. These bulbs are quite easy to plant-they only need a few inches of space each, and can be planted in wide swaths.
