Ahhh, the scent of hyacinths in full bloom—springtime’s little perfume bottles! And don’t even get us started on the tiny cobalt-blue Muscari, sneaking in like miniature bells of joy. 

Whether you’re planting them in pots, borders, or bouquets, these fragrant spring bulbs are sure to make your garden (and your nose) very happy.

About Hyacinths and Grape Hyacinths

  • Hyacinths (Hyacinthus): Originally a pale blue or violet flower, hyacinths now come in a rainbow of colors, including lilacs, pinks, white, cobalt blue, cream, apricot, and even a blood-red hue. Each hyacinth bulb generally produces one flower stalk that stands 8 to 10 inches tall. The hyacinth’s loose-to-dense racemes (clusters) of strongly fragrant flowers may be closely packed single or double flowers.

  • Grape hyacinths (Muscari) are not directly related to true hyacinths, but also bloom in mid-spring and have the same care requirements. This tiny wonder has small clusters of bell-shaped, cobalt-blue flowers.

Note: This page will refer to both Hyacinthus and Muscari plants as “hyacinths” for simplicity’s sake!

As hyacinths are one of the first blooms, they look best at the front of a perennial garden, near the front door, along a walkway, or in mixed borders. These beauties are also a great choice for pots and planters. Hyacinths make wonderful cutting flowers, too, and look stunning in bouquets. As the flowers are famous for their fragrance, you can bring the sweet scent of spring inside!

Please note: Most hyacinths grow in Zones 3 to 9. They must have cold temperatures of 40° to 45°F (4° to 7°C) for at least 12 to 14 weeks. If temperatures in your area do not get this cold, you’ll need to pre-chill the bulbs in a refrigerator before planting them outdoors. 

Warning: Hyacinth bulbs (and daffodil bulbs) contain a substance called oxalic acid, which can be irritating to bare skin. Use gloves when handling these bulbs for extended periods.

Planting

Where to Plant Hyacinths

Choose a planting site that gets full sun for the largest blooms and straightest stems. The bulbs are tolerant of partial shade as well.

Grow in loosened, moderately fertile soil that drains well. Avoid planting low areas where water collects; hyacinths will rot in wet soil! Before planting, loosen the soil and work in 2 to 4 inches of compost or bonemeal for fertility.

When to Plant Hyacinths

Like other spring-blooming bulbs, plant hyacinth bulbs in mid-to-late autumn, any time after your first fall frost and before the ground freezes.

How to Plant Hyacinths

  • Plant hyacinth bulbs 4 to 5 inches deep. Space bulbs 5 to 6 inches apart (grape hyacinths can be 2 inches apart). At the northern limits of their hardiness (USDA Zone 3), plant 1 to 2 inches deeper to ensure winter hardiness.
  • Dig out a larger area if you wish to plant five or more bulbs simultaneously. Hyacinths look beautiful in groupings of five to nine bulbs. Grape hyacinths also look best in masses and loose drifts.
  • Set the bulb in the hole with the pointy end up.
  • After planting and covering with soil, water thoroughly.
  • Apply a 1- to 2-inch layer of mulch around the plants to discourage weeds and disease.
  • If you are transplanting, water sparingly and then do not water again until flower buds appear the following year.

Forcing Hyacinth Bulbs Indoors

  • Hyacinth bulbs may be forced into early growth for indoor display in the winter. Plant them with the tips just showing, in soil-based potting mix in containers with drainage holes.
  • Keep in a dark place at temperatures above freezing but no higher than 45°F (7°C), for at least 10 weeks to allow roots to develop.
  • When shoots are about 1 inch long, increase light and temperature gradually.
  • Water carefully and avoid wetting the shoots or waterlogging the soil. Soil should be moist, not wet.
  • After flowering, forced hyacinths may be transplanted into the garden, and they will flower again in subsequent years.

Growing

Caring for Hyacinths

  • Do NOT overwater hyacinth. They do not like standing water or having “wet feet.” Water ONLY if the soil is dry at a depth of 3 inches. If it is dry at that depth, it is time to water.  
  • Water deeply at the soil level, not from overhead or with a sprinkler which encourages disease. Lay the hose end next to the plant, turn the hose on low, and water for about 30 minutes or until the soil is moist. A soaker hose turned on low for a few hours will cover a larger area effectively.
  • With the organic matter and mulch, you do not need to fertilize. However, it’s OK to sprinkle a commercial organic fertilizer over the soil.
  • Protect container-grown plants from excessive winter moisture by covering them or moving them to a sheltered area.

Harvesting

What to Do With Hyacinths After Flowering

Outdoors

  • After your hyacinths have finished flowering, remove the blooms, but don’t remove the foliage. The bulbs need their leaves to gather energy for next year’s blooms. The foliage will die back naturally at the end of the spring season. Remove when the leaves have turned brown to help prevent fungal diseases.
  • Hyacinth bulbs can remain in the ground throughout the year in most planting zones. If you live a warm climate where temperatures do not get below 60°F, bulbs should be dug up in the fall and refrigerated in a cool, dry area for 6 to 8 weeks. Hyacinths require a period of colder weather to bloom. 

Indoors

  • Hyacinth bulbs that have finished flowering indoors can be transplanted into the garden. After flowering, they need time to gather energy for next year’s blooms, so they should not be placed directly into storage.
  • After their foliage dies back outdoors, hyacinth bulbs can be brought indoors and stored in a cool, dark, dry place until the fall or winter. 

Pests and Problems

  •  Bulbs are prone to gray mold and bulb rot when kept too wet.

Types

  • Hyacinth orientalis ‘Blue Jacket’: One of the great blues of the flower world. These award-winning hyacinths display big columns of royal blue florets with crisp white edges.
  • H. orientalis ‘City of Haarlem’: A wonderful heirloom variety that’s been popular since the late 1800s. The flowers are soft, primrose yellow, maturing to creamy white.
  • H. orientalis ‘Gypsy Queen’: ‘Gypsy Queen’ is an heirloom hyacinth with salmon pink petals with peach and buttery-yellow highlights.
  • H. orientalis ‘Jan Bos’: Intensely fragrant, this award-winning hyacinth has fuschia-pink florets that are tightly packed into large flowerheads.
  • H. orientalis ‘Miss Saigon’: With a deep, rich purple color, this fragrant hyacinth is covered with starry, violet florets. Gorgeous!
  • H. orientalis ‘Pink Pearl’: Rose-pink flower heads turn heads with their cotton-candy sweetness; ‘Pink Pearl’ is a favorite for spring containers to add a pop of color.
  • Muscari armeniacum: This grape hyacinth has small and delicate cobalt-blue flowers that look gorgeous when planted en masse.

Wit and Wisdom

  • The Victorians revered hyacinths for their sweet, lingering fragrance, and carefully massed them in low beds, planting them in rows of one color each. In general, hyacinths are said to symbolize playfulness, sport, and rashness, though their meanings are color-dependent. Learn more about the meanings of flowers.

Are Hyacinth Bulbs Poisonous to Cats and Dogs?

Yes, hyacinth bulbs are poisonous to pets. Many spring flowers, such as hyacinths and daffodils, contain a compound that may cause stomach and respiratory issues and skin irritation. This substance—calcium oxalate—is most concentrated in the bulbs, but is also found in the foliage and flowers of the hyacinth plant. Keep hyacinths out of reach of curious pets and children, and wear gloves when handling hyacinth bulbs for long periods of time.

The one upside to the hyacinth’s toxicity is that common garden pests, such as squirrels and groundhogs, often aren’t as tempted to eat your hyacinth bulbs!

Will Hyacinths Bloom Again?

Yes and no. Hyacinths bloom just once yearly (in the spring), but they will happily bloom again in subsequent years if provided with the proper care. They are a perennial plant.

It'll be too late, now. I read somewhere that the roots are very fragile, so once you've taken it out of the soil, do not put it back. Let it brown the way it is then clip the leaves and put it somewhere dark and cold (not freezing) to hibernate. It'll already be doing some emergency shut down because some of the roots were probably broken while you took it from the soil.

I have 3 Hyacinth plants just cut the flowers back and put the pots on my front porch do I need to keep watering the plant? I live in texas and I would like to replant them in the ground can I do that while the plants are still green? If not when can I replant them in the ground can the bulb be stored in a paper bag in the refridgerator?

If these were "forced" bulbs that you acquired in or near bloom outside of their normal season (say, at Easter), re-bloom is not likely, at least according to our sources. You might get foliage but probably no flower. But you can try it: When the foliage yellows cut it off, then lift the bulbs. Shake or brush the heavy dirt off of the bulbs. Most sources indicate that storing them in a paper bag is fine; some say a refrigerator is too humid and a "crisper" drawer is better.

I have a fenced yard, but know that is a minor hurdle for a full grown deer. Will planting hyacinth attract them to my yard?

Though there is no such thing as deer-resistant plants, hyacinth is not one of their favorites and usually on the "Seldom Damaged" lists.

First year for hyacinth and they're beauties. After they're done blooming and aging in their outdoor pot on the patio, can I leave the bulbs in the pot and dirt then store in a shed -- or do I need to remove the bulbs from the dirt? I live in the Pac NW and it gets humid, so guessing they'd stay dryer in their pot w/dirt. Saw the note to repot them every 3 years, but this is their first Spring. :-)

You can leave the bulbs in the pot after blooming and the leaves die and then put the entire package into the shed. A requirement for rebloom is a fairly sustained period of cold (some sources suggest around 40°F to 50°F; certainly in snow country, it can get colder than that). Failure to experience that chill is likely to result in malformed plants. Good luck!
