Planting, Growing, and Caring for Hyacinths

Catherine Boeckmann

Ahhh! The scent of hyacinth is intoxicating in springtime! And who can resist the tiny blue Muscari? Learn more about planting these spring-flowering bulbs as well as caring for the pretty pastel flowers after they bloom.

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鈥檚 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 鈥渉yacinths鈥 for simplicity鈥檚 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!

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.

Please note: Most hyacinths grow in zones 3 to 9. They must have cold temperatures of 40掳 to 45掳F (4掳 to 7掳C) for at least 12 to 14 weeks. If temperatures in your area do not get this cold, you鈥檒l 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

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掳F (7掳C), for at least ten weeks to allow roots to develop.
  • When shoots are about 1 inch long, increase light and temperature gradually.
  • Water carefully, avoiding 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 鈥渨et feet.鈥 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.

Types

  • Hyacinth orientalis 鈥Blue Jacket鈥: 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 鈥楥ity of Haarlem鈥: A wonderful heirloom variety that’s been popular since the late 1800s. The flowers are soft, primrose yellow, maturing to creamy white.
  • H. orientalis 鈥楪ypsy Queen鈥: 鈥楪ypsy Queen鈥 is an heirloom hyacinth with salmon pink petals with peach and buttery-yellow highlights.
  • H. orientalis 鈥楯an Bos’: Intensely fragrant, this award-winning hyacinth has fuschia-pink florets that are tightly packed into large flowerheads.
  • H. orientalis 鈥Miss Saigon鈥: With a deep, rich purple color, this fragrant hyacinth is covered with starry, violet florets. Gorgeous!
  • H. orientalis 鈥楶ink Pearl鈥: Rose-pink flower heads turn heads with their cotton-candy sweetness; 鈥楶ink Pearl鈥 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.

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掳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.

Wit and Wisdom

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鈥攃alcium oxalate鈥攊s 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.

Pests/Diseases

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

I purchased a Hyacinths from Aldias that is in a glass vase with water. There are roots going down to the bottom of the vase. There are 2 tiny bulbs attached to the bottom/side of the original bulb with new leaves growing from these small bulbs.

The problem is that the large bulb is having trouble staying in the vase and keeps falling out as the small bulbs are pushing up on the large bulb.

How can I save all 3 of these bulbs?

Remove the plant from the vase and place it in a bigger container with water or plant it in a container with soil.

My hyacinth was doing very EILL up until a few weeks ago, when I noticed that the emerging petals were turning brown and dry although the rest of the plant was, and still is, green and healthy. It got worse and worse and I didn't know what was going wrong, but this evening I touched the centre petals, which were now all completely dry and brown (almost like a pine cone in shape, colour and consistency) but the entire section fell off into my hands. I too, the plant to get a better view and saw grey fuzzy mound in the centre of the plant, which I removed, and I left the rest of the healthy plant back in its place. My question is this: is there any way that the plant can flower again next year' or is it completely dead? Also hat can I do to prevent this happening again? Thanks so much!

I got mine hyacinth flower with glass jar with water in it.can I take it and plant in soil now my bulb doesn't to stand in jar no more it keeps falling over.

Please see other questions and answers on this page about growing hyacinths in glass jars or vases and then storing or planting the bulbs to have blooms next season.

I have the same question as Mary Cobb. I did my best to read questions and replies. I went all the way to April 2014! Please help, now I'm overwhelmed with what to do with this beautiful, fragrant flower that I bought in a hourglass shape vase, the bulb is supported out of the water. Lots of long roots. But it is tipping way over. Anything I can do ? Right now I'm trying to prop it. Also, I don't have a place to plant outside. How do I keep it as indoor only plant. Do I try to find bigger vases to support them in water? Thank you.

You can move the hyacinth to a bigger vase with water or plant it carefully in a pot with soil. The flower will fade and the leaves will turn brown. When the plant has died back you can remove the leaves and lift the bulb. Let the bulb dry and then store it in a paper bag. For it to bloom again it needs to be chilled for 8 to 10 weeks and then planted in fresh soil.

I recently received three hyacinth plants already flowering. Can I transplant each bulb into its own pot and continue to grow in the house?

I have a violet hyacinth that I got one month back in a pot. I kept it outside and watered till it bloomed. Our weather her is about 20 degC at night and can reach 30 during the day. When the flowers turned brown, I cut the stem about 2 inches. From that day, the stems are not growing but the leaves are continuously growing to an extend I had to get a bigger pot ( leaves are 1 foot long). Should I keep them in the same condition? Or should I try something else?
Further, I got another three white a honey bees loved them. Just waiting to see if any flowers were pollinated or not!!

Hyacinths need a cold dormant period to be able to produce new blooms. Stop watering and let the leaves turn brown. When the bulb is dry you can remove the leaves and store the bulb in a cool place (refrigerator works) for about 8 weeks. Then you can plant it in soil again and start over. See more questions and answers on this page about how to store bulbs and how to get them to rebloom.
