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’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!
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° 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
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.
- 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.

a friend gave me a hyacinth. it is in a vase with water with long roots. can I plant this in the ground? the long green stems are starting to wilt over.
You can plant the hyacinth outdoors now but it’s not going to rebloom this spring. Let the foliage die back. With luck it will bloom next spring in your garden.
I am having yard work done and have to move my Hyacinth. They are actively growing. Can I move them without killing them?
You can move them if you take care to dig deep so that you don’t damage the roots. Move the bulbs with soil around them.
I was given a Hyathins for Valentines Day in a pot and it says do not plant til fall so what should I do with it til fall. Can you help me? I live in Central Fla.
Hi ,
I bought my beautiful Hyacinth pot from grocery store while it was in bloom with three beautiful and fragrant blooms and they eventually and slowly dried up. I live in the zone 5B in an apartment but my apartment gets very bright sun. My hyacinths did not like too much sun so I kept them in indirect sunlight. Slowly the tips of the leaves are turning yellow and I do not see any more bloom, it is not even spring yet in Michigan. How much should I water them and whats the right amount of sunlight required for hyacinths? Also should I wait and see if it blooms again? Should I use any fertilizer or any plant food yet ? I love my plants and any help is much appreciated !
Thanks so much!

The hyacinths that you have were forced to bloom early. They will not bloom again this year. Let the plant die back and then you can save the bulbs to bloom again next year. Please see information about forcing bulbs at the top of this page and also read some of the questions and answers about how to save hyacinth bulbs on this page.
Do they only bloom once a yr ..
Have a pot of 3 hyacinths that are beautiful, but top heavy. They keep leaning over. How can I remedy this? Do they need lots of light or not? Thanks for your help.
It is in a light filled window, so I thought it must need more . However, the 3 blooms have not perked up. This has happened to me in past years. What am I doing wrong?
