Can forced hyacinths be planted outdoors? Yes!

Planting forced hyacinths outdoors after blooming
0

Flower spikes crowded with curling petals, best described as “locks”, carry a fragrance strong enough to scent a whole room. Native to West Asia, the hyacinth works as well in a winter pot indoors as in a border, where it is hardy down to 5°F (-15°C); give it light, humus-rich, well drained soil and it comes back.

The early blooming means the plant is spent when spring comes along. Will it survive when planted in the ground? YES!

Gardening: 

This fabulously fragrant flower is as perfect for the garden as it is for an indoor pot.

Hyacinth, a short story

A spent forced bulb can still go outdoors

Hyacinths are native to West Asia, Turkey, Syria and Lebanon. This flower has a powerful fragrance and is a symbol of peace, power and simplicity, too.

A poet, in his heyday, had compared the hair of his beloved to the elegant stature of hyacinths.

Today, the curly movements of petals on garden hyacinth flowers is best described with the word “locks”.

  • In gardens, gardeners often plant them directly in the ground in fall. They then bloom from mid-spring to early summer, depending on the variety and on the climate. Hyacinth does best in humus-rich, well drained, light soil (add sand eventually).
  • They like sun, but can nonetheless bear a little shade, and are extremely hardy, down to 5°F (-15°C).
  • Once leaves have withered, they are easily propagated. All you have to to is collect the small bulbs that will have appeared to the side of the mother bulb. Plant these smaller bulbs in fall. Their flowers will be smaller and less furnished than during the first year or two.

Forced bulbs: does planting them work?

Planting forced bulbs that have bloomed early is generally less successful.

They were forced in greenhouses, and often not survive the gap in the season cycle.

  • Ideally, they should be kept in the dark for a full year and a few months.
  • You’d only plant them in spring a full year later.
  • If you can’t store them that long, plant them in fall at the end of the first summer. Doing so results in about a 50/50 success rate (one in two survive).

To benefit from their intense perfume, plant hyacinths near your house, along walkways, under your windows, in your meditation garden…

Three ways to plant hyacinth bulbs, and what to expect

Whether a bulb has been forced or not changes both when you plant it and how likely it is to flower again. Here is what the article says about each case.

Three ways to plant hyacinth bulbs, and what to expect
Type of bulb When to plant What happens next
Ordinary garden bulb Directly in the ground in fall Blooms mid-spring to early summer, depending on variety and climate
Forced bulb, stored properly In spring, a full year later, after a year and a few months in the dark The recommended route for a spent forced bulb
Forced bulb, short storage In fall, at the end of the first summer About a 50/50 success rate, one in two survive
Small offset bulbs Collected once leaves have withered, planted in fall Flowers smaller and less furnished than in the first year or two

A forced bulb is never as reliable as a fresh one, but it costs nothing to try.

Hyacinth varieties worth looking for

Most hyacinths sold in autumn belong to a handful of long-established cultivars, each with its own colour and its own knack for either forcing in a bowl or settling into a border. Use this table to match the variety to the job you have in mind.

Hyacinth varieties worth looking for
Variety Flower colour Flowering time Best used for
Blue Jacket Deep navy blue, darker stripe Mid spring Borders and large pots
Delft Blue Soft porcelain blue Early to mid spring Forcing indoors and borders
Pink Pearl Deep pink, paler edges Early to mid spring Forcing indoors and pots
Anna Marie Pale shell pink Early spring Forcing indoors, containers
City of Haarlem Pale primrose yellow Late spring Borders, extending the season
Carnegie Pure white Mid to late spring White schemes, cut stems
Woodstock Beetroot purple Mid spring Pots and dark colour schemes
Jan Bos Crimson red Early spring Indoor bowls and bedding

Nice hyacinth bouquets

Cut stems give fragrant white, pink and violet bouquets

Hyacinth grows very well in our houses, balconies and terraces. It’s perfect for large pot arrangements.

Feel free to slice the stem and create nice, fragrant hyacinth bouquets. Most often, colors come in a range of white, pink and violet, with shades of blue.

Ever since hyacinths started selling hyacinths whole, with their bulb, quality has greatly increased. Cut hyacinths are increasingly appearing in floral art. Their appealing colors make them perfect matches for all seasonal bouquets.

  • Hyacinth bulbs contain needle-like calcium oxalate crystals that can irritate skin and cause the contact dermatitis known as “hyacinth itch,” so wear gloves when handling many bulbs for a prolonged period.
  • Stand the bouquet away from ripening fruit, since the ethylene that fruit releases as it ripens is known to shorten the vase life of many cut flowers, hastening wilting and petal drop.
