Hyacinth are one of the most popular bulbs for indoor flowers. These spring-flowering bulbs give forth in a burst of color that lasts for about two weeks—and better yet, they’re delightfully scented. Most hyacinth bulbs for indoor use are forced to flower.
Although you can get forced hyacinth to rebloom, they never seem to recapture the magic of their first bloom, so most people usually discard them after their bloom. If you buy naked bulbs, as opposed to blooming plants, you’ll have to provide several months of chilling to coax the flowers out.
- Light: Bright.
- Water: Keep the potting media lightly wet, but not soaked. If you’re growing in water, as in a decorative vase, only let the roots dangle into the water.
- Temperature: Keep them cool during the growing season to prolong the bloom. Recommend temps range from about 45 degrees F to 65 degrees F.
- Soil: Loose, well-drained potting mix. They can also be grown in pebbles or suspended over a small vase of water.
- Fertilizer: None is needed, but a little liquid blooming fertilizer will lengthen the bloom.
Not recommended. Throw away spent bulbs and get new ones for next season. It’s true that you can store hyacinth bulbs and force a new bloom, but the plants will never regain the same vigor or set out pups for new plants.
Most hyacinths are purchased in their decorative vases. If you’ve forced the bulbs or purchased pre-chilled bulbs, you can start them in smaller containers then shift them to decorative containers or vases once the leaves have begun to grow.
The standard hyacinth is a Hyacinth orientalis hybrid—and there are many. Pick your hyacinth based on its color. Popular varieties include pink, blue, and purple.
The process of forcing a spring bulb like a hyacinth is time-consuming and requires keeping the bulbs chilled for months at a time. At the end of the process, you’re rewarded with a plant that lacks the beauty of its first bloom (forced bulbs are deprived of nutrients).
With so much work and so little reward, most people simply discard hyacinth at the end of the bloom or move them to an inconspicuous corner of the outside garden. During blooming, keeping them cool will prolong the bloom. Consider moving them at night into the coolest room and displaying them during the day.
