Muscari Seed Planting: How To Grow Grape Hyacinth Flower Seeds

By: Bonnie L. Grant, Certified Urban Agriculturist

Winter doldrums are quickly banished by the appearance of the first grape hyacinth. While not as early blooming as crocus, these charismatic little bell flowers put on a hopeful show as sunlight makes a return appearance and spring bursts to life. Grape hyacinth seed propagation is not as easy or quick as growing the plants from mature bulbs but it is an inexpensive way to further expand your stock of these appealing flowers.

About Grape Hyacinth Seed Propagation

You would have to look far to find grape hyacinth flower seeds because the bulbs are generally sold for faster color displays in the garden. All you really need for Muscari seed planting is a spent crop of the plants in your landscape or your neighbor’s lot. Harvest the seeds from finished flowers that have dried on the plant and sow them after a chilling period.

It takes several years for the seeds of Muscari to mature enough to produce flowers. Due to this lengthy wait, most of us simply purchase grape hyacinth bulbs and install them in fall for spring blooms. Patient gardeners can save a buck by procuring grape hyacinth seed pods and removing the three seeds produced by each flower.

The ripe pods will swell once the seed is ripe and split open and it is an easy project to squeeze them out. Once sown, plants will result but they won’t bloom for 2 to 3 years. The delicate strappy foliage will still provide coverage for exposed soil areas and support moisture retention and weed suppression. In time, you will have a carpet of the tiny purple clustered flowers.

When to Plant Grape Hyacinth Seeds

There are two ways to plant grape hyacinth seeds. You can start them indoors or plant them outside in a cold frame. If you are starting plants outside and using nature to provide the required chilling period, fall is when to plant grape hyacinth seeds.

Muscari seed planting that takes place indoors can commence at any time after you have chilled the seeds in the refrigerator for at least three months. This mimics the natural chilling period the seeds would have received over winter.

Grape hyacinth freely reseeds itself, so some gardeners clip off the dead flowers immediately to prevent spreading plants. Avail yourself of this tendency amongst your friends and family and try growing your own grape hyacinth flower seeds.

Muscari Seed Planting

After you have taken the seed from grape hyacinth seed pods, you can plant them immediately in cold frames outside. Use well-draining soil in small pots or flats. Sow seeds on the surface of the planting medium with just a light scatter of soil to hold seed in place. Water lightly. Keep the soil moderately moist but not soggy, watering sparingly in winter.

Open the lid of cold frames in spring and let the little plants acclimate to outside conditions. You can continue to grow them in the cold frame or transplant them carefully the next spring. Start seeds indoors in flats after chilling in late winter to early spring. Cover the flat with a clear lid until you see the little sprouts, generally in 6 to 8 weeks. Remove the cover and keep plants lightly moist in a brightly lit area.

Transplant them after hardening off when they are a year old and soil is workable. In another year, you should see the vividly colored, tiny bluebells carpeting your garden beds.

How to Plant and Care For Grape Hyacinths

Grape hyacinth (Muscari spp.) dependably produces annual spikes of tight blue-purple flowers that resemble a bunch of grapes. The plants can thrive in U.S. Department of Agriculture hardiness zones 3 through 11 depending on the variety. M. armeniacum requires a winter freezing period to bloom, but M. paradoxum and M. aucheri types require minimal winter chilling and are able to withstand both cold and warm climates. Grape hyacinths grow from small bulbs that require minimal care and planting and can continue to thrive with little maintenance. Plant the bulbs in fall six weeks before your first expected frost to enjoy spring blooms.

Quick facts

These pretty blue ornamental lilies are amazingly easy to grow.

Grape hyacinths get their name from the tightly bundled florets that look like grapes at the tip of each flower.

There are many different types of hyacinths, but grape hyacinths aren’t related to them.

They have the grape clusters and they have a sweet-smelling aroma that’s especially prominent at night and during the early morning.

Each plant grows up to 12” and there are 1-3 stalks per plant. They sprout in early spring and usually result in colors that are blue and white.

Some hyacinths may also sprout orange, yellow, pink, and mauve florist.

These can be grown in hardiness zones 3-9 and are super easy to grow.

They’re a good plant for beginners that want to propagate from bulb or seed. If you don’t do anything but the bare minimum, they’ll likely reproduce so quickly you’ll need to prune them to keep them tidy.

These pretty grape-like plants are a stunning addition to any garden with their blue clusters and fragrance.
