Muscari Propagation
Propagating grape hyacinths is so easy, it may not take any effort at all. You can propagate Muscari grape hyacinth from either seeds or bulbs.
Grape Hyacinth Seeds
When your grape hyacinth is done blooming, it will drop its seeds. By the spring, with any luck, these grape hyacinth seeds will have become their own plants. If not, you can propagate Muscari grape hyacinth by saving the seeds. Remove the dried seedpods from the plant, harvest the small seeds inside, and lay the seeds on a damp paper towel in a not quite sealed plastic bag. Place it in the refrigerator for a few months to allow them to sprout. You can then plant the seedlings in containers until large enough for the garden. Likewise, you can sow the seeds directly in the garden. Be aware, though – grape hyacinths reproduce very easily and quickly, meaning they could spread all over your garden (and yard) if you don’t pay attention to them. Try planting them near a brick or concrete walkway to create a border they’re less likely to cross naturally.
Grape Hyacinth Bulbs
If planting the seeds is not for you or if you simply want to transplant some grape hyacinths to another part of the garden, you can also propagate your grape hyacinth bulbs. Dig up a cluster of plants and carefully separate the bulbs underneath. They should actually come apart rather easily and there will likely be lots of offset bulbs to pick through. Choose the healthiest. Plant them where you wish, and they should start spreading from their new spots, giving even more of the pretty little plants next season.
