Where to use grape hyacinths
Muscari are ideal for edging paths, filling gaps at the front of a border and naturalising in grass. Scatter them in informal drifts and plant where they fall, then delay mowing for about six weeks after flowering so the bulbs build up for the following year.
They also suit pots. In a lasagne layered container, put larger, later bulbs such as tulips at the bottom and muscari near the top so they flower first. Whatever you do, choose free-draining soil or compost, as waterlogged ground rots bulbs more than cold does.
Frequently asked questions
Why are my grape hyacinth leaves coming up in autumn?
That is normal. Muscari often send up leaves in autumn, well before the flowers appear in spring, and the plants are not harmed by it.
How deep do you plant muscari bulbs?
8–10 cm deep and 5–8 cm apart, with the pointed end facing up.
Do grape hyacinths spread?
Yes, readily. Over a few years a small group will form a sizeable patch, which makes them good for naturalising under shrubs or in grass.
Combine muscari with tulip bulbs or daffodil bulbs, or browse more naturalising bulbs.
