Muscari Bulbs for Blue Flowers

Muscari bulbs (grape hyacinths) add a lovely blue colour to the spring garden. The little bulbs bloom briefly in the late spring, and then they die back for the summer.  Their leaves often appear in the late fall again. These are tiny bulbs that can be planted close together to make a good show. Muscari are hardy in  a cold climate, and usually return each year, with the exception of one mysterious group in my front yard.

Muscari ‘azureum’ flowers are a very pretty shade of  light blue. This is a new clump, planted last fall, and the flowers are a little sparse still. I hope they like this spot, and fill in the group more next year.

The clusters of Azureum open from the bottom. The top of these blue flowers are still tight, while the bottom are opening with frilly edges.

In Muscari armeniacum ‘Blue Spike’, the little clusters are extra thick, giving a frilly appearance. The texture of the blue flowers is very appealing. They appear to be twice as large as other Muscari, and show up better, for such a small bulb. The larger flower clusters are more noticeable across the garden.

Muscari armeniacum ‘Blue Spike’ starts blooming a little after M. azureum. They bloom for about 3 weeks, and then die back for the summer. These petite bulbs work well next to perennials or shrubs that will fill in, after they fade away for the summer. I have some in between some daylilies and a royal fern that is always very slow to come up. The royal fern is the last plant in my garden to emerge, so the Muscari have lots of room still.

In the above photo, you can see how a group of Blue Spike makes a nice show, with the thick blue flowers, and good amount of blooms. This group was planted last fall. For some reason, one clump of Muscari in the front of my house has disappeared this year, after blooming there for the last five years. I’ll replant the Muscari bulbs this fall, probably with Blue Spike.

You can see how they look as a larger river of blue in spring , after I planted more Muscari armeniacum ‘Blue Spike’ in the fall.

I like the light blue of M. azureum, but particularly like the showier flowers of Blue Spike that are double the size of the regular grape hyacinths. Muscari are the last of the little blue bulbs to bloom in my spring garden. They follow after the tiny Scilla and Chionodoxa, and just as the early perennials, with their larger display start to bloom everywhere.

  1. I can experience spring all over again with you. Here in Tennessee we have been having nights in the fifties in June….quite cool. My daylilies are trying to bloom but they need heat to really expand properly. I must move them to all sun unlike Zone 8 where a little protection was appreciated by some.

    1. MNGarden, there are many spring blooms now, and the early summer ones should be hot on their heels.
      It takes a bit of experimenting to find the perfect exposure for some plants, especially from one zone to another. Do you find that you can grow a wider variety of plants now, or fewer?

    1. Spot of Gardening, blue can go very nice with pink. In a sunnier area of my garden, I have some blue flax next to some pink carnations that I like together, and some blue lobelia near a pink peony that I like.

    1. Racquel, The blue Muscari would look great with yellow Narcissus, especially miniature ones that wouldn’t overwhelm them. The Azureum are a nice light blue. They would probably look good next to a light yellow.

    1. Joanne, yes, the little bulbs are the pretty introduction to the flowering season. Now, the Viburnum has its white blooms overhead, and other perennials are opening or budding. I love walking around the garden to see which buds are opening.

      Joy, the Muscari have an intense blue like the squills. I have seen photos of giant patches of them, like rivers, with taller bulbs rising above that are breathtaking. If I had an acreage, I would love to do something like that. Mine are more puddles than rivers right now.

  2. Hello there again !
    I love these little guys plus squill ? I may have the wrong name .. coffee hasn’t done its job yet this morning, haha.
    These touches of blue in the garden are beautiful with my yellow bulbs especially .. you have reminded me to order these little guys as well now , thank you : )

  3. How fun it is to look at your muscari and remember that it wasn’t all that long ago that I had them blooming, too. I, too, hope the Azure fills in next Spring!! :-) Happy Days!

    1. Shady Gardener, this section gets morning sun in the spring, so they might fill in quicker than some of my other more shady patches. I put in 30 or 45 of the azureum, and planted them fairly close, but it will help if they make a few new ones in between. I might extend the group next fall, since they seem to have done well, and I like the colour.

  4. I haven’t seen some of those varieties of muscari before. I have the common dk blue and a few white (that I keep losing somehow!) I’ll keep my eyes open for the lighter shades.

    1. Muum, the Blue Spike are very sturdy, and it would be harder to pack any more petals onto the cluster. They make a nice group. The azureum bloomed first, their flowers starting before the Scilla.
