I planted 100 bulbs in 2011 and they did not bloom the following spring. They did bloom in spring 2013 but the flowers are so puny, I was very dissapointed with the show. I don't now if I have immature bulbs but this was just too much trouble for what I've gotten.

This is such a difficult region to garden in that I don't mind the pretty spring flowers of grape hyacinth At first, it was in the flower bed in the courtyard. I didn't know what this plant was for about two years after we bought this house (our second one in this High Desert region of New Mexico) because its blooming season was so short and its leaves look like fat grass. Then I began to notice that it came up in the lawn! After I identified its leaves in the fall, I began to dig it up to transplant into another flower bed. Every time, it sprouted up in the lawn again. Last fall, I thought I had gotten all of the grape hyacinths out of the yard, but one little clump is showing itself at this moment (late February 2012) out in the lawn. Earlier comments made here have been helpful because now I know I am fighting a losing battle. I am about ready to turn our small lawn over to herbs and flowers anyway because chamomile is taking it over, but that is another subject.

You'd better be really, really sure you want this plant because you will never EVER be rid of it. Planting this little cutie was the biggest gardening mistake I ever made. It is impossible to remove all of the teeny bulblets this plant makes. I planted it in a flowerbed in my back yard about 10 years ago, and it's now everywhere, front yard, side yards - there's no stopping it. I'm really surprised this is not listed as a noxious weed, at least in my area (Virginia). Do yourself a favor and think twice about planting muscari aremeniacum. I've spent the last several years attempting to eradicate it, without much luck.

I love this plant. I have to dissagree with the negative Colorado poster, at least for my area. Considering the winter we had here if anything this spring would have been ugly for this plant, but they are all beautifully green all the way to the tips, and I have never seen them as the other Colorado poster describes. That is sad to hear, I am just north of Denver and they are very healthy, abudant and fully green. It is one of my favorite plants, I just wish they bloomed longer.

Here in Colorado the foliage dies back and can be trimmed late summer, but these bulbs sprout new leaves in the fall instead of spring. Spending harsh winters above ground, the tips (and often half the length of the leaves) always wither to yellow and brown, so in the spring when the gorgeous flowers appear, they are sitting in a ratty bird's nest. I realize the bulbs could be dug up and replanted every year but what a hassle!
Although it's not a major complaint, I also wish they wouldn't spread so prolifically. Many of the new shoots don't bloom and end up looking like regular grass infesting the garden. And grape hyacinth can be tricky to remove if you ever decide to, because there are *lots* of small bulbs that are easy to miss, and sometimes they grow right up next to or under another plant that could be damaged by digging.
I have read so much about this little plant, and the one common word used by many authors is "invasive"! So what? So are dandelions and clover! This is such a welcome and refreshing sight in early to mid spring, I don't mind if it gets a little invasive. At least it grows carefree, blooms a bunch and brightens up the beds and lawn just when needed. From the information gathered, it comes to us from Armenia, therefore the species 'armeniacum'. The bees seem to love them as much as I do.
Blooms in April-May in my garden. A nice, sweetly scented flower, that even though it spreads rampantly, isn't in the way. If you decide to get rid of them, it is a daunting task. My information says it is hardy in zones 3-11.

This little plant has naturilized all over my 1/2 acre here just a few miles south of Kerrville, Texas. Came up and is flowering in late february. I have never planted any, they came with the place when I bought it. I didn,t recognize them and they have always been cut down with the weeds and grass in previous years. I plan to dig and pot them and see what the results are.

This is a very pretty bulb. It can be used as a border plant as it can spread rapidly. I bought 50 of these bulbs and they are all flowering now. It is a great sight. Other bulbs in my area which recieves very little rain come back stronger and more numerous year after year. pokerboy.

This plant reproduces two ways - many offsets develop, and self seeds freely as well - thus the "invasive" label, true, but a very welcome invasion. To increase more rapidly, dig clumps in midsummer after flowering as plants are then dormant, foliage dies down. Replanted bulbs will develop fall foliage and carry it through a severe winter, then flower in spring. I can't have too many.

Nice interplanted among taller spring-flowering bulbs, especially 'Angelique' pink tulips. They can be invasive (I spent a couple hours digging up clumps in my yard this spring), but when corralled in a bed, they make a nice, traditional sign of springtime.

Conical racemes of slightly fragrant, tightly packed, bell-shaped, royal blue flowers having a thin white line around the rim of each bell are borne on 6-9" scapes. Each bulb produces 1-3 flower scapes. Clumps of narrow, fleshy, somewhat floppy, basal leaves up to 12" long appear in autumn and live through the cold of winter. Flower scapes emerge in early spring. Good cut flower.
