Thought these were very pretty
But of 100 bulbs received and planted only a handful came up. Very puny. Still pretty but don't look like picture.
Don't buy these
Planted 2 packs a few years back. Less than a quarter came up with no blooms. Last few years there were about 20 flowers, all yellow. The blooms are under whelming and relatively short lived. This year I removed them and will plant something else in the fall.
Didn't Come Up
I was very disappointed in these. I didn't have any of these come up this spring. Picture looks great and was very excited for these. Sad

Disappointing performance
Verified Buyer
These did not perform as well as I had hoped. Only about half of the ones planted produced a flower.

Blends in
Verified Buyer
Much smaller than expected. Nice addition but shows weak.
Slightly disappointed
Verified Buyer
Not sure if picture was misleading but I wasn't able to achieve the massing effect. Followed directions and so forth. Maybe next year?
Not like the picture
Verified Buyer
Only a few of them came up. There was hardly any yellow and the allium were not circular, looked like they only bloomed 1/4. The stalks were very slim and short as well.
Very Disappointed
Verified Buyer
I planted the complete Allium Duet in one area for a statement. Not only were there no blooms, there were no plants that came up. Very disappointed. I also ordered and received several packages of Eremurus Shelford Hybrids Mix. I shared with my daughter, sister and niece to have a variety of areas to compare. None of the roots came up for any of us. My Niece is a Master Gardener, sister is well known for her gardening skills and my daughter and I are no slouch to growing things. But, we were all unsuccessful in getting a plant to even come up.

1/4 came up and flowered
I was skeptical with the bad reviews but thought I would try them. I got some that came up and bloomed but most didn't. So they were very sparse. Everything else I oreeed last fall came up great.
Very Disappointed
I bought these last year and not a single one sprouted, let alone bloomed. I'm very disappointed.

- Q
The bulbs are very tiny. About 1/2 inch. Is 4 inches too deep to plant?
- Asked by Pam
- Verified Reply - AngelaI would plant the bulbs about 3 inches deep.Was this answer helpful to you
- Q
I purchased this last year and planted them all together. The yellow flowers are all blooming well but not one blue one. Does it take more time for them? I thougjt they would bloom at the same time.
- Asked by Cinda
- Verified Reply - AngelaYou should at least be seeing foliage from the Allium caeruleum. If there is no foliage, them something has gone wrong with the bulbs. If there is foliage, they should be sending up flower stalks any time now. The two varieties should overlap in blooming most years. Some of it depends of the weather conditions. If your bulbs are not growing, please contact customer care for help with a positive resolution. Any agent will be happy to assist.Was this answer helpful to you
- Q
How long does the greenery remain after the flowers have finished? Asking for placement compatibility with other plants of similar size, but different bloom periods.... competition for visibility..... Just being greedy with my viewing options. :)
- Asked by Flower Puff
- Verified Reply - AngelaThe Allium foliage will actually begin to die back when the plant blooms. Foliage should be allowed to die back completely rather than being cut. Like daffodils, it's a good idea to plant something in the front to hide the browning foliage. It may take 4 to 6 weeks for them to dry up completely.Was this answer helpful to you
- Q
Do these bloom after the purple sensations? I planted both and the purple have bloomed these have not at all.
