    • This is the first year I grew the Serendipity. Other reviews say they are cute little plants...mine is at least 2 feet tall and has giant blooms on top. I love them..I only purchased 5 bulbs but will definitely get more in the Fall. Are the seeds collected from the blossom? I thought it was just a "bulb". At any rate, they are the star of my small garden, So far deer and chipmunks have not touched them!

    • Totally happy with this plant because it is just as beautiful as pictured. In less than one month, it is blooming with several bright purple globes and the pollinators love it!

    • Very cute little plants. They didn't reach their full potential this year but did produce a couple of flowers. The biggest thing for me is that they withstood our Texas heat and didn't die! I'm looking forward to next year to see how they perform.

    • VERY pleased with this plant. I'm in zone 5b (North Colorado Springs). This is the most challenging place I've ever lived for growing things ( it isn't unheard of to have a 50 degree swing in temperature in just one day...during each season). I ordered two plants on 11 Jun 2021; delivered 17 Jun & in the ground by the 23rd (full sun). Full of blooms within weeks. Had a rough 2021 winter (in the negatives for a week+ stretch) but these beauties have returned nicely. Ordered another plant for 2022 in addition to starting seeds I saved from the 2021 blooms (they are doing well).

    • I am super Obsess with these allium, and the way they start giving me a beautiful border. I couldn't help but to but more for the new secret garden , for my ground they settled so well and reproduced so fast i was able to even divide already, less then a yr in. the new one I was able to do the same before placing them in the ground. a must have in the garden.

    • Zone 8b (Seattle suburb) LOVE this little onion plant. She is absolutely adorable. I planted these between white drift roses, walkers low cat mint and earth angel roses, and it looks absolutely divine! Great plant, I hope she reblooms next year. Too bad I can't attach pictures.

    • This was an excellent plant to add to my garden this year! They arrived in full bloom, and stayed in full bloom until October. We were able to save a lot of the seeds in hopes that will be able to grow some next year. I highly recommend these cute little plants.
