I have grown 'Atom' for two years. I left the corms in the ground after the first season. We had the coldest winter temperatures in 20 years, down to minus 18 F, but with a heavy snowcover. All the corms survived, and the flowers more than doubled the second season. They are growing in a heavy clay-loam.

Wonderful, easy to grow glad with bright eye-catching blooms. Needs some staking but well worth it. The blooms are long lasting and heat tolerant. They are the first of a number of hybrid glads to bloom in my yard, right after my Byzantine glads. Highly recommended!

This was my first year with these glads, and I was amazed at just how gorgeous they were when they bloomed. The vivid color was a definite eye-catcher. But I need to tell their story:

I bought these bulbs from Gurney's and they were labelled as "Redwing Butterfly" Gladiolus. When they bloomed they were true to the photo and description on their website. However, when I tried to find them in plant files, they weren't there. BUT, I saw the photos of this "Atom" and they were exactly the same. After a post to the Plant ID forum, we all decided that Gurney's had made up their own name for these, since there are no Glads with the registered name of "Redwing Butterfly." So I am posting my photo here and I am calling them "Atom." =o)

A beautiful glad, much admired by all who saw it in the garden or in the vase. This was the first of six varieties in our garden to bloom this season.

This delicate, picotee-edged mini glad is breathtaking! Its tall, slim profile necessitates staking, though, if it's to survive to fully bloom to the top. Doesn't keep in a vase as long as regular glads...maybe 3-4 days.
