I purchased Parrot Gladiola last year from an internet seller in Florida. They bloomed very well the first year, survived the winter with mulching, and as of May 1 are pushing up new growth. It was a mild winter with heavy snowfall. The lowest temperature was 2 degrees above zero F. Corms were planted both along building foundations and in the open garden. I am curious to see how they do over a colder winter, but have read that Gladiolus dalenii is Zone 6 hardy.

I live in zone 8a. I found this one glad growing in the field behind my house. I dug it up, moved it to my garden and it is doing beautiful! It is absolutely gorgeous. I will be looking for more! The flowers also seem to last longer than most glads - nearly 3 weeks!

Beautiful plant that grows wild in this area. I found mine growing by the roadside. I found a web entry that said it was 'rare' and they were charging $20 per plant...I found other websites that said it was noxious and considered a weed because it can become invasive. However, I didn't see it as being any more invasive than any other gladiolus.
I love the bright orange and yellow bicolor flowers with the yellow speckles in the orange. The blooms are smaller than the commerical glads, but the color is so showy, that it just jumps out at you when you see it by the road. and it is very hardy in the SE Alabama/ SWGeorgia heat.
