Gladiolus hybrids are not reliably perennial locally. They might not be reliably perennial anywhere. I had believed that they could be so where they get more winter chill, but chill does not seem to help. I have been told that they are no more perennial in Pennsylvania, Oregon or Oklahoma. When I grew them many years ago, only about a third survived to bloom for a second season. Of that third, only about a third survived to bloom for a third season. This is one of many reasons why I am so ‘glad’ about perennial Gladiolus papilio , as well as Watsonia species, from Tangley Cottage Gardening. Although, strangely, a few hybrid Gladiolus survive.
1. Watsonia X pillansii ‘Coral and Hardy’, just like the Gladiolus papilio, was a gift from Tangly Cottage Gardening of Ilwaco in Washington. I learned that it blooms in summer.

2. Lilium of an unidentified cultivar is finally finishing bloom. Obviously, it is irrelevant to Gladiolus. It just happened to be so pretty precisely as I was in need of a sixth picture.

3. Gladiolus is mostly finishing bloom now. These few are blooming a bit late. These are merely the common hybrid sort that someone purchased from a retail nursery years ago.

4. Not only have a few of the Gladiolus hybrids been surprisingly reliably perennial for a few years, but this pastel yellow cultivar has actually multiplied, from one bulb to a few.

5. This Gladiolus hybrid blooms annually also, but unlike the pastel yellow cultivar, does not multiply. This and one other just like it are the only two, with neither more nor less.

6. This purple Gladiolus hybrid does the same. It would be nice if it could generate a few copies. Since it is the only specimen here, and might be fragile, I will not tamper with it.
