On a related note, I could use some help IDing a hardy gladiolus. These were cheap Dutch bulbs from a local supermarket, labelled *nanus*'Sabrina', but don't at all resemble photos of several dissimilar cultivars sold as that. They're short, bloom in late summer, and appear fully hardy here with no snow cover. The background color is somewhat brighter yellow than my terrible photo shows. http://flickr.com/photos/58877781@N00/… Sean Z Zone 6a SE Michigan
