Golden — visually appealing, subject to mildew if too close together
Rainbow — stalks seem more wimpy, less robust, but pretty in a bouquet. Inconsistent with mildew.
Fordhook — visually appealing “bubbly” leaves, but tend to shelter small spiders on under-side. LONGEST YIELDING. Subject to mildew and difficult to treat because of the textured leaves. Nice in a “bouquet” of varieties. Also easier to handle, not “floppy”
Giant Silver — high yielding, flatter leaves, useful thick stalks
Heirloom (Connie) — pinkish stems add variety. Seems to be mildew resistant?
Lyon — light lime green, very tender. Shorter lifespan.
