VARIETIES PLANTED:
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?
