Valerie --
Lobelia cardinalis is native throughout eastern North America, from
Minnesota to Florida, so whoever said or thinks it wouldn't be winter
hardy in Zone 8 Britain must have been growing it under adverse
conditions -- or layed a stepping stone on top of it, or something. ;-)
The x Gerardi cultivars are even hardier, being the result of crossings
with the hardier L. syphilitica. Both species, and their many cultivars,
grow happily in good garden soil. The Lobelias do arise from the ground
later than other perennials which might sometimes cause a person to think
the plants didn't survive the winter. The winter-dormant roots need to
be mulched or otherwise protected from cold drying winds, but I don't see
any particular reason to overwinter the plants in water.
