It is not hardy in cold temperatures and will not survive being frozen.If growing lobelia seedlings indoors, sow in late winter. If growing outside directly, sow seeds from early spring onwards. Lobelia prefers a well-drained, humus-rich organic soil that also retains moisture. The annual varieties resent growing in heavy or waterlogged soils, particularly in winter, which can be fatal.Perennial lobelia will die back at the first frost, dropping leaves and flowers and developing soggy stems.
