Most of perennial Lobelias are not 100% frost hardy and will need protection during the winter months by covering the soil with leaf mould or peat.
Perennial Lobelia plants like a deep, rich damp soil, perhaps this could be provided by a pool that occasionally overflows.Perennial lobelias enjoy the same moist soil conditions as primroses, so these - especially the red or pinkish coloured varieties - make happy companion plants.
They are easily propagated to build up impressive colonies by dividing the clumps in early spring, as the new growth is awakening, either using a knife or a pair of digging forks.
Slugs find the young growths of these plants delicious, and should be deterred.
