Lobelia speciosa Crimson Princess Gencrim


Beautiful flowers and evergreen foliage

Glowing crimson red blooms are crowded onto the upright stems of this beautiful plant in summer and autumn. Burgundy red leaves are a feature from spring onwards when they emerge from the soil.


Happiest in a part shaded border - ideal at the edge of a pond or in a bog garden.


Best in a moist or wet soil. Enrich the soil before planting by adding organic matter - home made garden compost or well rotted manure is fine. Water frequently in dry weather through the growing season and protect the plant from damage by slugs and snails. Cut back old stems in late spring when new leaves are spotted at the base of the plant.

Planting instructions

Water the plant in its pot thoroughly before planting – give it a good soaking. Prepare the area by digging a hole twice the size of the pot. Dig compost into the base of the hole. Remove the pot and position the plant in the hole, with the top of the rootball about level with the surrounding soil. Refill the planting hole with a mixture of garden soil and compost, firming as you go. Water in well and keep well watered during the plant's first year.
