Magnify glass

Lobelia speciosa Tania

Great for cut flowers

A star for a late summer border. The upright stems are covered in glossy green leaves which have a purple tinge and set off the unusual flowers of rich purple. These are crowded on the stems until well into the autumn. Excellent for flower arranging as well as in the garden.


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.
