Lobelia is a genus of flowering plants comprising more than 400 species mostly from tropical to warm temperate regions of the world. The genus comprises large and small annual, perennial and shrubby species, hardy and tender, from a variety of habitats, in a range of colours, but all have simple, alternate leaves and two-lipped tubular flowers, each with five lobes of intense colours. Several species are cultivated as ornamental plants in gardens, including Lobelia cardinalis - the cardinal flower or Indian pink - Lobelia siphilitica - the blue lobelia -and Lobelia erinus, and a number of hybrids have been produced, notably Lobelia × speciosa, a hybrid derived from L. fulgens, L. cardinalis & L. siphilitica, suitable for summer bedding schemes or growing in containers.

Sow my lobelia

Prepare the soil by breaking up the clods on the top of the soil, and push the coarser elements over to the edges with a rake. The smaller the seeds, the more you need to get a finer result. Sow seeds of less than 2mm in line or on the fly. For seeds between 2 and 4 mm, sow them in line with a few centimeters space in between. Finally, sow the large seeds in a heap: dig a little hole and put 2 to 5 seeds in it. Cover the seeds 2-3 times their height, add some sand if your soil is very heavy.

Water my lobelia

Water regularly in the first weeks. Try to avoid watering on sunny afternoons to minimize the amount of moisture lost to evaporation. If your plant is in a pot, check the top soil in the pot either by looking at it or touching it with your finger. In any case, if it hasn’t rained in a month, water !

Repot my lobelia

When your plants are carrying 4 real leaves, repot them in individual buckets to have them await the transplanting to the final location on sunny days.

Dibble my lobelia

Plant in open soil when temperatures exceed 5 ° C for a long time. It usually takes until mid-May. Prepare a cool, deep, rich, bright location in full sun or semi shade.

Fertilize my lobelia

Add some compost or compost juice every month.

Remove my lobelia

At the end of the season, you can tear off this annual plant without any qualms: it will not grow again next year.
