They are perennial plants that reach 1 meter in height. They have long and narrow leaves. The showy flowers are tubular in shape and orange-red in color. They bloom from mid spring to late fall.

They are used to create groups combined with other plants such as Teucrium, Echium, Bupleurum, Agapanthus, Cineraria, Helychrysum, etc. They are suitable for gardens by the sea.

Lobelia laxiflora can grow in direct sun, semi-shade and shade exposures. They resist frosts down to -10 ºC but lose their leaves and sprout again in spring.

The soil must be well drained, contain organic matter and a little lime. Planting is done in spring

They are drought resistant plants. Water every 10 days in summer and much less the rest of the year.

Fertilize in autumn with manure and in spring with mineral fertilizer every 20 days.

They do not need pruning; their expansion must be watched because they tend to become invasive.

They are quite resistant plants to pests and diseases but are sensitive to excess humidity.

They propagate by division in early spring.
