Lobelia jasionoides is ideal for areas where really low growing ground covers are needed and should be placed at the front of beds so that the tiny flowers may be easily seen and appreciated.

The easiest method of growing Lobelia jasionoides is from cuttings taken between July and August. Prepare the cuttings, including the final cut below a node, so that they can release their milky juice for about 5 minutes before dipping in a root hormone powder. Put the cuttings into a mix of 50% finely milled bark and 50% polystyrene, or 50% finely milled bark and 50% coarse river sand. Place in a covered mist unit, preferably with bottom heat. Cuttings should start rooting within three weeks and can then be repotted into a potting mix consisting of 50% compost and 50% coarse river sand. Feed with a kelp fertilizer every 3 weeks and pinch out tips to promote a bushy habit.

Seed is very fine and it is helpful to put a cloth under the plant to help catch seed, which may be collected from the end of February through March. Sow seed into a mixture of 50% finely milled bark and 50% sifted river sand. Top this mixture with a thin layer of fine sand so it is easier to see the seed when sowing. Cover with a very thin layer of finely sifted sand. Apply smoke treatment and water with very fine rose or mist every second day. Seeds should germinate in four weeks.
