Edging lobelia in light blue (Lobelia erinus) is a delightful annual that adds an airy feel and a soft splash of colour to beds and containers. Its tiny pale blue flowers form dense mounds around 10 to 20 cm tall, keeping their gentle charm all summer and well into autumn. With a compact habit and long flowering, it pairs beautifully with other ornamental plants and suits borders, edging, pots, window boxes and hanging baskets.
Sow the seeds very shallowly to about 0.1 cm. Do not cover them with soil. Simply press them lightly onto a slightly moist surface so they can access the light needed for germination.
Start sowing in March in trays or small boxes placed in a bright, warm spot. Seedlings need plenty of light and moderate watering to develop strong roots and a neat, compact shape.
Move young plants to their final position in May once the risk of frost has passed. Before planting out, harden them off for a few days by gradually getting them used to outdoor conditions.
Keep a spacing of 10 x 15 cm when planting. This gives each plant room to grow while still creating dense, eye catching patches of colour. Planting too closely can reduce flowering and weaken growth.
Edging lobelia flowers continuously from June to October. Its long season of bloom makes it a lovely feature in gardens and in containers, with delicate blue flowers to enjoy throughout the warmer months.
For best results, grow in fertile, free draining soil that stays lightly moist. The plant enjoys sun but also performs well in light shade. Water regularly during hot weather, as dry compost can reduce flowering. Feeding with a fertiliser for flowering plants helps keep growth strong, and trimming back after the first flush encourages fresh blooms and a tidy, compact mound.
