What Lobelia Blue Carpet is

Lobelia Blue Carpet (Lobelia erinus) is an annual flower of the bellflower family (Campanulaceae). Lobelia is a good choice for colourful decoration in the garden, along paths and edging, or around trees.

If grown at home, it is best in a window box on the balcony or in a hanging basket.

Lobelia blooms from May to the end of October with colourful small flowers in white, blue, violet, pink or pale yellow.

It falls into the category of dwarf plants, as it does not grow taller than 30cm.

Lobelia is a low-growing flower with a cloud of tiny blue, white or purple blooms — for edging, hanging baskets and window boxes.

How to sow and grow Lobelia Blue Carpet

• Spacing: 10–15 cm
• Germination: 10–20 days at 18–22 °C

Sow lobelia by mid-spring on the surface of good seed compost. When the seedlings are large enough to handle, prick them out and grow them on in cooler conditions until big enough to plant outdoors. When the lobelia plants are well grown and all risk of frost has passed, acclimatise them to outdoor conditions for 7 to 10 days. Transplant outdoors in sun or partial shade into moist, fertile, well-drained soil 10 cm apart. Lobelia should be watered moderately, taking care not to let the soil dry out. In summer it is watered more generously.

Sow in January–March in clusters. Do not let the substrate dry out.
