Product Details

Lobelia erinus. Vivid navy blue flowers adorn this tiny, trailing Lobelia, making it ideal for stuffing between other plants as a ground cover. The flowers are highly attractive to bees and butterflies. Grow Regatta Midnight Blue Lobelia seeds in window boxes or hanging baskets, and allow it to cascade over the edges of any container. In moist soil it will thrive in full sun or partial shade. This trailing Lobelia looks fabulous with Alyssum, and fills in empty corners really well. Sow the tiny, dust-like seeds on the surface of moist soil, and do not transplant outside until night time temperatures are well above 10°C (50°F). Regatta Midnight Blue is a recipient of the prestigious Royal Horticultural Society Award of Garden Merit.

All About Midnight Blue

When I Get My Seedling Home

When I Get My Seedling Home
Keep seedlings under very bright light to prevent legginess. Artificial lights are ideal, but a bright (ideally, south-facing) room will work for the short term. You may have to pot on seedlings more than once before they go out to allow for root growth. This is done by transplanting them into a slightly larger container with enough additional soil to keep the container mostly full. Keep the soil moist by daily watering and allow for free drainage so the plants are never sitting water.

Transplanting

Transplanting
Do not transplant outside until night time temperatures are steadily 10°C (50°F) or warmer. This may mean keeping seedlings indoors for up to a month. The plants should not require any fertilizer until transplant time.

 

Growing

Growing
Lobelia is not cold hardy. Be strict about the transplanting temperature above. Lobelia is a spreading, cascading annual, so it's excellent for hanging baskets, window boxes, and tucking in between other annuals to fill in space. If growing in a row, start by spacing 15cm (6") apart. They will quickly grow into the space by early summer.

How to Grow Lobelia

Step 1

Timing

Sow indoors 6-8 weeks before planting out, and do not plant out until nighttime temperatures are reliably 10°C (50°F) or warmer. On the coast this means sowing indoors around in early April, and planting out in late May. Starting indoors is highly recommended.

Step 2

Starting

Sow on the surface of sterilized seed starting mix. Do not cover the dust-like seeds. Do what you can to sow them evenly on the soil. Provide bright light and a soil temperature of 18-25°C (65-75°F). Germination takes 15-21 days. Water with a mist sprayer. Consider starting Lobelia in 12- or 24-cell plug inserts. It is nice to be able to pull apart clumps of Lobelia for later transplanting. Smaller cell inserts work alright too, but the seedlings tend to grow together in mats, so pulling them apart will cause some loss.
