Cerinthe (AKA Honeywort) is an elegant looking plant that stands out for its unusual habit. Each stem arches upward out forward with a seemingly endless series of purple-blue bell shaped flowers. This plant works very well in larger containers or flower borders.
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.
Do not transplant outside until daytime 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.
Space or transplant 30-45cm (12-18″) apart. Water regularly during dry spells. Mulch around the stems in spring to keep the soil cool and moist. Cerinthe tends to self-sow, but is never invasive.
