Regatta Rose Lobelia

Regatta Rose is an early-flowering trailing lobelia with a compact mound and stems that cascade over the edges of hanging baskets and larger containers. PanAmerican Seed lists it for early spring and spring, and reports that it can flower up to four weeks earlier than other trailing varieties. ## Plant profile The plant reaches about 6–8 inches tall and 10–12 inches wide. Allow 10–14 inches between plants for spacing. Its rose-toned flowers and trailing habit suit containers, color bowls, and small garden spaces. The official [PanAmerican Seed Regatta Rose profile](https://www.panamseed.com/Products/039301242004669/lobelia-regatta-rose/) identifies it as Lobelia erinus with a mounded, trailing form and partial-sun exposure. ## Growing conditions Grow it in partial sun and organically rich, moist, well-drained soil. Keep the root zone consistently moist, especially in containers; North Carolina Extension notes that Lobelia erinus does not tolerate drought and tends to perform best in cool spring weather. In cooler regions, this tender species is commonly grown as an annual. The [North Carolina Extension profile](https://plants.ces.ncsu.edu/plants/lobelia-erinus/) gives species-level guidance on moisture, light, and seasonal performance. ## Maintenance Water regularly without leaving the roots in waterlogged soil. If flowering and foliage decline in summer, trim the plant back after flowering to encourage fresh growth. Its cascading stems are most visible near the edge of a basket, planter, or color bowl.
