Riviera Blue Splash Lobelia

Riviera Blue Splash is a compact, mounded Lobelia erinus with light blue flowers splashed with white. PanAmerican Seed describes the Riviera series as extra early flowering, about 15 days before standard varieties, and lists Blue Splash for early spring and spring. The breeder gives a mature size of 5 inches high by 8 inches wide.

Their compact outline works along a path edge or as a low front layer in a mixed planter. PanAmerican lists the selection for partial sun. ## Growing conditions Lobelia erinus is generally grown as an annual and often blooms most reliably in cooler weather. Plant it in moist, well-drained soil and give it sun or partial shade. Illinois Extension notes that heat can interrupt flowering and recommends watering and shearing after the first bloom to encourage continued summer flowers.

Trim faded stems after the first flush, then water regularly while new growth develops.
