Riviera Sky Blue Lobelia

Riviera Sky Blue is a compact, mounded Lobelia erinus selection with blue flowers. PanAmerican Seed lists it for early spring and spring, with a 5-inch height and 8-inch width in partial sun. ## Plant Profile The official [Riviera Sky Blue plant page](https://www.panamseed.com/Products/039301263000724/lobelia-riviera-sky-blue/) gives an 8–10-inch spacing recommendation and identifies the plant as a compact lobelia. Its small footprint suits the front of a seasonal bed or a container where its blue flowers can be viewed up close. ## Growing Conditions The species profile from [NC State Extension](https://plants.ces.ncsu.edu/plants/lobelia-erinus/) recommends organically rich, moist, well-drained soil and regular watering. It describes Lobelia erinus as suitable for full sun to part shade; the cultivar listing specifies partial sun. In warmer climates, afternoon shade can help protect the planting from strong heat. ## Maintenance Keep the root zone evenly moist and water consistently, especially during dry weather. Avoid letting the soil dry out completely. Follow the spacing on the plant label and remove spent flower stems as needed to keep the planting tidy.
