Riviera Lilac Lobelia

Riviera Lilac is a compact, mounded annual lobelia in PanAmerican Seed’s Riviera series, with lilac-colored flowers and a low garden profile. The catalog lists the series at about 5 inches tall and 8 inches wide, for beds, borders, containers, and color bowls. ## Garden profile PanAmerican Seed’s 2016 catalog identifies Riviera Lilac among the named color selections in its Lobelia erinus Riviera series. The series entry gives a 5-inch height and 8-inch spread; these measurements describe the series and are kept as compact garden-planning dimensions. The catalog does not specify a USDA hardiness zone or a bloom season for this color selection. ## Placement Use the rounded mound near the front of a planting, in a container, or in a color bowl. Lobelia erinus is generally grown as an annual bedding plant, so local conditions and seasonal planting schedules determine when it performs best. ## Maintenance Keep containers and beds watered according to local weather and soil conditions, and remove spent growth if the mound becomes untidy.
