Lobelia x gerardii | Lobelia ‘Vedrariensis’
Lobelia plants are summer bedding classic perennials, typically suited for baskets and containers, as well as borders. Lobelia are easy to grow and flower reliably from the end of the spring frosts right through to the start of the autumn frosts.
Lobelia ‘Vedrariensis’ is a cross between Lobelia fulgens, Lobelia siphilitica, and Lobelia cardinalis, and is commonly called Purple Lobelia and Purple Cardinal Flower. It’s considered to be one of the most popular and loved flowers for summertime growth. It’s an upright, 3-4′ tall, vigorous perennial that beautifully boasts blindingly bright iridescent purple flowers spikes along with dark green leaves. As mid-summer and early fall come near, the dark green leaves turn purple. Along with being extremely bright and beautiful, this plant can be quite architectural as it adds vertical value to a landscape.
Does well in average, medium or wet soils under full sun or in partial shade. However, it would prefer some afternoon shade and to be in moist soil. It adds splashes of color to cottage gardens and garden beds.
