Nursery contributed plant descriptions

EXCLUSIVE! Is it true blue you love? Well, an abundance of truly azure blue flowers is what you'll get when you grow this rare South African perennial. Typically Lobelia-shaped flowers of soft royal blue are arranged in crowded radiating clusters atop the many base-branching stems to 16” tall. Handsome, shiny, bright green foliage. Cut back after bloom and you may get more. Grow this lovely rarity in light well-drained soil, rock gardens or containers with some compost added. Breathtaking when massed, it combines stunningly with Ursinia anthemoides ‘Solar Fire' or Cotula lineariloba ‘Big Yellow Moon'.
