Electric blue lobelias pack dense color into tight, mounding plants—ideal when you need bright punctuation in beds, borders, or window boxes before the heat settles in. The Techno series stays compact and flowers heavily without constant fussing.

Plant in February through May while nights are still cool, and you'll get weeks of solid bloom. Once summer heat arrives, performance drops, so treat it as a cool-season annual here and plan your next move by June.
