Hot air balloons in the garden? Absolutely! These light weight tropical climbers produce exotic blooms that generate a double take every time, usually followed by “What the . . .?” The wavy, upswept petals form a rounded dome, brightly colored in crayon-rich shades of red, yellow and reddish-pink. Plant as container annuals in colder parts of the country and in the ground perennials in the warmest regions – fun anywhere. Provide your gloriosa lilies with something to clamber up – a trellis, tea rose or open form shrub – and watch them put on a show.
