Contrast these bluish grey-green patches with the robust burgundy of the Bushveld Kalanchoe (Kalanchoe sexangularis) and you have a striking mix of red and blue. These guys are not thirsty so let the soil dry completely before watering. They are hardy and will forgive even the most absent-minded gardener. Their name derives from the Chinese Kalan Chauhuy meaning ‘that which falls and grows’, so yes, they will survive! These water-wise companions take low maintenance to the next level.
