Flaming Katy

The Kalanchoe blossfeldiana, sold as Flaming Katy, is a compact Madagascan succulent with thick scalloped leaves and dense heads of small four-petalled flowers in scarlet, pink, orange, yellow and white. The flowers last for weeks, which is unusual in a plant this size.
It is used as a low massed bedding succulent in warm climates and as a seasonal interior plant everywhere else, and it asks for almost nothing beyond sharp drainage.
Flaming Katy delivers a long block of flower colour at ground level on almost no water.
