Euphorbia francoisii Leandri
Euphorbia francoisii var. francoisii
Euphorbia francoisii is a small caudiciform plant, up to 6 inches (15 cm) tall, that has the most variable leaves in the plant kingdom. No two plants have the same leaf shape or color, even if they are clones. The new leaves emerge as new shapes and colors, completely unpredictable. They are up to 3.2 inches (8 cm) long and up to 1.2 inches (3 cm) wide. Colors can range from dark-green, pink, purple, white, and variegated. Flowers are yellowish-green to pinkish and appear in the late sprint to early summer.
USDA hardiness zones 10a to 11b: from 30 °F (−1.1 °C) to 50 °F (+10 °C).
How to Grow and Care
Euphorbias are very easy to care for. These plants require a little pampering to become established, but once they are, they are self-sufficient. More die from too much care and watering than from neglect. Euphorbias need well-draining soil and lots of sunlight. They are not particular about soil pH, but they cannot tolerate wet soil. Unlike most succulents, Euphorbia does not handle long periods of drought well. It may need weekly watering during the summer. Water whenever the soil is dry several inches below the surface. Water deeply, but don't let them sit in wet soil, which can cause root rot. Add some organic matter or fertilizer to the planting hole. If you are growing them in containers or your soil is poor, feed with a half-strength fertilizer monthly.
These succulents can be grown from seed, but they can be difficult to germinate (or even find). They are usually propagated by cuttings. This can be tricky because of the exuding sap. Rooting hormone is recommended with Euphorbias. They tend to grow problem-free, but there are a few pests and diseases to be alert for.
