Leuchtenbergia Cactus


Commemorating Eugene de Beauharnais, Duke of Leuchtenberg, 1781-1824, a French soldier and statesman (Cactaceae). A peculiar cactus from Central and North Mexico with stout, parsnip-like roots. It appears to have many leaves coming from a central stem; these are not leaves, however, but well-developed tubercles. On top of each is the areole with a cluster of long papery spines. One species only is cultivated L.principis, the flowers of which come from the top of the central tubercles. They are funnel-shaped, yellow and reddish-brown.


A compost with few added nutrients with 1/4 part added of sand, grit and broken brick is suitable. A little extra ground chalk can be added, about 1 ounce per bushel. Repot in March every 3 years, or before if pot bound, using deep pots. Place in full sun in the greenhouse, and do not water often, only when the soil is dry, between April and September, and keep quite dry in winter. The winter minimum temperature should be 40°F (4°C), in summer ordinary greenhouse temperature, provided there is plenty of ventilation.

Leuchtenbergia Cactus Propagate by seed sown in a regular seed compost in pans in March. Keep them at 70 °F (21°C), moist and shaded until the seedlings appear. Plants may also be propagated by rooting tubercles in sand.
