About Climbing asparagus fern
Semele androgyna, known as Sémélé androgyne, is an evergreen climbing shrub native to the Canary Islands and Madeira, featuring flattened green stems (cladodes) that resemble leaves and bear its small, greenish flowers. Its peculiar form and climbing habit make it ideal for covering walls or pergolas in mild climates, adding an exotic and structural touch to the garden. It can also be grown in large pots for patios or terraces, where its trailing stems can create a cascading effect.

Canary Islands and Madeira
Care tips
It prefers partial shade or filtered light, avoiding intense direct sun which can scorch its cladodes. It requires moderate watering, allowing the top layer of the substrate to dry out slightly between waterings; it tolerates short periods of drought but appreciates ambient humidity. A well-drained, slightly acidic substrate is ideal, with a mix of garden soil, peat, and sand. A common mistake is overwatering, which can lead to root rot, especially in winter.
