Cissus rotundifolia

Natural range of Cissus rotundifolia

Cissus rotundifolia occurs naturally from Eritrea to southern Africa, the Mascarenes and the Arabian Peninsula. It is a climbing shrub or tree of the seasonally dry tropical biome.

Wild plants use tendrils to move through surrounding shrubs and small trees. As the vine extends, older stem sections become increasingly woody while the thick, slightly fleshy leaves remain spaced along the climbing shoots.

Care for Cissus rotundifolia

• Light: Keep it in bright indirect or strongly filtered light. Deep shade leads to long bare gaps and thinner new leaves.
• Dry-down: Let the mix dry partly between waterings, then water thoroughly and drain the pot. The thick foliage tolerates some dry-down, but repeated severe drought can still cause leaf drop and root stress.
• Substrate and airflow: Use a free-draining, aerated mix and avoid cool, wet conditions around the root zone. Low to average household humidity is usually sufficient when air can move around the vine after watering.
• Support: Guide young stems onto a trellis before they become woody. Use loose ties and do not force a mature stem through a sharp bend.
• Nutrition and root space: Use a light feed while stems and roots are actively growing. Repot when roots crowd the drainage holes, the vine becomes unstable or ageing substrate begins holding water for too long.

Troubleshooting Cissus rotundifolia

• Thick leaves wrinkle: If the mix is dry and stems remain firm, water thoroughly and drain. If the mix is still damp, check the stem base and roots; remove soft or dark tissue and restart in fresh free-draining mix when damage is present, or let firm healthy roots aerate before the next watering.
• New leaves become thin and widely spaced: Insufficient light can produce weak, open growth. Shift the vine step by step to a brighter filtered position and watch the next section of new growth for fuller leaves and shorter gaps. Older stretched sections will keep their current spacing. If the vine looks too sparse, cut a long stem back just above a healthy node to encourage branching.
• Lower leaves drop after a long dry spell: The thick foliage tolerates a dry interval, but repeated severe drought can trigger leaf loss. Rehydrate the root ball evenly and shorten the next dry-down until new growth remains stable.
• The stem base turns dark and soft in damp mix: Rot is active. Remove the plant from wet substrate, cut back to firm tissue and propagate sound nodes if necessary before restarting in fresh free-draining mix; follow our root rot guide for the recovery checks.

Cissus rotundifolia is toxic to cats and dogs

• Keep this plant away from cats and dogs that may chew it.
• Chewing may cause mouth irritation, vomiting, stomach pain or weakness.
• Contact a veterinarian after pet ingestion. Seek medical advice if a person swallows the plant and becomes unwell.

Why is it called Cissus rotundifolia?

Cissus comes from Greek kissos, ivy, a reference to the climbing habit shared by many species in the genus. Rotundifolia combines Latin rotundus, rounded, with folium, leaf.

Carl Linnaeus established the genus Cissus in 1753 in Species Plantarum, page 117.

Jean-Baptiste Lamarck first described Cissus rotundifolia in 1792 in Tableau Encyclopédique, volume 1, page 331.
