Hedera canariensis is commonly planted as an ornamental, engulfing fences, house walls, sheds, and old tree trunks. But beware, although it has an alluring look, It’s a vigorous grower and will need to actively be kept at bay to prevent it from taking over! Although it prefers moist, rich soil, it will tolerate poorer conditions.
I. Appearance and Characteristics
Hedera canariensis, the Canary Island ivy, Canary ivy or Madeira ivy, is a species of ivy, native to the Canary Islands and possibly the Atlantic coast of northern Africa.
It is an evergreen perennial climbing or trailing woody plant shrub or bush, growing to 20–30 m high where suitable surfaces (trees, cliffs, walls) are available, and also growing as ground cover where there are no vertical surfaces. It climbs by means of aerial rootlets which cling to the substrate. In warm climates, it grows more rapidly and becomes established faster than the related H. hibernica, and H. helix. It is endemic to the Canary Islands where it is quite common, especially in the Laurel forest of Barbusano.
The leaves of Hedera canariensis are broad, 5 to 20 cm, glossy dark green in color and a little leathery, with 1-5 lobes, regular in size and shape. It is cultivated in gardens and used in floral arrangements. The flowers are greenish and the fruits, globular and black when ripe. Young stems are green or greenish-brown, sometimes tinged with red or purple, becoming gray or gray brown at maturity.
They are climbing plants with evergreen leaves that may grow from the bottom of the ravines and river canyons lining the entire surface of the wall or cliff. Ivy climbs with adventitious roots and can reach up to 50 meter in length. Ivies are plants adapted to the laurel forest, a type of cloud forest habitat. European Ivy for example, is believed was spread by birds that helped to colonize large areas again where it had disappeared during the glaciations.
II. How to Grow and Care
Sunlight
Light plays a crucial role in maintaining healthy growth and the shape of algerian ivy. It grows well in bright light, and thus it is advised to provide it with indirect light for 6-8 hours every day. Avoid direct exposure to strong light as it can burn the leaves, especially in summer.
Use artificial light as a supplement in winter. Although it can grow in weak light, long-term lack of light may cause faded leaves and slender stems. This will affect its ornamental value and make it vulnerable to pests.
Temperature
Algerian ivy natives in Eurasia and North Africa. It prefers relatively cool temperatures. It grows at temperatures in range of 10 to 27 ℃, preferably at around 18 ℃. While algerian ivy grows well in humid air, it can also withstand the environment with relatively low humidity. Spray should be prepared to moisten it in dry seasons.
Watering
When the soil is dry, add water until excess water drains from the pot. Avoid accumulated water at the base of the pot to avoid root rot and other diseases.
Soil
Algerian ivy grows best in well-drained fertile soil, whether neutral and slightly acidic. The preferred pH ranges from 6.0-7.5. The plant tolerates poor soil and can survive in any loose, ventilated culture media. Mix garden soil or peat soil with leaf mold at 1:1 ratio to ensure long-term healthy growth and brightness of leaves. Replace the pot and half the soil once every year or two.
Fertilizing
Generally, algerian ivy should be fertilized once a month in spring, summer, and fall. Since nitrogen is necessary for leaves to grow, apply water-soluble nitrogen fertilizer suitable for foliage plants. Mix the fertilizer according to instructions and pour it on the soil near the roots. For variegated varieties, use nitrogen, phosphorus, and potassium fertilizers at a ratio of 1:1:1 to maintain the color of leaves. Don’t let the fertilizer touch the leaves, as it can burn them. It is unnecessary to fertilize in winter or extremely hot summers, which is the dormant period.
Planting Instructions
Propagate algerian ivy by cuttings in the spring and fall. The container should not be too large, or water may accumulate in the pot. Generally, you can cultivate 3-5 plants in one pot. When the plant is too large, replace it or prune the plant. Provide support for it to climb.
Pruning
Pinch young shoots from time to time to help branches grow and shape your plant. Cut off withered, yellow, or infected leaves of adult plants with clean scissors frequently. If the vines are too long, they can also be cut short once in spring every year. Algerian ivy is adapted to climbing scaffolds to get various shapes by pruning and pulling.
Propagation
As aerial roots grow well in moist air, algerian ivy mainly reproduces through cuttings at any time except extreme weather like cold winter and hot summer. Use clean scissors to cut the lower part of the stem to 10 to 13 cm long. Remove the leaves 5 cm below the bottom and put it in water. Maintain a cool environment with relatively high air humidity. When the newly-generated root is 5 to 8 cm long, move into a pot.
Transplanting
The best period to transplant algerian ivy is during the S1-S3, often called the cool seasons. That’s when the plant can focus on root establishment before the heat of summer. Choose a location with at least partial shade, as algerian ivy thrives in such conditions. A friendly tip: Keep soil conditions moist, not wet, to promote healthy transplant growth.

- Spider mites: These tiny pests can cause yellowing and webbing on the leaves. Increase humidity around your ivy by misting the foliage regularly to deter spider mites.
