Silver tree: Physical description

Leucadendron Argenteum is a tall, attractive tree that stands erect at a height of 7 to 10 metres. It has a sturdy trunk and thick, grey bark, with upright branches covered in large lance-shaped leaves that are up to 150 x 20 mm in size. The leaves overlap each other up the stem, covering the thick branches. The leaves have a silver-grey colour and are covered on both surfaces with thousands of tiny, soft, silvery hairs, with long white hairs on the fringe. The silver sheen of the leaves is due to the presence of these hairs, and the intensity of the sheen varies with the weather. In hot, dry weather, the hairs lie flat, making the leaves appear more silver, while in wet weather, they stand more erect to allow for better air circulation.

Silver tree is dioecious, meaning that the male and female flowers are borne on separate plants. The flowers are in dense heads at the branch tips, surrounded by leaves known as involucral leaves. The involucral leaves do not change colour while the tree is in flower, but they open wider, catching the light at a different angle and shining brighter silver than the rest of the leaves. The male trees are more showy, with more prolific flowering and brighter involucral bracts. The male flower heads are bright yellow balls that appear to glow inside the silver leaves. Both the male and female flower heads have a faint, pleasant scent.

Silver tree: How to grow?

Leucadendron Argenteum or silver tree is a popular ornamental plant known for its attractive silver foliage and bright red or yellow flowers. To propagate a silver tree, you can take stem cuttings from an existing plant and root them in soil or water.

Here is a general guide to follow:

Choose a stem cutting from a healthy, mature silver tree. It should be about 6 inches long and have at least two leaf nodes (the small bumps on the stem where leaves grow).

Discard any leaves from the bottom half of the stem cutting.

Dip the bottom end of the stem, cutting in the rooting hormone, which can help promote root growth.

Put the stem cutting in a pot filled with a well-draining soil mix, or place it in a jar of water.

Place the pot or jar in a warm, sunny location and keep the soil moist but not soggy.

After a few weeks, you should see new growth in stem cutting. When the cutting is well-rooted and has developed a good root system, you can transplant it into a larger pot or the ground.

It’s important to remember that not all silver trees will root successfully, so it may take a few tries before you are successful. Also, use a clean, sharp knife or scissors to take your stem cuttings to avoid introducing diseases to the plant.

Silver tree: Care tips

Leucadendron Argenteum, silver tree or silver bush, is a native South African plant known for its attractive, silver-grey foliage. It is a popular plant for landscaping, as it is drought-tolerant and can thrive in various soil conditions.

Here are some care tips for silver tree:

Plant it in a location that gets full sun or partial shade. It can tolerate some shade but will grow best in full sun.

Water the plant regularly, but avoid overwatering as it can be susceptible to root rot. Water the plant thoroughly. Allow the soil to dry out partially in between waterings to avoid root rot.

Use well-draining soil to prevent the roots from sitting in water. A cactus and succulent soil mix work well, or you can add perlite or sand to regular potting soil to improve drainage.

Fertilise the silver tree with a balanced fertiliser once a month during the growing season. It will help the plant to grow healthy and strong.

Prune the shrub regularly to keep it neat and encourage new growth. You can trim off dead or damaged branches and shape the plant to your desired form.
