What is the difference between Encephalartos altensteinii and E. natalensis?

Natalensis usually shows leaflets that reduce to prickles toward the leaf base and a slightly bluer new flush; altensteinii keeps broader leaflets further down the rachis and holds a deeper glossy green. Where they overlap, an expert assessment settles it.

How fast does Encephalartos altensteinii grow?

Fast for a cycad — expect a new flush most years in good conditions and visible trunk within a decade or two from seed, which is why it is the most practical large Encephalartos for a garden.

Eastern Cape cycad

Encephalartos altensteinii — the Eastern Cape cycad

Encephalartos altensteinii is the big, generous, green Eastern Cape cycad that turns a garden into a landscape. It grows fast by cycad standards, clumps freely into multi-headed groups, and the oldest cultivated specimen in the world — the plant at Kew, potted in 1775 — is this species.

About Encephalartos altensteinii

It occurs along the coastal belt from the Eastern Cape into southern KwaZulu-Natal, on forest margins and rocky slopes where rainfall is reliable. That upbringing shows in cultivation: it accepts more water and less brutal drainage than the arid-country blues, and it rewards feeding with long, arching, glossy leaves.

Buyers mostly compare stems. A single-stemmed plant of a metre is a fine garden subject; a mature multi-headed clump with three or four crowns is a different order of object and priced accordingly. Because the species suckers well, large clumps in cultivation are common enough that there is never a reason to look at wild-collected material.

How to identify it

Long, straight to gently arching leaves, often 2 m or more on mature plants.
Glossy mid- to deep-green leaflets, broad, with a few spines along each margin.
Robust trunk that clumps at the base, forming multi-headed groups with age.
Large green cones — females produce heavy cones with bright orange-red seed.

What drives the price

Trunk height and the number of established heads.
Clean, unscarred trunk with even leaf spacing.
Whether the plant has been root-established after transplant, or lifted recently.
Verified identification separating it from E. natalensis and E. lebomboensis.

Seedlings are affordable and widely available; the money is in trunked and multi-headed specimens, which are priced by trunk metre and head count. Compare the live listings below before settling on a figure.

Permits and paperwork

Listed as vulnerable and protected in law. A possession permit is required for private ownership and nurseries must hold a selling permit — both are verified on the listing before a sale closes here.

Growing it

One of the easiest Encephalartos to grow: sun to light shade, deep well-drained soil, generous summer water. It tolerates coastal wind and moderate frost once trunked, and it transplants better than most.
