Encephalartos longifolius (Suurberg Cycad,Thunberg’s Cycad) - 10 Seeds (2026 Harvest)

Encephalartos longifolius, commonly known as the Suurberg Cycad or Thunberg’s Cycad, is an impressive cycad native to the Eastern Cape of South Africa. This highly ornamental species is valued by collectors and specialty growers for its substantial trunk, long arching leaves, and bold architectural form.

The species is naturally variable in appearance. Its foliage ranges from green and dark green to distinctly blue-green or glaucous forms, depending on the individual plant and provenance. Mature plants develop a dense crown of long, gracefully arching leaves that can reach approximately 1–2 meters in length.

Encephalartos longifolius is a long-lived specimen cycad and an excellent choice for specialty nursery production, botanical collections, cycad collections, and landscape specimens in suitable climates.

Germination & Cultivation

Encephalartos seeds contain embryos that continue developing after the seed has matured, and germination should not necessarily be expected immediately. Seeds are best grown in warm conditions in a well-draining propagation medium with careful moisture management.

Germination can occur gradually over an extended period. The growing medium should remain lightly moist but never continuously saturated, as good drainage and aeration are particularly important during germination and early seedling development.

Once established, Encephalartos longifolius develops into a substantial and highly ornamental specimen. Its impressive size, long arching foliage, variable green to blue-green coloration, and classic cycad form make the Suurberg Cycad especially desirable for professional growers, specialty cycad collections, and botanical collections.
