Encephalartos arenarius 'True Blue Form'

Encephalartos arenarius ‘True Blue Form’ is a nursery selection of the dune cycad, a multi-stemmed species native to sandy coastal habitats in South Africa’s Eastern Cape. Growers use the True Blue label for plants selected for strongly blue foliage, while the species also includes green-leaved plants. ## Foliage and Setting The [nursery listing](https://fairviewnursery.com/plants/cycads/) sells this form separately from Standard Form. A grower’s [True Blue description](https://caudexfarm.com/product/encephalartos-arenarius-true-blue/) identifies the selection by its intense blue leaf color; the [SANBI species account](https://pza.sanbi.org/encephalartos-arenarius) confirms that a blue-leaved form occurs within E. arenarius. The blue label describes a horticultural selection, not a separate botanical species. ## Growing Conditions E. arenarius comes from sandy coastal dune forest and scrub. Provide a sheltered position with freely draining soil; partial shade to moderate sun suits the species, with gradual exposure changes for container-grown plants. Keep moisture available during active growth, but let excess water drain and protect the cycad from frost. ## Maintenance Inspect the crown and cones for scale or mealybugs, and use gloves when handling seeds. Keep the plant’s exact form label with it when propagating or sharing it, since foliage color is the distinguishing trait described for this selection. The [SANBI assessment](https://www.sanbi.org/wp-content/uploads/2026/03/Encephalartos-arenarius-NDF-supporting-document.pdf) covers its natural habitat, and the [cultivation reference](https://www.llifle.com/Encyclopedia/PALMS_AND_CYCADS/Family/Zamiaceae/29902/Encephalartos_arenarius) gives species-level garden guidance.
