ENGLISH: Variegated Blue Rose, Variegated Blue Rose Agave, Variegated Silver Star
Description: Agave potatorumSN|540]]SN|540]] is a dwarf growing species that has very variable features. Some are medium sized plant that grows eventually up to 40 cm tall and 40 cm in diameter while others (called Butterfly Agave) are small-sized (20 -30 cm) and highly prized in Japan.
The cultivar Shoji-Raijin (sometime called the 'Silver Star' or 'Blue rose') is a magnificent miniature rosette of plump leaves that stay very small and compact. It has been selected in Japan, and is a unique miniature that produces offsets and forms a small clump of 6-7 cm rosettes. Mature plants stays in 10 cm pots only.
Leaves: Wide, thick, striking dusty-blue with few short spines and terminate in a distinctive, slightly twisted, reddish spine. The leaf margins display pronounced swellings at the base of the teeth. Usually the leaves do not shows noticeable leaf imprinting.
Variegated forms: Two variegated forms are known in cultivation, "marginata" whit a creamy or pale-green irregular stripe on the edge of the leaf and "mediopicta" with a broad white band down the centre of each leaf.
Subspecies, varieties, forms and cultivars of plants belonging to the Agave potatorum group
Agave potatorum Zucc.: Small Agave, growing solitary or slowly clumping, that forms an compact to open symmetrical succulent rosette. It is a very polymorphic species with a large range of variability and the size.- Agave potatorum f. compacta hort.: Dwarf cultivated form that grows eventually up to 20(-30) cm tall and in diameter. The leaves have distinct showy bud-imprints.
- Agave potatorum Tlaxiaco, Oaxaca, Mexico: This population has very nice bright orange marginal teeth.
- Agave potatorum var. verschaffeltii A.Berger in A.Berger: The old name ''verschaffeltii '' is still in use to distinguish plants with sinuous leaf margins and with teeth atop of outward-projecting bumps.
- Agave potatorum cv. Cubic: The leaves grow as if 2 leaves are fused together resulting in some of them having a 4 angled appearance and forming a square shape. Marginal spines can grow on up to all four of the leaf sides.
- Agave potatorum cv. Kichijokan: Variegated form with amazing symmetrical lotus like leaf pattern. The leaves have lateral, creamy-coloured variegations. Nice imprints are present on the back side of the leaves. The edges have large rusty coloured teeth and are a purplish/maroonish colour.
- Agave potatorum cv. Shoji-Raijin hort.: Also called 'Blue rose' it is tiny rosette of plump blue leaves that stay very small and compact. It produces offsets and forms a small clump of 6-7 cm rosettes. Mature plants stays in 10 cm pots only.
- Agave potatorum cv. Shoji-Raijin variegata marginata hort.: Has a creamy-white or pale-green irregular stripe on the edge of the leaf.
- Agave potatorum cv. Shoji-Raijin variegata mediopicta hort.: Has a broad white band down the centre of each leaf.
Cultivation and Propagation: Cultural requirements are similar to those of other Agave potatorumSN|540]]SN|540]]. They grow very symmetrically and stay in small containers, they need well-drained mixes and filtered sun or light shade exposures. Water regularly during the growing season allowing to dry between waterings; but be careful as heavy watering may result in some leaf cracking.
They are not as cold-hardy as many of the more northerly-occurring species. They're sensitive to frost and may be damaged if not protected.
Propagation: Exclusively by suckers (if available)
