Star Cactus Astrophytum asterias TRY 7,500 Astrophytum asterias 'Star Shape' Star Cactus TRY 1,500

Star Cactus is a high-value Astrophytum with a flat round body and a star-like top view. The storefront name stays simple; “Star Shape” is handled in technical and dictionary fields.

This is a single specimen. Symmetry, body fullness and areole pattern matter for the buying decision. The spineless body can be sensitive, so avoid unnecessary handling and constant repositioning.

After delivery, do not rush watering. Keep the plant in bright but non-scorching light for the first week, then water only when the mix has dried fully. A dry rhythm is safer for this kind of flat-bodied Astrophytum.
