Astrophytum asterias cv. Hanazono is a distinctive and highly sought-after Japanese cultivar of the Astrophytum asterias species, commonly known as the Star Cactus. It's prized by collectors for its unique features, particularly its pronounced star-shaped form, additional woolly areoles (small patches of wool or hairs) along its ribs, and its tendency to bloom from multiple points rather than just the apex.
 

Here's a breakdown of its key characteristics and care:

Appearance

·        Shape: Flattened, disc-like, with distinct radial symmetry and pronounced, angular ribs that create a star-like shape.

·        Surface Texture: Smooth green body adorned with white flecks or woolly dots that can form intricate patterns. Some forms, like 'Super Hanazono', have an intensely white and furry appearance.

·        Size: Remains relatively compact and is a slow grower.

·        Flowers: Produces large, bright yellow flowers, sometimes with orange centers, that bloom during the warmer months and last for a day or two each. Unlike the typical Astrophytum, flower buds develop from the median line between two ribs rather than from the areoles.

Care requirements

·        Light: Prefers abundant, bright, and direct light but should be introduced to full sun gradually to avoid scorching. Some sources recommend filtered light or protection from harsh midday sun.

·        Watering: Water sparingly and allow the soil to dry out completely between waterings to prevent root rot. Water once a week or every 10 days in summer, and significantly reduce watering in winter during dormancy (when nights are below 50°F / 10°C), watering only when the soil is completely dry.

·        Soil: Requires a loose, well-draining soil mix that mimics its natural desert habitat. A good mix typically includes components like clay, loam, sand, perlite, pumice, or granite stone. Avoid heavy, water-retentive soils.

·        Temperature: Thrives in warm temperatures, ideally between 65-80°F (18-27°C) indoors. It's suited for USDA hardiness zones 9a–11b.

·        Fertilizer: Feed with a low-nitrogen, balanced cactus fertilizer during the growing season (spring and summer), about once a month, avoiding fertilization in fall and winter.

·        Propagation: Primarily propagated by seed. Grafting can accelerate growth but may result in taller plants compared to those on their own roots. 

Common problems

·        Overwatering: The most common issue, leading to root rot and splitting of the epidermis.

·        Inadequate Soil Drainage: Can contribute to overwatering issues.

·        Pests: Watch for mealybugs, scale insects, and spider mites. 

Interesting facts

·        The name "Hanazono" loosely translates to "field of flowers," referring to the cultivar's tendency to bloom from multiple points.

·        It's considered a rare and highly sought-after cultivar due to its unique features.

This unique cactus is a rewarding addition to a collection, but its specific needs, especially regarding watering, require careful attention.
