This is an unusual variety, with red blooms, which is very uncharacteristic of this genus and a rarity in collections. This selected cultivars bears beautiful flowers shaded in dark pinkish-red, orange-red, purple or wine-red with usually even darker flower edges. However a very few red flowered specimens will appear time by time among normal yellow flowered plants, and are very rare. They are sought after collector and are sold (when available) for very high ciphers for that reason. Their traditional source, of course, is Japan but they are also found in European collections too. And also - like for the normal Astrophytum - their flower colour tends to increase a darker tone ageing.
