A. asterias cv. OOIBO RURI KABUTO (forma nuda)
 

A. asterias cv. OOIBO KABUTO  is a Japanese selected strain with big areoles.
The "OOIBO" is very similar to the common A. asterias, but it has very large characteristic and woolly areoles, the colour of the wool also varies from pure white, to pastel, yellowish, orangish or brownish depending on the clone. So it is easily distinguishable from the standard  A. asterias that has relatively small scarcely woolly greys-white areoles. However the large areoles "trait" can be appear in combination with  other A. asteris cultivars, for example it can be found in A. asterias nudum: this combination may be named A. asterias cv. OOIBO RURI (nudum) KABUTO)

Family: Cactaceae (Cactus Family)

Scientific name: Astrophytum asterias (Zucc.) Lem  

cv. OOIBO KABUTO also known as RURI KABUTO (Naked body)

Origin Garden origin (Nursery produced cultivar)

Conservation status: Listed in CITES appendix 1.

 

This is one of the most famous and peculiar Japanese Astrophytum cultivars.

Cultivation remarks: It is not too difficult in a greenhouse, although it grows quite slowly.  The plants need  a loose well-drained mineral soil.  They need a good amount of light.  Watering can be done weekly during the summertime, if the weather is sunny enough, with a little fertilizer added.  Kept this way, plants will show a healthy, although slow growth.  They are frost hardy to -4 (-10) C

Propagation: By seeds, remembering that  seedlings dislike strong light and dry conditions, and need to be repotted frequently.  But plants are often grafted to accelerate growth, as they would generally take at least  five years to reach maturity on their own.  However the grafted plants are typically rather tall-growing, in comparison with plants on their own roots, that are usually flatter to the ground.
