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.
