A Bolivian beauty with a spherical grey/green, ribbed body, slightly depressed at the top and reaches up to 8cm in height with a spread of up to 12cm. Beware the thorns hidden in the the wool around the areoles. Night time flowering with narrow, funnel shaped blooms on 20cm long stems. Said to be cold hardy down to -7c if kept perfectly dry. We have not tried this one outside yet in our southern, coastal garden but will let you know the results after trials during 2023/2024 winter.
