Cultivation and Mail Sale
of Cacti and Succulents.


Rebutia simoneana R736
 Green body, whitish spines, deep orange flowers

 

Description: Small clumping plants,
Stems:  Individual heads,
short, cylindrical, 3-6 cm wide, 4 cm tall.  The colour of the epidermis varies from grey-green to olive-green.
Spines: Short whitish radials with few pale brownish centrals.
Flowers:
 4-4,5 cm in diameter, bright orange-red.
Roots: Fibrose root, eventually slightly enlarged and juicy .
 

Cultivation: These small growing plants come from mountainous areas, so like bright light, and cool and dry conditions in the winter.  This is important for the flowers as well as for the plants'  health. Without this cool winter period (0-10 C) they normally won't get many buds. They have a thick taproot, and are of difficult cultivation and rot prone, because of a great sensitivity to excess of watering, not easy to get to any large size on their own roots (it's really a challenge to grow them into a large clump). They are commonly grafted to avoid root problems, and in order to make them easier to grow.  Suited for brightly exposure; but they can tolerate sunny exposure.
Suited for airy exposures.  It is a small container size plant and prefers a deep pot and good drainage to accommodate its tap root.. It will occupy a small pot comfortably, and eventually remain a manageable sized house plant.
It is very cold resistant  as low as to -10 C or less for short periods of time.  It is a fine plant for a rock garden or container, contrasts well with agaves, yuccas, and low-growing flowering plants. This variety is also likely to flower as a house plant, but results will depend on a variety of growing conditions.
Pests & diseases:   It is especially prone to root rot, therefore, underpot in a smaller container filled with very porous compost.
Propagation: By cuttings, as it branches freely from the base.  It can also be grown from seeds or by graft.  Seeds can be sown in the spring or summer.  The seedlings should not be disturbed until they are well rooted, after which they can be planted separately in small pots.
