Echinofossulocactus densispinus
(Syn: Stenocactus ochoteraneus)
|
Flowers in March-April |
Description: Solitary
or clustering cactus.
Stems: up to 8 cm tall, 10 cm in diameter with woolly apex;
Areoles: young areoles with white hair.
Ribs: Barely visible beneath the numerous white radial spines,
thin sometimes wavy.
Radial spines: Radials white numerous 22 or more.
Central spines: 4, the superior one up to 6.5 cm long flattened
dark-brown that age to tan.
Flowers: Pale pink or pale greenish yellow, 2.5 cm long.
Fruit: Greenish fruit withwhitish scales.
Culture: Easy to to
care and flower. No absolute schedule can be given
for watering as various factors (Soil mixture, containers,
drainage, temperature, size of plant) influence water use, so - as
a general rule - the soil should be thoroughly wetted at each watering
during the active growing season (spring and summer), water when the top
1,5- 2 cm of soil feels dry to the finger. Do not soak the soil during
the dormant period. Be careful, excessive watering can make root and/or
stem to rots. Make sure there is good air circulation between plants.
Good drainage is essential along good moisture retention properties and
adequate nutrients availability. |
Require bright sunlight to grow
well. Dormant plants do best at temperatures from 5-10°C (but will
tolerate -5° for short periods). The cooler temperatures develop
sturdier plants and encourage the formation of flower buds.
Propagation: By offsets which often are found growing around the
base of the plant, Remove the basal offset (if available) in
spring or summer and let the cuttings dry for a few days before
inserting in compost or (usually) by seed. |
