of Cacti and Succulents.


Parodia masii
 

It is a very variable species, with dense, strong and curved spination, often yellow or amber-coloured.

Propagation: By Seeds. The seeds of this plant are extremely small, and must be sown on the surface of the germination substrate (not buried!!) But the seedlings after germination are so minuscule and delicate that it is quite problematic to keep them alive.  So for this species one usually uses the baggy germination technique (in a sterilized pot hermetically closed in a plastic bag.

Family: Cactaceae (Cactus Family)

Scientific name: Parodia maassii (masii or massii) ((Heese) A. Berger
Kakteen (Berger) 344, 1929

Origin: It is native to Southern Bolivia and Northern Argentina.

Conservation status: Listed in CITES appendix 2.

Synonyms:  

  • Echinocactus maasii Heese
  • Malacocarpus maassii
  • Bolivicactus maassii

 

Description: Solitary or clumping.  This species is very variable.
Stem: The plant presents an extended spherical stem, mid-green to intense green in color, 15 cm. wide, with the apical part densely covered with white wool.
Ribs: 13- 21, chinned and arranged in spiral.
Areoles: Big and woolly at first, but they become naked with age.
Spines: Curved, dense, and variably coloured.
Radial spines: 8-10 (or more).  Usually yellowish or amber at first and white later, 5-10 mm. long, opened on the outside and a little curved inwardly.
Central spines: 1-4 (or more), strong,  measuring between 3 and 7 cm.  They are yellow on the upper part of the plant and go upwards.   In older parts they become clear yellow, and go downwards.
Flowers:  Funnel-shaped, large coppery-yellow or orange, but they can also be carmine or red with an orange centre. 3 (or more) cm across.
Blooming season: Spring and summer, they usually appear one by one in succession.
 

 


Cultivation:
Water these plants moderately but regularly, and fertilize with a low nitrogen fertilizer every 6 to 8 weeks, from mid-spring to late summer.  This plant should remain dry at other times, except for a quick, periodic misting on warmer days in late winter.   Watering Needs: Regular water in summer.  Keep rather dry in winter.  It rots easily if the substrate is wet and cold, and tends to lose its roots in winter.   It can tolerate light frost (-1C°). This species grows better with partial shade.
If your climate is warm enough to grow this plant outside, be sure that soil is well drained and sun if full, but with protection from strong mid-day rays.
