  Monvillea spegazzinii forma cristata (Type A)
(Syn: Cereus spegazzinii)
CACTUSPEDIA       

 


Monvillea spegazzinii "cristata" (Type A)
This easy to grow plant  is very attractive because of its spectacular blue-green marbled stems with pronounced sculpture effects. 
There is also a similar crested form (Type B)  with white purplish mottled  stems.
 

Description: The typical Monvillea spegazzinii is a fast-growing slender shrubby cactus that has  bluish stems that creep along the ground to form a shrub. There are two similar but slightly different crested forms (Type A and type B) that are now widely cultivated for their beautiful stem with pronounced sculpture effects.
Stems: Bluish-green up to 25 cm tall and wide.
Roots: Tuberose and succulent, Even adventitious roots of Monvillea spegazzinii become succulent.
Flowers: 10 to 13 cm in length with a slender tube, reddish outer perianth segments and white inner ones.They arise from near the top on the sides of the stems; buds point upward but curve suddenly downward when the flowers open. They bloom at night.
Remarks: These plants produce monstrous crests, and crests occasionally produce normal shoots.

Cultivation: Produces best results in loose and very drained soil, rich in leafmold, and if sufficient water is supplied in warm weather a rather considerable growth can be made. It needs semi-shade. The plants will stand but little cold and require a minimum winter temperature of about 10° C. (but can resist for short period to 0° C). Growth is rapid, and supports are needed for the stems. The half‑erect habit of the moderately tall plants makes them desirable for middle foreground position in landscap­ing, while the comparatively small room needed for potted plants makes it an acceptable group for greenhouse culture.

Propagation: By cuttings.
