Monvillea spegazzinii f. crested monster

The shape of this plant recalls a coral, thanks to its wavy greenish stem, which with the prolonged exposure to the sun takes on a beautiful purple color. Along the crest there are small spines, covered with a white down. The crested form hardly blooms, however the flower can bloom from non-crested stems. The large flowers, more than 10 cm long, open up at night. Synonym: Cereus spegazzinii f. cristatus monstruosus.
