  Echinopsis Oxygona
(Syn: E. multiplex)
CACTUSPEDIA       

 


The flowers of Echinopsis oxygona are truly beautiful.
[Photo and plant by Massimo Giannelli Italy - Click to enlarge]

Description: the stems is  globose to elongate up to 30 cm high with 12- or 15-ribs. The areoles have 0,5-2,5 cm, curved, black-tipped brown spines. Needs little water when established.
These cacti grow rapidly and forms big clumps up to 60 cm in diameter and produce gorgeous, night-blooming, white-to-pink funnel-shaped, fragrant flowers with long tubes 15-20 cm long. Old plant may have dozen of stunning flowers open at a time. This species blooms from late spring to all summer long, the flowers open before sunrise but last only one day in full beauty, at the second day they start to wither. This plant has been widely crossed with other species of Echinopsis and the number of cultivars seems unending. The flowers are lovely and are available in an assortment of bright colours ranging from magenta, red, orange, to yellow, and much sought-after by Cactophiles everywhere.



 

Cultivation: The Easter Lily cactus is a summer grower species that offers no cultivation difficulties.  Water regularly in summer (but do not overwater ) needs good drainage and very porous soil,  keep rather dry in winter. Feed with a high potassium fertilizer  in summer. It is quite frost resistant if kept dry (hardy to  -7 C).  Need a bright exposure, full sun or half shade in summer.

Propagation: Direct sow after last frost, offsets.

The cacti that love hawkmoths pollination.
Many species of cacti
utilize hawkmoth pollination and depend on hawkmoths for successful seed production. This species (Sphingophilous plants) are easily recognized for the  white trumpet nocturnal flowers  (e.g., Echinopsis multiplex, Acanthocereus tetragonus, and Hylocereus hundatus) whereas others are more tubular (species of Selenicereus and Stenocereus eruca).  It is unlikely that only one moth species is pollinating only one flower species, so there will be mixed pollen grains of many species on the insect. That notwithstanding, hawkmoths are credited as fairly reliable long-distance cross-pollinators because they are able to carry even small amounts of pollen to isolated, self-incompatible plants in tropical areas to produce fruits with viable seeds.
Sphingophilous flowers are largely unused by other classes of pollinators. These nocturnal flowers are unavailable to day-active pollinators until the next morning, and, in fact, bees of various types sometimes arrive during morning hours to accomplish an even higher level of pollination success.
