They do not stand direct sunlight, but without sufficient sun exposure, they don't bloom. As a matter of fact, i grow them like other vandas or cattleyas.
Never heard of it..thanks to bringing another orchid to my attanetion.
Christensonia vietnamica is a relative new species found in southern Vietnam.
Recently, it is used to create new hybrids with other monotypic species, such as Neo. falcata or Aerides species.
