Masdevallia datura

Masdevallia datura is named for the enormous Angel Trumpet flowers belonging to the genus Datura or Brugmansia.  Its flowers are nowhere near the size of the Angel Trumpets but are large for the size of the plants.  The plants of this Masdevallia are 12-15 cm tall, with narrow leaves and flowers, measured from tip to tip that are as large as the plant.  The species is from Bolivia and is cool growing.  It is not a prolific bloomer for me, but has done better since I reduced the light, cut back fertilizing to almost nothing, and let it dry out a bit more between waterings.
