Miltoniopsis, commonly known as ‘pansy orchids’ because of the similarity of the flowers to pansies, is abbreviated Mltnps in horticultural trade. It consists of 6 species, native to Costa Rica, Panama, Venezuela, Ecuador, and Colombia. They are named after Lord Fitzwilliam Milton, an English orchid enthusiast.

They differ from Miltonia by having one leaf to each pseudobulb, and a lobed column that is united to the labellum through a keel. In addition, the column is not concave at the base.

The six species of Miltoniopsis:

  • Miltoniopsis bismarkii
  • Miltoniopsis phalaenopsis
  • Miltoniopsis roezlii
  • Miltoniopsis santanaei
  • Miltoniopsis vexillaria
  • Miltoniopsis warscewiczii

Culture

  • Temperature: Intermediate to cool temperatures. Daytime highs should not exceed 80F. However, they will acclimate to both lower and higher temperatures over time.
  • Light: Bright intermediate light (1800-2500 footcandles or about 75% shade. The leaves of Miltoniopsis should be grey green and can even show a touch of pink when they are at their upper limit of light.
  • Water & Humidity: Miltoniopsis like to be evenly moist. If kept too wet, the roots will rot. If they are too dry, they will dehydrate and die. They benefit from 40-60% humidity, and excellent air movement. One unmistakable sign of insufficient watering is horizontal, accordion-like pleating of the developing new growth.
  • Fertilizer: Use a balanced fertilizer applied at half strength every other watering or a good timed-release product. Miltoniopsis are sensitive to salt buildup. Alternate feeding with a couple of heavy waterings to flush out the salt.
  • Potting: The roots of Miltoniopsis are fine, requiring a fine potting mix. Many growers use a mix of fine firbark, perlite and charcoal although any good fine-grade epiphytic mix should be adequate. They should be repotted every year after flowering, as they are very sensitive to the breakdown of the mix.
