Vanda (VAN-duh) or Ascocentrum (as-koh-SEN-trim)
Vandas are large plants that need full sun. Ascocentrums are smaller, and need a little less sun. These come in blues, purples, whites, reds, oranges, and yellows.
These need sun, warmth, and high humidity.
Provide lots of water and fertilizer. In the summer, Vandas need to be watered daily.
Give them less water and fertilizer during winter dormancy.
Both kinds dislike repotting, and are often grown bare-root, without potting material. They can also be grown in small hanging baskets with their roots hanging out in the air.
