This is a rare look at Worsleya procera - the legendary "Blue Amaryllis" with huge, bluish blooms.  Rarely seen for sale, this incredible Hippeastrum relative is endangered in its homeland of Brazil, where it is found hanging from remote cliffs near waterfalls.  This is a challenging plant to grow, but if you can provide the right conditions, it is a treasure.

 Worsleya procera (also called Worsleya rayneri) is an evergreen, bulbous plant that typically grows 2 to 4 feet tall, but occasionally to 5 feet, making it one of the largest plants in the Amaryllis family.  It has unusual, arching leaves that resemble a rooster's tail.  The plant generally flowers in the summer, and its stalks can have 7 to 14 blooms, each about 6 inches across.  The flowers are a breathtaking lilac-blue color that blends to white in the center.  The plant has been disappearing quickly in Brazil and there are only few colonies left.

Worsleya comes from a part of Brazil with moderate temperatures and cooler nights, similar to San Diego's climate.  There are reports that it is difficult to grow in temperatures above 90 degrees F (32°C), especially if nights are warm.  It is happiest with cool nights (below 65°F / 18°C).  It can tolerate a light frost, but i recommend keeping it above 35 degrees F (2°C).  It grows well indoors in a sunny spot.

The key to growing Worsleya successfully is to provide the right growing medium.  It needs very fast drainage, to simulate the rocky slopes of it's habitat.  It should not be grown in soil.  Good mediums include lava rock, pumice, or other porous rock, about 7-10 mm in size.  For moisture retention, a small amount of coconut husks, peat, or fine orchid bark may be added.  Some people have had success growing it in 100% long-fiber sphagnum moss.  The medium should always be kept moist, so it might need daily watering during summer.  It likes mostly-sunny conditions.  Some afternoon shade might be needed in warmer areas.  More tips on growing this plant
