Ceratostylis rubra: an amazing ruby orchid

Do you like rubies? I think the best ruby for an orchid lover is flower of Ceratostylis rubra. This ceratostylis is a miniature orchid with thin sharp leaves and red-orange flowers. They are tiny but very colorful. Flowers of this mini orchid shine as small ruby stars. Today I'm going to tell you about how to grow Ceratostylis rubra indoor.


Ceratostylis rubra

I've consulted about care of this flower with Denis Silchenko (mail: dem4ig@ukr.net), who is a collector of rare orchids. Denis has many unusual plants at his home. I will tell you about another miniature orchids from his collection in my next posts. However today our hero is Ceratostylis rubra.

This floral character prefers high humidity (near 80%). Therefore Denis recommend to cultivate Ceratostylis rubra in a mini orchidarium. If you decide to grow your green pet on a windowsill, you have to add moisture to the air or else the plant may die. This green person is afraid of dry air.

Also this ruby orchid likes bright diffused light. It needs sun ray in morning or in evening. Nevertheless if you grow the mini plant on a southerly windowsill, you have to shade your flower at noon. 

In addition this mini orchid demands temperature drop. Difference between day and night temperatures should be 41-44.6 degrees Fahrenheit (5-7 degrees Celsius).

Watering of this plant should be very gingerly. Ceratostylis rubra doesn't stand over watering and under filling. The substrate should always be slightly wet. 

As a lot of tropical orchids, the plant loves warm wind but doesn't bear cool draught. Many flower lovers grow this "ruby star" near a fan. My consultant makes wind for his orchids by the instrumentality of... computer coolers.


If you cultivate the ceratostylis on a windowsill you may plant it in a pot. However if you grow the orchid in a mini orchidarium, block planting is correct for this mini houseplant.
