Title: House orchids 2025
Post by: ashley on February 17, 2025, 02:31:53 PM
These Sophronitis (now Cattleya) are hardly relevant to rock gardening in temperate climes, but grow on moss-covered rocks and trees at altitude in SE Brazil.

Apart from their intense colour, the tepals of S. mantiqueirae have a lovely crystalline quality rather like Nerine sarniensis that I find hard to photograph. 
In any case they brighten up dull winter weather here.

Beautiful flowers, do you have to heat during winter?

These live in the house year round, but in good light and a cool room with temperature usually in the range 10-20°C.

I have a few Phalaenopsis. The leaves have white spots on both sides. Is this a disease or a watering problem. I have wiped the leaves with a paper towel with white vinegar but the spots have returned. The "spots" look like wooly aphids but no insects seen. Any suggestions welcome.

Try wiping a trial leaf with Neem Oil.

Ashley, true gratrixianum has leaves up to 6 cm broad and was only rediscovered recently. Your plant, the"false" gratrixianum, has been renamed christensonianum.

Thanks Herbert; label corrected.
Leaves on this plant are only about 2.5 cm wide.
