Angraecum sororium

Mine is outside nearly 8-9 months per year, in full sun.
It can support a big range of températures, near from 0° in winter but with no watering and nearly 35-40° in summer but with a dayly watering!!

 

I grew wild collected Ang. Sororium in a variety of mediums and had excellent results with wide plastic pots containing small chunks of quartzite/granite in the bottom with several inches of African Violet mix on top. The plants potted this way were kept evenly moist and never allowed to dry, they grew extremely well with a significant amount of root growth and suffered no dehydration during our hot summers here in N. Texas. The only issue was the need to water daily and shelter the plants from direct sun in the summer due to high ambient temps.

I noticed the tag on your plant, how long have you had your specimen and where was it purchased?

 

nice

 

It can handle the heat -- they are incredibly tough. The trick, though, for blooming is that they MUST get very cold. I take mine outside in the fall and it stays there most of the winter--unless temps will get below 30 degrees. (It is on a covered porch so it doesn't get frost etc -- and I'm sure the house radiates some heat. ) These plants can handle both extremes of temperature -- and will grow fine without the cold. But it must have the cold to bloom.
