My Catasetum Saccatum orchid in bloom for the first time another spike is coming. Grows in filtered sun under a large oak tree for most of the year on a cork mount. The rest of the year it is inside under grow lights when in bloom or outside in a polytunnel greenhouse with a heater. I also own a Catesetum Incurvum I will post pictures of that in the comments, and you can see how the flowers are close yet different. I found the Saccatum flowers were larger and the frills were different. You can also see they have longer petals.
