Turns out, they thrive in cool weather. Our house, with the thermostat set to 70 degrees was, apparently too warm for it. Weird, right? This is how it is described:
Locate the plant in a cool room where temperatures are near 50°F to 55°F at night. Provide bright light but not direct sunlight. Excessive heat or dry soil can cause rapid decline.So...off to the basement it goes. On a ledge on the south side of the house to get some of that light. But...NOT direct light. I'll keep an eye on it and see what happens. Seems to not be the best flower for TJ's to be selling if it is going to be so temperamental.
