Plectranthus 'Mona Lavender.' It had recovered well from its' near-death experience inside last winter, blooming well, but just kind of fizzled out. Declared officially dead about 3 weeks ago, but it was probably at least a month. I don't even have a theory why.
Epiphyllum oxypetalum (queen of the night & so many other common names.) Something keeps munching it as fast as it can grow. Needs a totally new situation next summer.
Birdnest fern (Asplenium nidus.) Nowhere near dead, but not back to the glory of last summer. Hung in same summer spot it loved last year. Wondering if getting too dry a few times over winter is more serious than for other plants. Will try to pay more attention this winter.
