I ordered two bunches of Spanish Moss from a vendor back in December and it hasn't grown a single bit, but it flowered during the summer. It is the thick variation of the species, not the thin. It is definitely alive, kinda greenish-gray... I really like the look it adds to my greenhouse and I want it to grow so I can decorate with it, but it just won't grow at all! My humidity has been 90% at night and anywhere between 50-60% at the hottest part of the day, and now it is 70% at lowest during the day with my new swamp cooler. I used to mist it and fertilize it, but I stopped months ago after no apparent growth. It is in my highland greenhouse growing with my neps, so it gets natural sunlight.
What can I do to make it grow? Also, is the packaged Spanish Moss that they sell at Home Depot or Lowes living, or is it dried? It looks the greenish-gray that living Spanish Moss does.
EDIT: Nights between 50-60F, days between 70-80F.
