Alice, in my area, the drasticaly price turning, and the booming of plant collecting trend was strated around march 2020, soon after the pandemic. So I believes this is due to people get so depressed by lock down and social distancing
The other phenomena been depressing is plant stealing from home collection, this force us to cage our plants, it happens in the past but increasing as the price climbing.
This is why I feel unsettle accepting people visiting my "green house"
Yesterday few people come by, and one of my plant dissapeared
It is so coincindential that it was a half moon foliage
a Schismattoglottis sp from Borneo
Unfortunately that is the only plant ever been found by my friend in Borneo. There is no other, and I lost it before I had a chance to propagate
