This is exactly what has fueled this craze. And influencers on sites like Youtube...some people complain that everyone certain 'influencers' even ***mention*** a plant, the price triples.
I had a few friends who went to the IAS show this year and were totally disappointed (just like last year)...it was crowded with 'new' collectors, so crowded it was almost impossible to shop, the prices were inflated, and there was a definite lack of 'rare' plants and a total overstock on 'trendy' plants
