FORECAST: My guess is that houseplants are going to be the popular hobby in winter covid. Plants are to winter-covid as bread-baking was in spring-covid.
I was at a hardware store recently, and the garden section was still hopping despite being out of season here.
Loads of friends are currently picking up green friends to keep over the snowy months. Most of the local plant shops seem to be low on stock.
An artist I follow recently did painting of a plant that they wanted to trade for cuttings of said plant.
