DUST grows on the North side of the silk plants.
I consider North to be at the top... and East is on my right, and South is... well you get the picture.
I only mention this because dust has been "growing" on the North side of my silk Foxglove plant. When I first noticed this I thought... cute, just the realistic touches that were meant to be there... like the cute moss on the pot.
this post when a "little birdie" told me...
"There really is dust on the leaves."
