Nice idea on the reflective material on your outdoor pots! In our cold climates it works to start out with dark or black pots for early season warmth, but they do tend to dry out fast in high summer. What material are you using for the covers?
You really had me fooled in your very first picture! I thought that was a lovely tall ceramic pot and was coveting it! Only after seeing these last pics did I figure out was it was - looks great!
