What to plant in VERY tall, narrow planter
I have a beautiful glazed blue pot. It's 22" high, with an opening at the top of 5", but the pot itself is about 9" in diameter. It's urn shaped, tapering ever so slightly towards the base. It's been sitting indoors for years, used as an umbrella stand, but I really want to find a use for it in the garden and thought it would be a good idea to find a plant that really needs that sort of depth for its roots. I know I could just stick a geranium in there (just an example!) but shallow pots are so easy to find, I want to make the most of this beauty.
We have a sheltered garden and because the pot is tall no matter where I place it it's likely to have sun for at least a few hours a day. It could also be placed full sun.
