My favorite houseplant right now is the calamondin orange.
DH bumped into it today and asked me if it was a tomato plant.
You have to excuse my non-gardening, color-blind DH.
I had him taste one of the ripe oranges and he loved it! They're delicious but too tart for me to eat straight.
When you have a SO who grumbles about the houseplants taking up too much space, it's good to have one that literally amazes him!
