I've loved these geometric lead light terrariums forever. I remember a family friend had one at her house and I'd stare lovingly at it when she was looking after me. I quite like the way they're displays on these tiered shelves too.
Grow a lemon plant indoors. Apparently lemon leaves smell good. Soak lemons seeds overnight. Gently remove outer layer of seeds. Put back into water as you prepare soil. Plant lemon seeds in a circle pattern. Place small pebbles on top of seeds. Water occasionally and watch it grow.
