I am lucky enough to have a tiny garden at my apartment and the free reign to do whatever I want! My ideal is a true California native garden with fruit trees and herbs but I make do with drought tolerant plants (propagated from mom & dad's), wild plants and existing landscape. No space for fruit trees but I can do herbs....
Dwarf culinary lavender
Herb garden planter: mint, parsley, basil & rosemary
Easy project - natural plant markers!
Smooth stones (I found mine on the beach)
Rubber alphabet stamps (typewriter)
Permanent ink stamp pad
lavender + A initial
To spruce up an otherwise drab apartment entry, I added two large containers with yellow/red kangaroo paws (drought tolerant, especially by the beach) and a railing planter with my dwarf lavender.
The walk between my front garden and my door was pretty boring. These little CB2 candleholders (at only $1.95 each) with tea lights make add interest while serving a purpose (the lights help guests find my tucked away apartment!)
