Wedding Ring: This one. White gold band with a rose gold halo setting. Skinny band (but not too delicate that I would have to be careful with it). Maybe a light champagne center diamond, or else just a normal diamond.
Dwarf New Zealand Tea Tree [Leptospermum scoparium 'Nanum Ruru'] -- Most Leptospermum are big upright plants, but this charming short-statured cultivar is one of the few that fits into city gardens. Blooms in spring, drought tolerant once established.
