There is something about a perfect sphere: so geometric, so clean, so mathematical, so sculptural. They can't help but dress up a landscape.
I love sphere shaped plants in a modern landscape in perfect rows with some space in between the plants so that you can really clearly see the round form. I also love them in planter pots that share their curves (especially if the pots are the most basic of colors: black or white, with smooth sides. You don't want any texture to draw your eye).
Here are a few of my favorite spheres, from top to bottom: Barrel Cactus (Echinocactus grusonii), Hedgehog Agave (Agave stricta), Dasylirion wheeleri, Sedum 'Lemon Coral', Buxus sempervirens trimmed as a topiary sphere, and Pittosporum tenuifolium 'Golf Ball'. Golf ball stays very close to a sphere all on its own, so it is quite low maintenance. All of these will be happy campers in most parts of San Diego county.
