I just purchased four, deep red, square, 30" tall( top diameter 14", bottom 10"), planters. We live in the Bay Area (Sunset 14), but the planters are shaded after 10am each morning. I love the planters, but I'm a newbie at gardening so I'm at a loss as to what to plant. I love color and would ideally like to have some color (at least leaves) year-round. Does anyone have any suggestions on what to plant? Thanks so much for any ideas.
