What plants like direct afternoon sun?
Sun loving coleus and bronze leafed wax begonias may work. Just keep the soil moist. Purple heart (setcreasea purpurea), pentas, and four o’clocks are other annuals to consider. For perennials try dwarf mexican petunia (ruellia), lilyturf, daylilies, and speedwell (veronica). Grow your perennial flowers in perennial beds around your raised-bed kitchen garden. Some of my favorite perennials are echinacea, bee balm, rudbeckia (aka black-eyed susans), anise hyssop, and salvias.
