Coreopsis adds a lovely bit of color to the garden.  These are tough plants that need little to moderate water and they seem to bloom almost endlessly, especially if deadheaded.  They also tend to self-sow, so be prepared for either even more color or a bit of weeding.

Tulbaghia, or society garlic, is an evergreen perennial with narrow green or green and white variegated leaves.  Clusters of small lavender flowers top stems that are one to two feet tall.  Provide regular water.  Because of the garlicky odor of the leaves, deer tend to leave it alone.

Phlomis, or Jerusalem sage, is not a true sage, but it has similar requirements.  It needs little water, good drainage and is tolerant of heat.  Leaves are woolly and flowers can be either yellow (P. fruticosa) or pink (P. purpurea).  Phlomis generally grows to about four feet tall and wide.
