Answer: Here are a few suggestions for heat tolerant plants:
Calylophus drummondii (Sundrops); grows 6" tall; intense yellow flowers in spring and summer; light green foliage. Cuphea x ?David Verity? (Firecracker Plant), grows 2' tall; small, bright orange, tubular flowers litlerally smother this plant. Blooms prolifically from spring until frost. Dark green, lance shaped leaves offer a cool backdrop to noisy display of flowers. Rudbeckia fulgida ?Goldsturm? (Black-eyed Susan) ; Bright, golden yellow petals surround a velvety browm center. Blooms from spring until frost. Verbena x hybrida ?Pinwheel Princess? (Pinwheel Princess Verbena); grows 2' tall; Clusters of tiny flowers shower these low growing plants. Each individual flower in the clusters are light lavender with white stripes down each petal. Look closely! As with all verbenas, Pinhweel Princess offers the best show in spring and fall with a few flowers in the summer. Echinacea (Purple coneflower); grows 3' tall; Purple, daisy-like petals gracefully fall away from orange cones on sturdy stems. Spring and fall see the best blooms, with sporadic bloom in summer. Deadheading prolongs bloom time. Erythrina x bidwillii (Coral Bean, Fireman?s Cap); A very tall plant; Bright red flowers are borne on racemes of a foot long or more from late spring until fall.
