Though sunlight is a crucial part in plant development, many plants wilt when exposed to a full day of sunlight, leaving the gardener with an unattractive and drooping flower bed. However, there are many plants that tolerate and flourish in full sunlight, producing better blooms in all-day sun than they would otherwise with partial shade.
Native to Mexico, Mexican zinnia (Zinnia haageana) is a low-growing annual that offers attractive gray-green foliage accented by daisy-like orange or white blooms. The plant is popular for flower beds thanks to its lovely flowers as well as its extremely high tolerance of both drought and heat; this annual won't even wilt in the brutal Southern summers. Mexican zinnia requires full sunlight and well-drained soil.
As tough as it is beautiful, blanket flower (Gaillardia pulchella) is a flowering perennial or annual that produces brilliantly-colored, daisy-like blooms in shades of yellow and hot pink. Native to North America, where it is particularly common in the Southwest, blanket flower is a hardy plant that grows in abundance in poor and sandy soils. Blanket flower prefers full sun all day long, and the plant has a high drought tolerance. Soil should be well drained.
Cape lily (Crinum X powellii) is a striking hybrid of two native South African lilies. The perennial plant produces fragrant, slightly-tubular pink or white flowers throughout late summer and autumn. Though Cape lily will tolerate partial shade, it produces its best blooms in full sunlight. Cape lily grows best in fertile, humus-rich soils that are kept moist, but not overly wet. Like all Crinum lilies, Cape lily is poisonous if ingested and should be handled with care, as the sap can be a skin irritant.
