Plant Common Name

Mexican Zinnia

General Description

A lover of sunshine and heat, Mexican zinnia is easy-to-grow, tough and produces lots of golden orange daisies all summer long. This pretty, bushy, warm season annual is a native of Mexico where it thrives in hot and even dry weather.

Mexican zinnia has a low, bushy, erect habit and linear, green leaves. Blooming begins in early summer and will continue to frost if the flowers are regularly deadheaded (cut back when spent). In tropical and subtropical regions it can be planted year round. Its pretty orange to golden orange daisies are typically single, though cultivated varieties tend to have double or semi-double flowers that come in a wider variety of warm colors. The blooms are very desirable to butterflies and will bloom well all season without deadheading, unlike other zinnias. The fruits/seeds are short, dark, flat and germinate readily.

Mexican zinnia grows best in full sun, average garden soil with adequate drainage and will bloom only six weeks after sowing. It thrives when temperatures are hot, especially if provided regular water. As the summer wanes, most zinnias develop the foliar fungal disease, powdery mildew, but Mexican zinnia is resistant. This butterfly magnet will add color to any border and is excellent for container culture.
