Tolerates Drought
Garden stalwarts, zinnias have been a favorite for generations. They're a snap to start from seed and their bright colors are wonderful for late-summer bouquets. Dwarf types grow just 6 inches but others can grow up to 3 feet. Zinnias are ideal for attracting butterflies, who feast on their nectar. Common zinnia (Zinnia elegans) is the best known but narrow-leaf zinnia (Zinnia angustifolia) is quickly gaining in popularity because of its low, sprawling habit.
Notable Varieties
Zinnias are available in a vast, and ever-expanding universe of sizes, colors, and styles. A few notables include:
'Dasher', 'Dreamland', and 'Small World' are desirable dwarf bedding forms.
'Blue Point' and 'Ruffles Hybrid' are tall varieties especially well suited to cutting.
'Envy' has bright green flowers.
'Peppermint Stick' has red and white streaked flowers.
'Big Red' is mildew-resistant and a wonderfully rich red; grows about 3 feet tall.
'Profusion' series are compact bushy plants in a range of warm colors.
Care
Likes rich, well-drained neutral to acidic soil. Does best with moderate moisture but drought-tolerant if necessary. Fertilize by working in compost two or three times during the season or by applying a slow-release fertilizer, following label directions exactly. Mulch to conserve moisture. Deadhead regularly.
Planting
Zinnia prefer to be direct seeded into the garden after all danger of frost has passed. Nursery starts can be set out at this time, also. Or, sow seed indoors 4 weeks before your region's last frost date.
Pests and Diseases
Mildew, especially in the Midwest and Southcan be a problem. Seek out mildew-resistant varieties and avoid wetting leaves when watering.
