Zahara Series Zinnia is a compact annual flower that brings reliable, brilliant color to gardens across zones 3-10. This cultivar earned its reputation through genuine performance: it won the 2010 AAS Bedding Plant Award and 2008 Fleuroselect Novelty Award specifically for superior disease resistance to leaf spot and mildew, traits that matter when you're trying to keep plants thriving through summer heat and humidity. Reaching just 12-18 inches tall with a tidy, mounded form, it flowers in 50-59 days and thrives in full sun, making it a dependable choice for beds, borders, and containers where other zinnias might struggle.

These zinnias earned their accolades because they actually perform where other ornamental plants falter. The Zahara Series stands apart for its compact growth habit and exceptional disease resistance to leaf spot and mildew, two problems that can turn zinnia beds into disappointments by late summer. In trials and gardens, they deliver long-lasting blooms without the typical deterioration that plagues other varieties, and their smaller stature keeps them neat without constant pinching.
Zahara zinnias thrive in summer flower beds, container plantings, and mixed borders where their compact form and reliable color make them workhorse annuals. Their disease resistance and tidy habit also suit them to display gardens and public plantings where consistent appearance matters throughout the season.

Start seeds indoors 4-6 weeks before your last frost date. Sow seeds on the soil surface or just barely covered, as they need light to germinate. Maintain soil temperatures around 70-75°F for best results. Seedlings will be ready to transplant outdoors once they have their first true leaves.
Harden off seedlings over 7-10 days before moving them outside. Transplant after your last frost date when soil has warmed and nighttime temperatures stay above 50°F. Space plants 18 inches apart to ensure adequate air circulation, which supports their disease-resistant qualities.
Direct sow seeds outdoors after your last frost date once soil has warmed. Sow seeds on or just barely beneath the soil surface, keeping the area consistently moist until germination occurs.
Deadhead spent flowers regularly to encourage continuous blooming and maintain the plant's compact form. Pinching the growing tips early in the season can encourage branching if you want a bushier plant, though the Zahara Series naturally grows in a tidy mound.
