Zinnia Double Mix Seeds (Dahlia-flowered)

Zinnia Double Mix packs the layered, ruffled look of dahlia flowers onto one of the easier annuals you can start from seed. It's a solid pick if you want fast, reliable color on a sunny balcony rail or terrace bed, and the double blooms hold up well once cut, so you can bring a few stems indoors without stripping the plant bare. Give the tray a warm spot and don't let the mix dry out - germination lands in the 5-7 day range, quicker than most flowering annuals. Once seedlings are up, thin or transplant them so each plant sits 20-30 cm from its neighbours; zinnias branch out as they grow and get crowded fast in a tight pot. They want full sun, 5-6 hours a day, and only need water once the top layer of soil feels dry. From sowing to first flush of flowers is about 55-70 days, and since the plant needs no staking, it stays low-maintenance right through to harvest.
