Sunflower 'Hopi Black Dye'

Try to plant in a location that enjoys full sun and remember to water often. Keep in mind when planting that Hopi Black Dye is thought of as half hardy, so protect with a row cover whenever the temperatures drop. Hopi Black Dye needs a loamy and clay soil with a ph of 5.7 to 8.1 (weakly acidic soil to weakly alkaline soil).

Try to aim for a seed spacing of at least 4.68 inches (12.0 cm) and sow at a depth of around 0.49 inches (1.25 cm). Soil temperature should be kept higher than 13°C / 55°F to ensure good germination.

By our calculations, you should look at sowing Hopi Black Dye about 21 days before your last frost date.

Ensure that temperatures are mild and all chance of frost has passed before planting out, as Hopi Black Dye is a half hardy plant.

Heirloom sunflower from the Hopi nation of Native American tribals.

The botanical epithet is from the Latin annuus meaning “annual”.¹
