Maximilian sunflower is an excellent multi-purpose permaculture plant. It's a late bloomer, making it an important nectar source for pollinators late in the season. It can grow up to 8 feet tall in ideal conditions, making it an excellent privacy screen or wind break. They like moist but well draining soil in full sun.

The seeds are small, but edible. The plants are quite deer resistant. The roots form a thick barrier that can keep grass from creeping into a garden. Toby Hemenway calls them a "fortress plant."

Plants eventually grow to form a patch that produces a lot of biomass useful for mulch and composting.

50% of sales from this variety go to Sovereign Seeds, an Indigenous-led initiative dedicated to the revitalization of Indigenous seed and food sovereignty in so-called Canada. 

Growing Instructions

Direct sow or in pots in fall or early spring. Seeds benefit from some cold stratification.
