This is our workhorse green zucchini, the same we grow on the farm. It has great great resistance to powdery mildew.
Please note the white leaf markings on Dunja zucchini, this is normal on this particular variety! We've had people wonder if this is powdery mildew. It is not, actually Dunja is more resistant to mildew than other varieties. It is what we grow on the farm. It still will develop mildew eventually but last much longer. If you want zucchini till fall plant a second succession mid summer. You can see the difference between Dunja zucchini leaves and sunburst patty pan in the last photo.
