Here is a plant recommendation for you...Greyzini Zucchini
In the past I have grown the black variety.
I have found, that like many of their squash cousins
they produce an abundance of male flowers first.
Only much later do the female flowers appear.
The result being a longish wait for the first zucchini.
Well not in this case.
As soon as it began to bloom
the Greyzini produced both male and female flowers.
The zucchini have a lovely patterned skin...not really grey.
This early fruiting is not just an aberration isolated to my garden, because my sister's Greyzini is also a precocious producer.
It will be interesting to see how long the plant lasts and if it will continue to fruit as long as the black variety.
