Adrienne,

I hope that my response will be of some help. I have had several requests this year for pawpaws that are hardy in zone 4 but really can't answer that question with any personal experience. I do know that there are several locations of pawpaws being grown in zone 4 but do not produce fruit with any regularity. If the growing season is long enough then fruit has a chance to ripen. Several ways have even proposed to develop pawpaws that would be hardy but it would still be years away from fruition. There are a number of "hardy" named cultivars of pawpaws in the trade - NC-1 (Campbell #1, Canada's Best) is a cross between Davis and Overleese and was developed in Ontario. Davis is from Michigan as is Taylor and Taytwo. Unfortunately, these cultivars are not grown on their own roots.

I don't know of a source for pawpaw seeds from zone 4 but I would suggest that you speak to Ernie Grimo of Grimo Nut Nursery. They do have a web site. He is in Niagara-on-the-Lake, Ontario. He may know of a source for wild pawpaw seeds. Since you are looking for a source of pawpaw seeds that would be hardy in zone 4, I would suggest that you purchase or collect seeds from a source in southern Ontario.

The pawpaw seeds should have been cleaned, some moist peat, vermiculite or sand added, and placed in a refrigerator. The seeds need several months of stratification to germinate. For further information on pawpaw seeds, visit the OPGA web site, Ohiopawpaw.com, and you can download a publication on pawpaw Seeds.

I am looking for help in finding the most cold hardy Asimina triloba
seeds possible. Can anyone point me in the right direction? Also, what
would be the best time to order seeds to have them arrive safe &
viable?
The lone pawpaw that germinated from a packet of seeds purchased years
ago (don't remember where) has survived in a protected area for at
least 7-8 years but hasn't grown much. There is too much competition
for moisture with the mature white pine & basswood on either side.
After growing & planting more trees on the property, there are other
suitable sites available now to plant more pawpaws. Not really for
proper fruit production, just bragging rights for having "out of zone"
trees.
