Lee,
The only male arguta in my local area is mine, it is small and it does not bloom. I can assure you that Issai is self-fertile. I eat the fruits in good years.
Perhaps there is some biological issue (soil?) that prevents some Issai from fruiting or perhaps there are different strains sold under the same name, some self-fertile and others much less so. But I am certain that mine produces fruits without a separate pollinator. I once had 5 or 6 different female varieties of arguta, but have since given up on them, as I do not have a lot of space and the male refuses to flower in its allotted space. I have cut them all back or dug some of them out, due to their non-productivity.
John

Once Actinidia establishes itself, it seems to increase in cold hardiness and resistance to late spring frosts, perhaps by creating its own microclimate. I also protect mine by wrapping them in their early years.
Usually, it does take about 8 years before A. arguta flower, but I do have one 'Anna' plant that started bearing after 3 years.
Actinidia kolomikta, which also bears delicious fruit, typically starts bearing only a year or two after planting. It's also much less vigorous (which is good) and ripens about a month earlier than A. arguta. Unfortunately it begins growth earlier in spring so is
somewhat more subject to late spring frosts. The males have beautiful, variegated, silvery pink leaf color. Issai may be a hybrid of the two species. Despite claims, I found it to be little or not at all self-pollinating.
And now for a commercial message: All this information, and much more, can be found in the Actinidia chapter of my book Uncommon Fruits for Every Garden. The book is available for sale (from me, through my website, among other sources) but is also available at the NAFEX and many other libraries.

It needs significant protection the first few years, especially from the sun and wind. If you can find a special place, it might work for you. It seems to languish a few years, establishing roots and base stems, before it finally takes off.

Pat, it's all about getting a male/female match... the first 3 males I had didn't work so that chewed up 12-15 years of waiting.. the meader male
flowered in 3 years (not a lot) but I think by next year it'll really start putting out.

Issai hasn't made it in Zone 4b for me... I'd love to make that one work. On Thu, Sep 23, 2010 at 7:00 PM, John S <swim_at_svc@yahoo.com> wrote:
I dug out my biggest one I have this spring. Had it for 10 years and it only occasionally flowered. The male I have of the same age has never flowered.
However, I have the variety Issai that flowers and produces fruit every year. It is self fertile, but some years drops all the fruit before it matures. It is far less vigorous than the other ones I have.

I hope I don't have to wait
that long.....I planted my male and female this past fall.
