You only need one Pear tree (not a second pollinator) for the seclections I list below. Additional info: "...Take damp, heavy soil better than most fruit trees; resistant to oak root fungus. Good looking enough for garden use and need little pruning when mature, but require spraying for codling moth, aphids, and other pestes. Fireblight, which makes entire branches die back quickly, can be a serious problem. Cut out blightened branches well below dead parts; wash pruning tools with disinfectant between each cut. Train trees early to good framework of main branches; then prune lightly to keep good form, eliminate crowding branches. Pears on dwarfing understock are good small garden trees, excellent espaliers." Cultivars (for your area) 'Moonglow' - Wide climate tolerance; Somewhat like 'Bartlett' in looks. Juicy, soft. Flavor good. Ripens 2 weeks before 'Bartlett'; Tree upright, vigorous, very heavy bearer. Very resistant to fireblight. 'Seckel' ('Sugar') Widely adaptable; Very small, very swee, aromatic. Roundish to pear-shaped, yellow-brown. Flesh granular. Early mid-season. A favororite for home gardens, preserving; Tree fairly resistant to fireblight, highly productive. 'Sure Crop' Prolonged bloom period makes it safe bearer where spring frosts come late; Resmbles 'Barlett' in looks and flavor; Bears Aug-Sept; Consistent annual bearer. Fairly resistant to fireblight. Plum: 'Stanley' (European) Self-fertile; Large; pourplish black skin, yellow flesh. Sweet and juicy. Midseason; Good canning variety; resembles larger 'Italian Prune'. 'Sugar' (European) Self-fertile; Medium-size (somewhat larger than 'French Prune') Very sweet, highly flavored. Early midseason; Good fresh, for home drying and canning. Trees tend to bear heavily in alternate years. I'd also say 'Stanley' is a best choice. Additonal info: "Aside from Japanese and Euopean plums, there is a third category; important only where climate is unusually severe. This is a complex group of hybrids involving Japanese plum, several specis of native American wild plums, and the native sand cherry (P. besseyi). Originating in Canada,k the Dakotas, and Minnesota, this group is exceptionally tolerant of cold and wind. Typical varieties are 'Compass, 'Pipestone', 'Sapa', 'Sapalta', and 'Waneta'. The fruit can be eaten fresh, cooked, or made into preserves. Pollination is often difficult with these hybrids; ask local nurseries about effective and available pollinators." "European plums and prunes bloom late and are better adapted than early-blooming Japanese plums to areas with late frosts or cool, rainy spring weather." All this info and I agree, 'Staley' is a good selection for you. Sunset Western Garden Book (Fifth Printing June 1997); Sunset Books Inc, Menlo Park, CA; ISBN: 0376038519.

I do the same thing, Jim. I have been cutting all the seeds off so the plant will bloom longer, but plan to stop doing that soon, so there will be seeds. Each pod will have quite a lot of seeds. I have trouble getting them to germinate usually. Last year I was gone for a month, and came home to LOTS of seed pods on my yellow Datura (moonflower), so I cut them off and just threw them in a bucket that had holes in the bottom. NO DIRT. I thought I would discard them, but neglected to do so. This spring the 3/4 full bucket of seeds started to sprout! I just took the plants out and put them in dirt and more would sprout! There are still seeds in that bucket sprouting as I type. I guess when I don't try I get better results! LOL My white one doesn't have as many seeds, or blooms, as the yellow one, or the purple one. This year I may have a bucket for each color! Grin!

based on the nice hack tree next to it [love that bark] ..... i know whose butt the seed shot out of .. lol ... and i would bet on the seedy wild bramble varieties ... blackberry or rasp ... if you want some nice black or raspberries.... buy some good varieties .. and plant then in sun ... the ones the birds drop are usually very small berries.. with huge seeds ... both in size and amount ... all that said.. looking at the area in general ... if all your looking at is a natural area ... leave it there ... just dont bother moving it to prime space ... not many 'free' plants.. end up valuable ... ken
