Knock yourself out. The worse thing that could happen is that the pears taste bad.

I tried leaving pear trees that came up from seed, under our rusty coated bartlet pear tree. None of the ones came close to the brown rusty coat that was the parent plant, which even had limbs that had green color pears on them. I always wanted another tree of them but never found them even listed. I've also wanted to try apple seeds but was told they don't come true....

The thing about doing seeds is you won't find out what you get for years and years.

Last winter I winter sowed 5 Dwarf Keiffer Pear seeds I received in a trade. I had 3 sprout in the spring. I planted them and now they are 18" tall. It's like Wantie said you won't find out what you get for years and years.

A couple of years ago a cousin discovered a pear just like the one you are discribing. Small tasty pears that after a little research we decided were like a seckel pear. Two neighboring pear trees have also obviously come up from seed .. One has a tiny bitter pear.. The other a medium sized bitter tasting round pear..

I collected seeds from the small sweet pear to grow some trees from seeds. I thought out of about 50 pears seeds I would have a couple germinate (this was after cold stratification in a refrigerator with a moist paper towel in a closed container) . I started them in a green house in early Spring. I came up with 47 baby pear trees.. Not thinking that any of them would germinate I just layed them out in one pot.. I then put each one in a gallon container. It took me awhile to peel them all away from each other.. They all survived..

I have been amazed at the differences in the growth habits and leaf patterns of each one.. anything from light green leaves to maroon.

Now my plan is to use some of them as rootstock and graft a nice tasting pear on the top of my little baby pear trees, and also to get some scion wood from some of the older pear trees in my neighborhood..

All in all , I'm having great fun with my little experiment. The seeds were free.. and after pricing some rootstock I feel pretty good about it. Now, whether I will live long enough to eat a pear off one of my trees remains to be seen.. It's also been a great conversation piece. Now where to plant 47 pear trees?
