The Center for Urban Horticulture Miller Library used to compile a list and have it on the front counter as a printed handout. Pretty sure it was also put on their web site. Maybe they are still doing this.

The list you have already may be as big or bigger than the one they put together.

Maybe you have to file a brief first.

lawyers switched their link to html and i got a gander at the fruit list.

it was definitly worth the wait and would be worth filing a brief just to be prepared.

lots of trees i can easily pick 20-25 i wish to add. would like double that many more but alas i must round-up the fencing before i make my purchase. still have 8 more trees from burnt ridge to plant before this event.

montmorency cherries are a big time need for me and i want at least 5 maybe 10 this year. i absolutely crave cherry cider and juice ,but the pure thing is next to impossible to buy commercially. next year i believe i will look for 5 english morellos for mixing and the color.

at these prices i think i will start digging holes on the 1st of may.
