Who developed it, what it is, whether you are free to propagate it, and where to find it.
A named cultivar is shared inheritance or someone’s property.
The difference decides what a grower may plant, graft, and pass on, and it is rarely printed on the tag. This is an open record of both kinds: cultivars filed by habit, use, and species, each one carrying who developed it, what it is, how it may be propagated, and where to find it. Every entry cites its source. A field nobody has sourced reads not recorded rather than a guess.
Trees nut-bearing
01
Chestnut
A nut-bearing tree genus whose named cultivars are documented across American, Chinese, European, and Japanese species and their hybrids.
02
Hickory
Pecan’s harder relatives — a short list of named clones, most of them found by one person walking one woodlot, and a collection with a documented history of mistaken identity.
03
Oak
The least domesticated of the temperate nut trees — a genus with a long list of named cultivars, almost none of them selected for the acorn.
04
Pecan
The most thoroughly documented nut tree in North America — a federal collection, a breeding programme running since 1930, and a cultivar list a grower can actually trace.
Trees fruiting
05
Mulberry
A reliable, generous fruit tree with the least reliable names in this database — and one design decision a grower near remnant native populations should make deliberately.
06
Pawpaw
The one temperate member of the custard apple family — a native understory tree whose named cultivars come from two breeding programmes and a handful of wild finds.
07
Persimmon
A fruit whose cultivar records turn on two questions a tag rarely answers: whether it needs a male, and whether the fruit is edible firm or only when it has gone to jelly.
