This rare native tree has a problem. The mammoths are gone. Now there is nothing to eats its pods and spread its seeds, they just fall right under the tree, and without the grinding of the mammoth jaws they wont germinate easily... sacrifying the tough seedcoat substitutes this process.
This tree has the biggest leaf in our continent besides the palms. The whole bipinnate leaves can reach 39 inches long, functioning more like leaves and twigs for the plant. As a result, the true branches are sparse and stubby, giving a coarse appearance in winter. In late spring, however, the tree is converted to a lovely ferny appearance. These leaves are among the very last to emerge, thus avoiding late frosts and allowing plants to thrive under them- it casts light shade. It has nice summer foliage, a clear yellow fall color, and the leaflet stalks may turn red after the leaflets fall, providing a 2-stage color effect. But that also means repeated raking. This tree strangely completely free of insects and diseases, with very few organisms willing to take a nibble. This tree is tough, being bothered little by heat, cold, road salt, insects/diseases, and drought. The seeds are poisonous but are not east to get- male and females are separate and must be grown in close proximity to get seeds. These seeds have good germination rates. In the spring, sacrify the thick seedcoat and soak for 24 hours until the seed swells, and plant.
I can send only 2 seeds (POSSIBLY MORE) per person of this Ice Age relic because the only female tree I can find is 3 hours away, so I would have to go back only when I need to go there, so you might not get them for awhile. I expect to be there at least once between this winter and spring so should have some by then. This tree is a superior species in regards to planting in urban and suburban locations and merits planting.
