Gosh, where to start? Have been growing these since 2002 in a 5a and at elevation - well outside their native range. 80% become sprawling bushes with suckering. 20% have grown into small trees topping out at 12'. they may grow taller in more ideal zones but this is a 5a zone with LATE frosts and a short growing season.

Very susceptible to phytophthora root rot. Prefer well-drained, rocky/sandy slopes, acidic soil. Hard to propagate from nuts if you live in a cold winter zone due to vernalization requirements. Does not compete well. Only moderately self pollinating.

Outstanding wildlife value. The best tasting nut I have ever eaten in my life. Will produce catkins in 2nd or 3rd leaf. Heavy production by year 5. It may be the most undervalued mast bush... read more

Native to east Texas up to south Missouri over to northern Florida then north up the Atlantic Coast and Alleghany Mountains into southern Pennsylvania and parts of New Jersey. Grows in average to dry, acid soils that are not heavy clay. It grows successfully up to about pH of 6.8 and maybe to 7.0. A medium to large shrub that can become a small tree somewhere very favorable. It often ground suckers to form a colony. It is a very interesting native plant with pretty foliage that bears sweet, edible nuts for humankind and many animals in September and October. It can sometimes suffer from too many weevils and it has various levels of susceptibility to the Chestnut Blight Disease of a little to a lot. If hit hard by the disease, it grows back from the ground suckers. It is sold by some native... read more

A small native tree found on dryer soils which is quite
valuable for wildlife. It is sometimes damaged by Chestnut
blight but much less so than Castanea dentata.
