My understanding is the same - genetic analysis revealed it to be a butternut/heartnut hybrid... even though it's been propagated as a 'butternut' for many decades. NNGA annual proceedings, some years back had an article by Dr. Charles Spurgeon (Indianapolis, IN, IIRC) detailing resistance/susceptibility to butternut canker of various cultivars in his orchard... including, I think, Bountiful.

I have a seedling of Bountiful - pollen parent unknown - growing here, started from a seednut I brought home from a 1998 KyNGA meeting. Nut it grew from resembled a typical butternut; seedling has not yet produced nuts, but has pushed staminate blooms the last couple of years.

Butternut/Buartnut/Spurgeon/NNGA, etc.

Thanks lucky_p - sad to see from that that Mitchell is reported as suffering some from canker, was hoping to plant Bountiful with Mitchell for pollination. Do you know of any other nurseries offering Buartnut varieties? Only other one I've found is Nolin River Nut Tree Nursery, who offers Ayers which I believe is another variety of buartnut that's been misreported as butternut. Everyone else I've asked is just offering seedlings or pure butternut.

I have had one for about 10 years . Kind of disappointed in mine . It is hardy here in zone 5 . No disease . Just really poor production . At the time I purchased mine they recommended Westfield heartnut as a pollinator . It is not . They do not bloom at the same time . So poor production on the heartnut because the male and female blossoms do not open together . A few overlap . Bountiful does self but so far few blooms .

Badgersett "Survivor" tree planted 6/11 acquired canker following year; 2013 began copper screen wrap treatment of cankers; seems to be working: cankers closing, renewed vigor. Added 2nd tree from local garden center (Hanson's) and hoping for best.

I don't know... Ernie Grimo, Cliff England(England's Orchard & Nursery), Burnt Ridge Nursery ... may carry some butternuts/buartnuts - and if you contact John at NRNTN, he probably has some that are not listed in the catalog... but may or may not have them available in any given year. I know that at one time the NRNTN folks were working with TN Div. of Forestry, propagating native butternuts that looked to be expressing some evidence of resistance - though the picture was not rosy.

I've got two seedling native 'butternuts', from seednuts sent, years ago, by a GW member in north Georgia; They are now producing a few nuts, which resemble those they grew from, a more rounded egg shape than most 'butternuts' I've seen, but they are definitely at least one-half J.cinerea... I just don't know what their pollen parent might have been. Hoping that between those two and a grafted 'Late Rhodes' heartnut (the only one that survived the Easter Freeze of 2007), I'll get a few more nuts from the mix over the next few years.
