Dunstan Hybrid Chestnut: Does it live up to the hype?

nick_b79(4/5 Southeast MN)August 28, 2010

I was looking for sources of hybrid chestnuts for my edible landscaping project, and ran across the Dunstan hybrid strain at Chestnut Hill Farm. This quote stood out at me:

"There has not been a single reported instance of Dunstan Chestnuts dying of blight infection in over 30 years. This includes research and breeding programs as well as the many other locations where the Dunstan Chestnuts have been grown throughout the nation."

Has anyone here grown the Dunstan, or otherwise had experience with it? Thanks!

Here is a link that might be useful: Dunstan Hybrid Chestnut

Does sound a bit hyped up sales talk there.

One point to bear in mind; chestnuts are outcrossing, so if you plant all of just one cultivar you won't get much successful pollination. A mix of several different cultivars will give far better crops.

===>>>> that isnt even the life span of a single tree/generation .... thats right up there with defining weather cycles on a multi-billion year old rock based on 100 years of data ...

that, and.. most trees dont become affected with problems until they are OLD .... and 30 year old trees can barely be considered old ....

Dunstan is said to do poorly in northern states. One option is to try Oikos tree crops hybrids they have, or for the best chance of growing your own chestnuts, look up Badgersett hybrid chestnuts.

Thanks for the input. I do have several Oikos hybrid chestnut seedings already (several each of their Timburr, American Hybrid, and Seguin strains) grown from seed they were selling last fall. I also have been considering purchasing some from Badgersett since they are locally grown for me. Guess I'll stick with those choices then.

Dunstans from Chestnut Hill are seed grown to my knowledge. I have about two dozen seedlings right now in containers from seed collected in Georgia (I can't legally call them 'Dunstan').

I also have the ECOS and the Timburr trees from Oikos and the Dunstans are different. The Oikos trees have less pubescent leaves and I believe they have more American DNA compared to the Dunstan.

I was given 5 Dunstan seedlings, about 2 foot size, in about 2002, purchased from the original Florida source as a gift. I planted them on a small sunny parcel on Long Island, NY. They exhibit a wide range of success versus chestnut blight, but all are infected. A complication is that the smaller ones have been damaged by rabbit and deer browsing. All 5 are alive, but three have almost completely died back, only to resprout. The dieback was definitely caused by blight. One of those resprouts is up to about 10 feet high on its largest trunk. The second best one is about 15 feet high and had male flowers 2 years ago but no female flowers. The standout is a rounded (not a strong central leader tree), about 20 feet tall and 25 feet wide which has produced a 40-60 nuts each of the past 3 years, pollinated by a chinese chestnut seedling and the other Dunstan. It has cankers but responds vigorously to them
