Manna Oak is the first selection of oak that has no detectable trace of tannin or bitterness when eaten fresh off the tree even in the green stage. The green stage of acorn development is the highest point of tannin found in an acorn as it prevents predation. Even squirrels rarely eat green acorns.  Manna has none and leaves no trace of astringency or dryness on your tongue. The acorns are not bitter and can be eaten without leaching. 

This rare find was created by oak breeder Miguel Marquez as he provided us with acorns of crosses he did using the original "Ashworth" but oak. The tree did self pollinate and produced a viable acorn. That viable acorn we planted at our farm about 25 years ago where now it has been producing for the last decade. 

Manna is a good producer of 1 inch sized acorns that cluster near the ends of the branches. . To find an acorn with no discernable bitterness is extemely rare. For this reason, it is worthwhile growing from seed this unique find to create similar seedlings as the parent trees surrounding Manna are also low tannin Ashworth seedlings.  Scionwood will be available in the winter of 2022 as this unique find is very rare. 

Plant Specs
Genus & Species Quercus macrocarpa Ashworth x hybrid
Seed Source Michigan
Hardiness -25F
Height (ft) 30-50
Width (ft) 30-50
Pollination Requirements Likely self fertile to some extent. Wind pollinated. May benefit from other bur oaks or have two plants to insure good nut set.
Climate Zone 3-8
Ease of Cultivation One of the most adaptable oaks to grow in a variety of soils and climates. Practical in terms of its use for flour as it requires much less work to leach. This selection is useful as a precursor to developing more nut oak selections because of its insanely low tannin levels. We hope to have it tested in a more objective approach, other than human taste buds.
