Marsol (aka Marisol) is a natural chestnut hybrid, a cross between a European chestnut (Castanea sativa) and Japanese (Castanea crenata) (CA 07).
As a rootstock, it is more vigorous than Maraval (equal to Bouche de Betizac or Comballe).
Trees are of medium height with a long trunk and branches higher up.
Early bud breaks makes the shoot development sensitive to spring frosts.
The triangular nuts are mid season ripening - shiny red mahogany in color.
