'TOPAZ': THE PROVEN CLASSIC OF ORGANIC ORCHARDS

Home  Ι  Varieties  Ι  Dessert varieties  Ι  'Topaz'

Easy to grow and with a very good taste - an apple variety that has proved its qualities and deservedly become popular among European professional and amateur growers alike. Together with its mutation 'Red Topaz', 'Topaz' has become one of the most cultivated apple varieties with genetic scab resistance grown in organic conditions - and it is a good fit for home gardens, too.
