'BLACK TOPAZ': THE REMARKABLY DARK MUTATION OF 'TOPAZ'

Home  Ι  Varieties  Ι  Dessert varieties  Ι  'Black Topaz'

The quite newly discovered 'Black Topaz' is (after the already widely popular 'Red Topaz') another natural mutation of the well-known variety  'Topaz'. They all share resistance to diseases, low growing demands, and delicious taste. 'Black Topaz' will catch your attention thanks to its unusual very dark purple-red fruit skin colour.
