Whitecurrants turning into redcurrants
|
|
|
| I have a whitecurrant bush at the back of my garden, or at least every
year that I've watched it so far it has produced whitecurrants.
However this year everything on it is ripening now and turning into
redcurrants!
Is this normal? Has it just never ripened properly in the past? Do
they 'revert to type' after a while?

My immediate thought is that you have pruned rather hard, and removed
the grafted variety in favour of the root stock.
Mark you, I have no idea if whitecurrants are sold grafted onto a root
stock, so you are free to ignore me if you choose.

It would appear you are not alone.

Extract.
Currant (Ribes rubrum).-A bush purchased as the Champagne, which is
a variety that bears blush-coloured fruit intermediate between red
and white, produced during fourteen years on separate branches and
mingled on the same branch, berries of the red, white, and champagne
kinds.11 The suspicion naturally arises that this variety may have
originated from a cross between a red and white variety, and that
the above transformation may be accounted for by reversion to both
parent-forms; but from the foregoing complex case of the gooseberry
this view is doubtful. In France, a branch of a red-currant bush,
about ten years old, produced near the summit five white berries)
and lower down, amongst the red berries,

p. 876, Mr. P. Mackenzie states that the bush still continues to bear
the three kinds of fruit, "although they have not been every year alike."
