Which is a sweet cherry?

hallo,

i want a cherry tree in the garden - has to be black fruited, self-fertile and as sweet as honey. these are the varieties i have come up with sofar: sweetheart / sunburst / merchant / kordia --- i dont have space for more than one tree.
QUESTION: does anyone know which one is the sweetest variety?
thanks, karaman

 

Sweetheart as its more of an eating variety not sure of the others

 

Must admit I'm not well up on cherry varieties, they grow a lot around here and are avilible from july to mid august most years from local orchards.
So, I'd never bother growing one myself , bearing in mind bird problems and splitting in wet seasons.
I was under the impression that it was mostly the morello cherry that was considered sour.
Just for a bit more input, a local nursery that is good.

Most cherries need a pollinator so best check that before you plant only one.

 

Suggest you contact a reliable grower who can advise you on size of trees, time of fruit, flavour and pollination.

On the Deacons website they show 6 dessert (sweet) ones and claim all are self-fertile.

I have not bought cherry trees from them, but they were excellent for apple trees. They say Lapins is resistant to splitting.

 

magic! lots to think about, thanks to all -- tending towards a sunburst fan but have to sleep on it...

thanks again to everyone, its so good to get lots of opinions. cheers, karaman
