Lots of plum(ing) questions

[wildherbalian85]

Ok where shall i start........

i am photographing all the kinds of plums that happen to be growing wild around my area though some may look the same they do have distinct differences in taste and also other difference's such as the tree's leaf shapes.

Anyway i have a few questions...

1. This plum when fully ripe is a very tasty plummy plum but i think it might be a damson of some kind, at the moment they are not ripe and have a very sour taste not too dissimilar to that of the sloe berry. What is it??






2. Why where all the plums from 1 perticular tree pear shaped???




3. Is this some kind of disease that i found growing on these two individual tree's, as you can see with mirrebelle it is far more widspread and all of the leafs where like this....



and on the other tree you can also see it a little......

This could be a fungal parasite - you could put a photo on the Fungal Plant Parasites thread. Chris Yeates is very good with these types of things.

KT17....

looking at these leafs i think it might be possible that this is a Red Spider Mite infestation.... after looking at other diseases that effect these kinds of tree it would seem all have an effect on the fruit yet the fruit on my tree's is good: healthy and plentiful.

What do you think?

The first one is a form of Prunus domestica ssp. insititia - probably a damson (var. damascena)
The second I don't recognize but is a form of Prunus domestica ssp. domestica (i.e. a Plum)
The last two both look like Cherry-plums (Prunus cerasifera) to me. Mirabelles (Prunus domestica ssp. insititia var. syriaca) have a much smaller rounder fruit

Thank you So it is just a damson... nice

The second was growing in amongst lots of Prunus domestica var cerasifera (as you call them), you can see the dark cherry coloured small plums next to the pear shaped plums. I think its it a cherry plum tree that might be growing mutant fruits It certainly didn't taste like a mirabelle.

The yellow in the last two where larger then the red and where typically 2cm -3.5cm... the red where typically around 2cm - 2.5.

Mirabelles are not a small (relatively speaking) fruit.

p.s. i know for certain that the yellow fruit pictured in the last photo is a mirabelles.. it comes from a tree purchased several years ago.

There seems to be a lot of confusion in the naming of these two plants. Two cultivars of Cherry-plum ('Golden Sphere' and 'Gypsy') often are referred to by the name Mirabelle. Just because you bought the tree as a mirabelle doesn't necessarily mean it is one.
