my wife picked this growing wild in Jersey on a coastal walk, her friend swears it's a plum we have our doubts............input appreciated

John

Not a plum. It may be a type of Passiflora, possibly P. incarnata. (?)

edited reply, wrong thread!

it does look like a passiflora however the inside of the fruit is unlike any passion fruit we have ever seen.

Funny but the whole fruits don't look quite right for passiflora to me, It appears that the sepals are attached to your fruit which I've never observed on passion fruits. However, cut open the pictures are a match, including the seeds. The leaves appear to be a match for passiflora as well.

It looks like P. incarnata is just outside of your range. http://plants.usda.gov/core/pr...

Lol I think it is more than a little out of my range....we are in Jersey Channel Islands U.K.

Oh... that's for sure.! Actually that will require a whole new approach to identify your plant.

Could it be Solanum laciniatum or S. aviculare? Pictures of the fruit of both here:

Edited to add:
I will take back my guess about Passiflora.

sooby, the Solanum looks more like it; the fruit and leaves seem to match.

I too did think it resembled Passiflora but then I saw some pictures of yellow eggplant (didn't even know there was such a thing) and that led to those related Solanums. Hopefully Flatty will come back and let us know if it's a match.

Yes, Sooby! That looks more like it to me too.

Thanks Sooby this is definitely the one http://www.flora.sa.gov.au/efs... . although as a native of Australia how it got to our small 'rock' I have no idea.

Thanks for the input

You're very welcome. According to this Flora of NW Europe, it is found in the Channel Islands (and west Cornwall and south Somerset).

Presumably an escapee from cultivation. It is currently sold in southern England - the RHS lists 8 suppliers.
