Well, I suppose it would depend on your tastes in food. If you were “picky,” bless your heart, then I could see that you might find it disagreeable. Personally, I enjoy berries of all sorts, and this batch looks to be mulberry. Mulberries in a pot being transformed into a delicious dessert. Or even jam (preserves to y’all across the pond).
On the other hand, it’s difficult to get a bead on the size. Looks kind of teensy, though. American berries are BIG. (Texas berries are even bigger.) Might be some sort of Scottish berry. Are there purple berries in Scotland? Perhaps purple berries that were a deciding factor in a famous battle? Purple berries in a famous dessert?
Or, I hesitate to ask, is this HAGGIS?
I know, I should be practicing my whistle instead of getting obsessed with things like this. But a person just can’t help it sometimes. Like who is crazy me or them?
Yes, you should be practicing your whistle, and now that you know the background is just a yummy food item–even if it IS haggis–you can let this little side-issue loose to bother others. 
If these sorts of things tend to be a source of obsessive preoccupation for you, it’s important to get a grip on this right away. Before it gets out of hand. There’s a easy cure for it.
Dangle a pocket watch before your eyes, left to right, left to right. Feeling comfy? Now, repeat after me . . . “Whoa . . . whoa . . . whoa.” Just like the thing you say to get a horse to stop. “Whoa!”
Practice that a bit. Fun, isn’t it? Makes you feel warm and kind of satisfied? Relaxed? “Whoa . . . whoa . . . whoa!”
When you’re feeling really good about letting go of all that obsession–wooo! just let it all FLOAT away!–let’s refocus your energies on something else . . . simply change the letters slightly . . . to “WhOA.” Hardly a difference, but don’t you feel even more relaxed? Isn’t that better?
"WhOA . . . WhOA . . . WhOA . . . "
I recommend you spend 15 minutes several times a day with this pleasant relaxation exercise. In a week, you can come back and tell us how it’s working.
Oh, and by the way, how many whistles did you say you had?
