This is what the Turkish peppers look like before they ripen. They are a very pale shade of green.
In another pot I have "King of the North", also a Sweet Pepper.
I'm fairly sure that the fruits of this plant have been affected by the contaminated compost problem because they don't look like a normal pepper. Instead of being round and "blocky" they are thin and "pointy".
This ripening one looks more like a tomato.
This colourful fella is "Ohnivec":
I tried one of the immature (cream-coloured) ones a couple of days ago, just to see what they are like. It was surprisingly hot, but very nicely flavoured.
My "Explosive Embers" chilli plant is covered in tiny purple fruit now.
This is a very compact plant, which would be ideally suited to growing on a sunny windowsill.
Although currently a bright purple colour, those chillis will ripen to red, like these "Nosferatu" ones, which started out being almost black.
