There's nothing wrong with them, that's how they are inside. Have a look at the last two photos I have uploaded - woodland/alpine strawberries on the plant and on the plate. Have just taste-tested them and they are deliciously ready to eat. I have them every morning on my cornflakes :-)

Not sure, never grown them, but I do know that alpine strawberries come in both red and white, so as long as yours are tasty, I wouldn't worry about it.

As has already been said there is nothing wrong... tiny little explosions of sweetness. Beat the heck out of any cultivated strawberry any day of the week!
