We have one of those wooden fences enclosing our back yard that are called Shadowbox Fences. They are designed to be esthetically pleasing to both the interior view and exterior. I guess you would call it a neighbor friendly fence. Though it is for privacy, we have a pool in our back yard and have it mainly as a safety feature to keep any small curious children from wandering into it without an adult. (Our brilliant fence installer put the locks at adult height so no little fingers can reach them). We live on a corner lot and our yard has a ton of "street visibility", so we plant our green beans on the outside (street side) of the side fence. (The inside of the same fence has okra, which would be highly visible from the street) To our neighbors it just looks like we have a cool vine with small flowers climbing the fence, directly behind the knock out roses. To us it looks like a steady supply of fresh green beans throughout the summer. Well usually! This is what our current crop of green beans looks like!
As you can see our green beans are purple. I did a little research and it seems if the soil is particularly acidic sometimes the green beans will turn purple. I know we have an acidic clay soil. It is one of the reasons our azaleas are such prolific and beautiful bloomers, but this has never happened before.
After about 2 minutes in hot water or steam they are nice and green again, but it was a little disconcerting the first time we picked them and cooked them. The taste? Exactly like any green bean you have ever eaten.
So hopefully we will continue to eat purple beans through the middle of September before we have to pull up the vines. I do think for next year we probably need to change planting locations plus we need to do some heavy soil amendments to that area. Hope you are all having luck with whatever you planted and your food is the right color!
p.s. Next year there will be no strawberries planted here, unless I do them in hanging baskets. They bloom, they grow and they feed the chipmunks. I have not gotten one of them because they are eaten before they are ripe. All I have is well fed chipmunks!
