Earlier this year I posted about using a combination of cardboard and newspaper to turn some lawn into garden bed (see photo at bottom). This spring I dug holes just large enough to put in some tomato and pepper plants (the newspaper showing through is because it takes much longer for the cardboard and newspaper to biodegrade in the dry climates we have where I live in Colorado and other parts of the West). The pepperoncini pepper plant above demonstrates the success of this technique–it is growing strong, healthy and beginning to produce some nice peppers.
Pepperoncini peppers are those 2-4 inch light green peppers sometimes found on salad bars and also included as garnishments with sub sandwiches. Though often pickled they are also eaten raw. They are mildly hot while green though can turn hotter if left on the vine when they turn red in color. They are a good source of vitamin C and quite tasty.
My pepperoncini pepper plant is very productive as can be seen in the photo above. Lots of blossoms that are turning into little peppers (some of the small peppers still have part of the blossom from which they started still on the end of the pepper) with the help of the wonderful bee pollinators I welcome to my yard (I plant sunflowers near my vegetable plants to encourage bees to come pollinate them).
