    It will work well with all of those plants. Periwinkle is a great plant for working with others.

    With the weeds other than wild onion, you can use a broad leaf and grass specific weed killer. But, wild onions are notoriously resistant to herbicides. The best method for getting rid of them is to dig up the clumps.

    There are many varieties of periwinkle. They are a beautiful rounded blue flower that resembles the daisy - some are full with double petals (which look like a double daisey) and others are five petal flowers. There are some good pictures on google. They are often used at weddings. Hope this helps.

    You should be able to identify the bright waxy looking leaves. That is how I would describe it.

    You have a few different options: you can hand pull the weeds out of the ground by the roots, lay mulch around the periwinkle to discourage weeds, paint the foliage of weed plants with a glyphosate herbicide or apply a pre-emergent herbicide to the periwinkle bed.

    For more information on periwinkle and pre-emergent herbicides, please visit the following links:

    It's a type of Periwinkle I believe.

    Madagascar Periwinkle fits the leaf and flower pattern.
