I just moved into a house in Rhode Island that has periwinkle in the flower beds. I am not familiar with periwinkle and am wondering if it is safe to plant my tulips dahlias and other flowers in with it. Does periwinkle choke out other flowers?
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.
I planted cuttings last fall in an area that had only weeds and grass before. Now I’m wanting to know what it looks like just popping out as opposed to weeds, etc.
You should be able to identify the bright waxy looking leaves. That is how I would describe it.
This link shows an image of seedlings.
How do I control the weeds around the periwinkle without harming the periwinkle itself? I have a lot of sun in some areas. When I plant new periwinkle plants, it doesn’t take-off and expand.
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.
