It took me a while to identify this plant.
We had purchased a Trumpet vine from a roadside vendor and there were many little seedlings growing in the tub. I asked the vender what they might be and she answered 'it's a surprise'... Sure was, they are now everywhere in our garden but it's a beautiful thing. They afford color wherever there is space along the back fence and we need do nothing to ensure that they are back again the following year. They reseed themselves wonderfully and I recommend them to anyone looking to fill in space in their gardens. Simply pluck out the ones you don't want. Might be an issue if you have small children and/or pets as the sap is poisonous.

We recently discovered it's name and I posted a picture of it here.
The plant is a good source of nectar for attracting butterflies, especially in the "off" season when there is not much else blooming in zo... read more
