It is the lovely perennial, sweet pea, that grows wild where ever the birds drop the seeds. It is a beautiful plant that can be trained to climb over fences, etc., but it will take over if not controlled.

For sure sweet pea, Has to be wild, which is not edible!

It is a Sweet Pea. Flowers smell heavenly. Do not eat this plant. The flowers and stems are poisonous. It is a highly desirable flowering plant but can be evasive. Seeds are sold at many stores and at Amazon. I love sweet peas! check it out by typing in the word sweet pea in your search bar of your browser and you will find info on this plant. It comes in many beautiful colors. Grow them on a trellis as they are climbers. Here is a link about how to grow them. http://www.almanac.com/plant/sweet-peas

It's a sweet pea.

You are so Lucky to have this perennial Sweet Pea in your garden, it may need controlling, but it's lovely, though I don't think it comes in any other colour.

The Sweet Peas that you can get in many colours, is very fragrant, but is not hardy, and only lasts for one season.

I have tried so hard to get it established in my garden, but so far, no luck.

Lucky you.
