Every year I plant peony poppies with saved seed and they are amazing. So easy to grow as well as being beautiful with so many different colours.
But the absolute best thing about them is that the bumblebees go crazy for them. It's the best thing to watch in early summer by far.
If you are looking to add some easy colour to your garden next year all you do is sprinkle the seeds on top of the soil and wait for the flowers and bees to come.
