I love to grow Oregano for the bees and butterflies and on a warm sunny day, instead of tearing around the garden, time to pause to watch the butterflies. Today I captured a Peacock butterfly flitting amongst the flower heads assiduously extracting nectar and basking in the sun.
Oregano and its close relation Marjoram are very easy to grow, too easy. Oregano is a great self seeded and will pop up everywhere. It can also be a bit floppy and really needs support otherwise it can sprawl sideways leaving a bald mid plant. Easy to grow in a good sunny area Oregano is attractive, the variety in the image is Origanum onites common name Pot Marjoram with lovely mauve flowers. There is also a popular golden leaved variety called Origanum vulgare 'Aureum' which has the RHS merit award so always a good choice.
Why not create a butterfly paradise and plant a Buddleja, with Oregano and Sedum, around a garden seat so you can sit and enjoy the butterflies. More ideas for plants which attractive bees and butteflies.
