Planning ahead.

Lucky you - all that space! Roses are expensive & you'd need a lot for all that length of path, and you still have to decide what you want to cover the soil with unless you want to do a lot of weeding! A mix of herbs & lavender would look lovely along the path & things like thyme & marjoram spread very quickly & need little attention. Or how about some prairie planting? Have a look out for cheap perennials from the garden centres at the end of the season - they often sell things off quite cheaply, and they may look tired & tatty but will be fine for next year.

Again, probably not cheap for the whole way , but maybe for part of the way, I think that lavender would be very atttractive. Lavender Hidcote or Munstead maybe.

You can buy hedging lavender in large numbers relatively cheaply. Look online or in the back of gardening magazines. I like Cornishsally's idea of lavender and herbs.

ooh this is lovely, what space to work with. Love the wildflowers looks great. The answers you have been given are great. I would go with all the lavenders and herbs etc what fab aromas you would get as you walk down the path

Roses become cheaper per plant the more you buy.

Thank you so much for all your replies. The inner part of the path is planted with lavender (I should have said). Hadn't thought about herbs along the outside though, sounds like a very good idea.
Chamomile is growing between the stones so it could be a very fragrant walkway.
Thank you.

chamomile is delicious
i have this in various pots around my garden and the smell mmmm
I can never resist a quick sniff
