More Details

Runner Bean 'Polestar' is my favourite form of runner bean which is stringless – tasty and tender. Just one sowing of this will give you plenty of beans for weeks at a stretch, or do two – one early, one late – for picking summer and autumn. Delicious flowers too.

These are perfect planted on a teepee with your favourite scented sweet pea mix – as this will attract beneficial pollinators.

Autumn in the Vegetable Garden

It's a fantastic time of year in the kitchen garden and down at the allotment.

Allotment Open Day

Perhaps a little bit nosy but there's something really exciting about checking out other people's plots, marvelling at their runner beans twining up...

I was particularly pleased that these survived and flourished well into autumn. They were sent out rather early and despite careful handling reached a height that meant they had to be planted out before I would have wanted to. A later despatch date would have made the season less nerve-racking!

The runner beans grew extremely well despite the drought and cropped really heavily. We had more than we could eat and plenty to give away. Picked on the young side, they were also a very tender, tasty variety with almost no strings to remove.

As a completely new vegetable grower and allotment holder, these were the beans that I picked out at Sarah Raven seeds to grow. I watched Monty Don plant his bean seeds and I did exactly the same, planting two seeds next to the bamboo wigwam. Within a few weeks they came up. I've been picking ever since. So easy to grow, no disease, just delightful tasting beans. I haven't tried eating the flowers but I believe they are also edible too. Perhaps beginner's luck, but I am very pleased with this variety which is tender when cooked. I like to cook mine for a few minutes in water with a garlic clove. I am definitely buying this particular bean again because they are easy to grow and delicious to eat. I did find if you leave the beans to grow too large, they become stringy, but I prefer them around 10cm long, when they are still tender.

Super runner beans
