I love growing beans! In my garden, I grow primarily pole beans, while my mother-in-law grows runner beans. My preference is a result of my childhood veggie garden where tender snap beans occupied at least half of the plot. For my mother-in-law, runner beans are a nod to her own youth in the mountains of Lebanon where the meaty pods were slow simmered into flavourful dishes.
This bias on growing beans isn’t limited to my mother-in-law and I. In fact, North American gardeners have generally not embraced runners as a garden veggie, but rather grow them as ornamental plants. Take a peek at any North American seed catalogue, and you’ll see two, perhaps three varieties of runners offered, typically listed in the annual flower section of the catalogue. Alternatively, in the UK where runners are a popular crop, most seed catalogues will list at least dozen varieties, detailing the edible characteristics of each.
Why the bean bias on this side of the pond? After all, both types are climbers (ok, there are a few dwarf runners, but the vast majority are vining plants) and both produce tasty pods which can be picked young for snap beans or left to mature on the plants for a harvest of dried beans. When eating beans, specifically dried common beans, remember the word phytohaemagglutinin. It’s a mouthful, but is important to know as it’s a natural toxin found within undercooked beans and can cause mild to serious illness. It can easily be avoided, however, by properly soaking and cooking dried beans before you eat them
Growing beans – pole versus runner:
Pole beans (Phaseolus vulgaris)
- Pole beans are a member of the common bean family and are warm season crops that are planted after the risk of frost has passed in spring. Pre-heating the soil with a piece of black plastic (like a garbage bag) will boost germination.
- Most varieties grow to a height of 6 to 10 feet.
- Pole bean flowers are self-pollinating and flower set is high.
- Bean colour can vary from green to yellow to purple, with a few varieties, like ‘Rattlesnake’ bearing two-toned pods.
Top pole-bean picks
- ‘Fortex‘: Hands down, my favourite pole bean. Why? It’s heavy bearing, has great flavour and the beans remain super tender, even if picked when 11 inches in length!
- ‘French Gold’: A yellow podded pole bean isn’t easy to find, especially one with such slender, fine flavoured beans. The vines are productive and early to crop, with the initial harvest beginning about two months from seeding.
- ‘Purple Podded Pole‘: The perfect bean for a children’s garden. The vines are long – mine often grow 10+ feet in length – and smothered in clusters of lilac-purple blooms, followed by the tasty jewel-toned beans.

Runner beans (Phaseolus coccineus)
- Runner beans are popular with northern gardeners for their ability to crop in cool, foggy, cloudy or wet summers. (Hello, Nova Scotia!) They can also tolerate light shading.
- Early runner varieties were primarily red flowered, but today the range includes white, pink, salmon or even bi-colours. The flowers are both larger and showier than those of pole beans.
- Runner bean flowers are perfect, which means they are self-pollinating, but they need to be ‘tripped’ by an insect in order for pollination to occur. Many breeding programs are working towards varieties with improved self-fertilizing characteristics.
- Runner beans twine around their supports in a clockwise direction. Pole beans twine in a counter-clockwise direction. This is important to note if you are ‘helping’ the young vines find their poles.
Top runner-bean picks:
- ‘Painted Lady‘: An heirloom variety grown for its flashy bi-coloured blooms. The scarlet and white flowers are followed by large flattened pods that are best picked when 4 to 5 inches in length.
- ‘Scarlet Runner‘: The classic and widely available variety with bright scarlet-red flowers. Did you know that those showy blooms are edible? Enjoy their mild bean-y flavour in salads or as a garnish.
- ‘Hestia: This super compact variety was bred for container gardens, growing just 16 to 18 inches tall. The bean crop is respectable, but you’ll also enjoy the pre-harvest show of pretty two-toned blooms.
Fun fact: If you enjoy growing beans and keeping a close eye on your garden, have fun observing your pole and runner beans. With germination, the cotyledons of common garden beans emerge from the soil. Runner beans, on the other hand, have hypogeal germination, which means that their cotyledons stay tucked beneath the soil. The true leaves will be the first part of the plant to emerge.

Such interesting bean bits! I have to say I didn’t realize the differences between pole beans and runner beans. I have grown quite a number of pole bean varieties over the years dating back to the old Kentucky Wonder and Blue Lake pole.Our favorite in the last few years is a Romano type pole bean called ‘Helda’. It was delisted from our usual source, but we have discovered it can be grown perfectly well from Open Pollinated seed we save ourselves. I even went so far as to write a little blog entry extolling this bean!
Niki Jabbour says
I haven’t grown Helda yet, but have it on my list for this year Sharon.. I see a few heirloom seed companies still offer it. I also enjoy the pole bean ‘Lazy Housewife’, which came from Owen Bridge’s local company, Annapolis Seeds.. it’s a great heirloom and very prolific.. Thanks for sharing!

It’s bush beans for me! But after watching so many Brit garden shows in the winter, I’d like to give runner beans a whirl!
Jessica Walliser says
Let us know how they work out for you, Sue!

Hey Sue.. I used to grow all bush beans, but now grow pole as it really bumps up the harvest. For bush beans, ‘Maxibel’ is top notch – slender green pods that are so tender they melt in your mouth. As for runners, they also make great ornamental vines. In fact, my mother-in-law uses them to create a living privacy screen around her outside patio each summer. Looks fabulous! Niki
Let us know how they work out for you Sue!

I would never abandon the classic yellow wax bush bean, which always seems to be the first to bear fruit. I can rely on my beans!

I plant boring old blue lake pole beans every year. They are very reliable though and hardly any strings, good for salt pickling.
Supposedly, Runners (Phas Cocc.) originated in high regions in Mexico. They tend not to produce well in hot climates. That was true this spring in PA where it got hot early..in the late summer, however, conditions were right and we had an abundant harvest from the same vines in late August and September. The main bee species working the flowers appear to be carpenter bees..not sure why this wd be..but I’m grateful! I’ve saved some seeds for next year but plan to dig up the roots and replant them next spring when they are likely to get started quicker and maybe produce before it gets hot. The vines are about 12 feet tall so it is a challenge to pick ’em.

I grew up eating and growing runner beans which always provided a huge crop and I didn’t even know of pole beans until I came to the States. Although I quite like pole beans, I find that they are much skinnier than Runners and do not have so much flavor. What did amaze me was finding that Runners are frequently grown as decorative plants and to attract hummingbirds. What a waste!
With the superior flavor of the Runners they will always be my choice.
My grandma always grew runner beans and was disappointed in other types. My dad tried them one year bc she had talked so highly of them and was so disappointed. Its a funny story bc he didn’t know anything about growing beans, he had always mainly grown tomatoes and peppers. So he planted the runners in a flat garden bed next to the tomatoes in mid may. By August they were tightly wrapping around the tomato plants and hadn’t produced any beans so he pulled them out. Years later he recounted this to me and I told him he’d pulled them out just before they would’ve really started producing and that they need a trellis to climb. His eyes got huge and he simply said “you’re kidding me!”
