The Native Plant Store can Now be Found Here

  • This page will remain accessible as a library page until I have all the species moved to the new page and all the quirks worked out in the new software so it can function as a searchable library.
  • Please see the Using the Plant Library  page  for some tips on how to make the most of the information in this existing library to select species for creating a healthy native plant community suited to the conditions of your site.

Strophostyles helvola, Trailing Wild Bean

Strophostyles helvola 

Trailing Wild Bean

  • Annual vine
  • Average to moderately wet or moderately dry soils 
  • Full sun 
  • 8’ Tall, Vine -Requires something to twine on
  • Mid to Late Summer blooms
  • Ontario native, Beginner Friendly, Annual thrives in Meadow, Sand Dune and Open Woodland ecosystems

A finer, more visually delicate version of a pole bean, these are vigorous twiners that could likely exceed 8’ in height in a growing season. Their delicate flowers begin to appear in mid summer, when they open pink and age to pale yellow, before fading away as the narrow pod of small beans develops. Reportedly edible as both as a green bean (pod) and at the mature stage (boiled or roasted seeds) these are also a host species for nitrogen fixing bacteria.

I planted them in a pot and provided a branch for them to climb on. They happily scrambled up, eventually twining themselves into the fake shutters on the south facing brick wall at the front of my house. They coexisted well with the Pennsylvania Smartweed that shared their pot and they attracted both pollinators, with their flowers, and predatory wasps with their extrafloral nectaries. If I had left the seed pods, rather than gathering the seeds this year, they would likely have been consumed by one species or another of critter as the fall and winter progressed.  

Trailing Wild Bean are a lovely, adaptable, native, annual species that I think would fit well into a lot of native and vegetable gardens, including ones in containers.

While it rarely comes up, I do reserve the right to limit plant quantities, mostly to help ensure that as many native plant gardens as possible become a reality
