I haven't tried to grow a catalpa from seed. However, the way that catalpa seedlings grow abundantly near mature trees I have observed--both in eastern and western Massachusetts--suggest they grow easily. My theory is that snow plowing has a lot to do with getting the beans buried and off to the sides of roads or parking lots, where they manage to grow without interference from lawn mowers or other controlled landscaping.
Bignonia Catalpa
Angiosperms are seed producing plants. Beans are seeds.
Catalpa - The Indian Bean Tree
Yes they can. You can use rockwool cubes or a mixture of perlite/vermiculite to start bean seeds off.
No, a runner bean is a legume vegetable. It is a type of bean that is grown for its edible seeds contained within the pod.
Yes, when a bean plant produces seeds in long pods, it is a form of reproduction known as sexual reproduction. Pollination of flowers leads to the development of seeds within the pods, which can then be dispersed to grow new bean plants.
They aren't edible, but some people report that they can be used to keep moles out of your yard.
It could be a Catalpa (http://en.wikipedia.org/wiki/Catalpa).
If you sprinkle water on an open box of dry bean seeds, the seeds will start to absorb the water through a process called imbibition. This will trigger the germination process, where the seeds will begin to sprout and grow into seedlings. The water will provide the necessary hydration for the seeds to activate their enzymes and start breaking down stored nutrients for growth. It is important to continue watering the seeds regularly to support their growth into healthy plants.

Japanese Empress Tree or Paulownia tomentosa
Yes, you can plant fresh green bean seeds in your garden.
