We bought a packet of bean seeds about 6 years ago from M10. Unfortunately we lost the packet and can't identify the name of the bean. Can anyone help. The seed is black when you plant it. The beans are a climbing bean. Very flat and Matt (not shiny). They are the BEST tasting bean and produce prolifically. We save the seed annually, but would love to know what they are. Please!

Hi www.koanga.org.nz have a black runner bean seed called Takamatua. Check the photo on their site. Great range of NZ heritage seeds on this site.

Go to a seed selling website and look through the beans seeds they sell, you will probably find what you grew. Try Boondie Seeds or Eden Seeds.

It does say sub-tropical Geraldton to Carnarvon. Being 65 klm south wouldn't make any difference.

Is it too late to sow runner beans in glass house

I have never had a glass house, but if I did and lived in a cool place, then I think the glass house would raise the temperature a lot inside to maybe temperate or even sub tropical levels. Apply that thinking to your planting and growing times.

Hi, I planted seeds in December, but although the plant continues to grow, to date, I have not had any flowers? I have previously grown them in the same vicinity very successfully. Any ideas will be gratefully accepted. Thanks

If the soil is very rich they would probably produce a lot of growth before flowering. I had climbing beans in a new rich garden bed and they grew to about 1.2-1.5m before flowering. Plants would have gone to 3m if the trellis went that high.

Short pods on healthy plants could be caused by poor pollination due to heat. Beans are a warm season crop but pollination and bean set on climbers like Scarlet Runner can be reduced on very hot days. I have seen Scarlet Runner with some good pods then a gap on the flower spike where the beans didn't set pods then more pods. Beans are self pollinating and don't set on very hot days. I presume the plants are growing from a root that has been in the ground for a number of seasons. As you suggest, regularly picking is a must to stop beans going tough. Cutting back the tops of the runners will reduce your harvest in the short term but will encourage denser growth and may make the plants more manageable. I trust this helps. Maybe another reader has some ideas to solve your problem.
