I have one rhubarb plant which is from UK. I live in SW Romania, which is a lot warmer. The rhubarb is in flower. When and can I collect the seeds and would they grow if planted in pots placed in our small greenhouse? I would like to increase the rhubarb plants but here in Romania one cannot find this plant. Many thanks.
The recommended means of propagating rhubarb is by division – instructions on how to do so are found here:
You can try propagating by using the seeds, but I read that the seedlings rarely resemble the parent plant since most rhubarb is cross-pollinated. So you would probably end up with rhubarb of poor quality. You can read more about this at the following extension website:
