Rhubarb produces a flowerstalk and flowers so that it can produce seed. all plants need to propagate. Rhubarb can be grown from seed, but first the seed has to be produced!

Best you google about it. Flowering is part of the life cycle of plants.

Where do you buy the rhizomes from in Western Australia Perth area? I have tried before to grow but with no success so going to try containers. Thank you. Faye

I live in south central Tennessee and want to grow rhubarb. Can I do so as a perennial or do I have to treat it as an annual? And where is the best place to plant the crowns?

Is it normal for rhubarb roots to grow on the surface. I have two roots from a 2 year old plant growing along the top of the ground. Could it be looking for more water. Thank you
