rhubarb plant (variety = Victoria), complete with flowers whose colours remind me of rhubarb and custard. We've had several delicious bowls of the stuff lately, so the comparison's foremost in my mind ;)
Just after I took this photo, I cut the flower stems off at the base. Rhubarb flowers are said to weaken the plant, so I don't want to put mine at risk. However, apparently the seeds can be ground into a flour which makes very good pancakes if you don't mind sacrificing a plant or two.
I'm not sure if flowering rhubarb means it's mature and happy or stressed. This is the third year mine has flowered and there's been plenty of discussion on the internet in previous years on why this might be. Overfeeding with nitrogen (forgot to manure mine last winter); a damp summer (last summer was dry, though the two previous ones were very damp); the plant needs dividing (it's over 5 years old so this could be true); the result of a decent cold period (which rhubarb needs to do well and we've certainly had the last three winters) have all been given as possible reasons.
No matter what the reason may be, I've found that cutting the flowers ASAP does the plant no harm and it continues to crop well. So there's lots more bowls of rhubarb and custard to come :)
