One of my Rhubarb's seems to have bolted and has a pinkish Cauliflower like head to it. is this its last gasp?
I only planted it last spring but it was moved a couple of times before it got its current final position. My other Rhubarb's look fine. This one has pale stalks mostly but the other ones have redder thicker ones but are slower growing (you can see one in the background of the picture below beside the fallen over blue lantern (used to distract cats - don't ask!!).

Should I cut out the "Cauliflower" stalk or just resign myself to losing it?

Remove it, if it is flowering it is under stress and is producing flowers to help reproduce itself, I would mulch it with well rotted FYM and water it, remember rhubarb has big leaves so water the leaves and they will funnell the water down to the rots note the large chanels in the leaves and stalk which allows water down to the roots where it is needed,

Does it have to be stressed to do this? My two have been in situ for three years now and each year they try and produce these flowers. I just snap them off when I see them and all seems to be good.

well a plant always flowers before it dies to reproduce itself so it is probably caused by stress in the plant. The flower stalks do not usually grow on younger plants, but are common on plants that are 3 or more years older. Also some varieties are more likely to flower than others. Rhubarb is not poisonous after it flowers and is ok to eat and you can still compost the leaves.
