What was that weird and useless cross someone once did, radish and
cabbage? I vaguely recall it results in a plant that's all bolt and no
nut (grows a seed head but w/o any useful edible parts).

I didn't hear about that one. Radish and cabbage are certainly close
enough to be crossed. Radish seed pods are very edible and I have
heard they are great in stir fry recipes. Perhaps they were trying
for bigger, better seed pods but it didn't work out.

Suppose the world worked differently than it does and you could
actually cross broccoli and lima beans. The cross wouldn't change
the appearance of either parent plant. Pollen of one would fertilize
the other and nothing would look different until the resulting seeds
were grown and the new hybrid would appear. (I just have to wonder
what that plant would look like!)
