Hello,

Is there a difference between a primrose and polyanthus? I ask because
the Thompson & Morgan catalogue has arrived in the post and it lists
both, yet they look the same.

Thanks,
Stephen.

Polyanthus are hybrids between cowslips and primroses. I suspect that
morphological boundaries are fuzzy, but to a first approximation
polyanthus have multiple flowers on a stem, and primroses just one
flower per stem.
