Does anyone know this Campanula?

We attended our local Ramsbottom Horticultural Show yesterday and this wonderful Campanula caught my eye. It is named as C. persicifolia Milky Way. What fascinated me was it is like a hose in hose not a regular double.

In Peter  Lewis and Margaret Lynch's 'Campanulas a Gardeners Guide they list several double forms many of which they think are out of cultivation and go back many years, but this is not on their list.

The flower form is more like C. betulifolia.

Does anyone know it, have it and could spare a bit?

Listed  as  C.punctata Milky Way and C. persicifolia Milky Way by various suppliers from T&M to Hillview and Hayloft.

Thanks Eric. So which is it punctata or persicicfolia?

[Maggi Young]

RHS seems  only to refer to Campanula punctata  Milky  Way, albeit as a  "tentatively  accepted  name"  -  so I'd  guess that.

Thompson and Morgan want £14 for it so I think I'll pass.

Smart move, Shelagh,
C.punctata can be a bit of a thug!
cheers

That's an understatement, it's one step below rapunculoides, a tiny plant managed to cover a square meter in one year... C. takesimana is slightly better behaved, but both are probably best kept in pots.
