I grew this variety of french climbers for the first time. They taste good -
fresh or frozen.
Strangely, half the plants have produced flat beans with a wavy edge. The
remainder are the rounded type.
The seed packet is Fothergills', generic style with no pics. Is this usual
for B.Lake? TIA

No - Blue Lake are rounded (and, as you say, lovely flavour). Sounds
like the seed got mixed in packing.
