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

My guess is that they were grown too close to a variety like Barlotta,
the originals are homozygous, and the blue colour and flat shape are
independent, dominant alleles.

If that is the case, growing seeds from the odd beans would produce
a mixture of round blue beans, flat blue beans, round green beans
and flat green beans.
