Hi Betty! Some flowers
of the corkscrew vine don't give seeds
while other times it will give you many seeds
,, As luck will have it I guess,
WHen it starts to dry up and brown look for them then ,, To start the seeds
in early spring
, Nick the ends( I use a nail clipper on hard shelled seeds
) and soak in hot water for 24 hours in a ziplock bag water will slow cool down, and them plant in full sun,, OTher wise if you don't get any seeds
( the more mature it is the better the chance for good vaiable seeds
).. propragate semisoft wood cutting by rooting in water.
Good Luck Betty!
