I bought a Polish Spirit. The only difference I noted between a
Jackmanii and the Polish Spirit is that the Jackmanii photos always
seemed to have four petals and PS had five. I've read that J. can have
4-6. I also understand the PS is clasified as a J.

The clematis I have has over 15 flowers but all have four petals.
Is the number of petals 4 vs 5 vs 6 controlled by variety or
environmental/fertilizer. I actually prefer the fuller look of a five
or six petalled one.

Sooo... is there a variety that tends to have more petals. Is if just
a random thing? More petals when the plant is well established?
