Flower longevity in 'Ulla Silkens'

I grow three different clones of Cypripedium ‘Ulla Silkens’. They are all healthy, robust, vigorous and multi-stemmed plants, and most produce two flowers per stem. I grow them in large plastic pots for convenience and for pest control – I have a serious mollusc problem.

My reason for entering the forum is to share and enquire with other growers the phenomenon of flower longevity. The flowers on each of my plants last no more than three days, sometimes less (in hot weather). They start to decay, with brown patches on the lebellum (pouch) which very quickly spreads to the whole flower, thus rendering them very unsightly. I also grow several different clones of their parents, C. flavum and reginae. The flowers of flavum last for at least 7 to 10 days, reginae usually longer!

I would be very interested in the experiences, comments and possible solutions of other growers.

Thank you Michael for your efforts in continuing the very interesting forum.
