I have a Paph In-Charm White x niveium that bloomed fine last year. This year the flower looks good but the flower stem doesn't seem to be strong enough to hold up the flower. The other day while in the greenhouse I noticed this flower on a long stem but the flower was down near the pot. I initially thought that the stem had just grown that way and was stiff. Thinking maybe another plant stopped the spike from growing straight. Wrong! The stem just isn't strong enough to hold up the moderate size flower. Shall we say it's flaccid. Any ideas?
