In may 2011 I received a flask of P. venustrum that is flowering for the first time now, after approx 1.5 years. This time I got 5 flowers on approximately 10 plants. Here they are, in 50mm(2 inch) square pots. A view from above, the plants in front are mostly charlies (album and normal) received at the same time, no blooming yet A close-up This one was two weeks ahead of the others and got the petals curled up. Perhaps not perfect, but... Some other flasklings, here malipoense deflasked in march 2012; recently potted. Amazing how they grow...To the left some recently potted micrantum var. eburneum. deflasked same day as the malipoense. Tranlienianums also deflasked March 2012. 50mm pots And so were also these vietnamense. Yummy leaves here. Astonished by their growth rate. also in 50mm pots And YES! the substrate is mainly marble(grey) mixed with dolomite grit(white) plus some sand, leca and organics (minor amounts) - the venustrums have basically a bark based mix.
