Extending flowering periods

This wonderful plant of Dendrobium aphyllum has just started flowering in the roof of our cool Americas section (min 12C) where it has spent the winter. It is interesting to note that the plants of Dendrobium aphyllum that we moved back to their Warm Asia Section home (min 17) in February flowered back on April 5th (photo below) showing that flowering can be controlled by a month or so with lower or higher temperatures. This is useful for shows but is also reflected in the wild where we have seed Dendrobium aphyllum in Sikkim at Easter – in full flower at 300m altitude and in tight bud at 600m altitude.

The photo below shows the species in situ in Sikkim
