The glasshouse at Wisley RHS

Overcast today with not much evidence of autumn colours (except for the Maples like my previous blip). In the glasshouse the seasons are negated and the flowers bloom all year round.

Sorry - I don;t know what this one is. But I did confirm that the Yucca that I blipped recently that flowered in our garden is a Yucca gloriosa variegata. They have several at RHS flowering in an identical manner.
