Mystery vine!

This flamboyant vine has crept over our fence from next door - it is a plant we have seen when on holiday in Cuba, and we never discovered its name then. No-one here seems to know its name. Some years are better than others and actually there are not too many blooms this year. Probably because we have had very little rain this summer and it is certainly hotter than usual. Global warming as well as Covid-19 - ah well!!
