Agave Salmiana in Flower

In my garden,at the southern edge of London, I have an agave salmiana planted out since 1992. It has now grown to immense proportions and a week or so ago
(20th September) showed the first sign of flowering. 
In habitat the flower stalk of salmiana can reach 8 metres, what will happen in Worcester Park we''ll have to wait and see.
