I visited Altamont gardens about 8 years ago with mum and brought home this Californian tree poppy, Romneya coulteri, from the excellent garden centre there, Altamont plants. It was a tiny slip of a thing then. It is now 7 foot tall and covered in flowers, I was so happy when I saw the bees collecting pollen from it.
Truly, all the flowers of tomorrow are the seeds of today and yesterday.
Their sacs look packed, it is such a vibrant colour too.
