This year I grew cosmos plants for the first time (from seed that too).. and they’ve now grown to a height of about 2 metres!! Lovely pink flowers held up on thin stalks. The height of these flowers means that they’ve opened themselves up to being photographed from underneath against the backdrop of the blue sky (as below).
