Strange blue flower, weed or not

Please see the attached photos of a flower that has suddenly appeared. Despite many years of gardening I have never come across such a plant.

Hi @patytoo

Thats a Salsify plant (Tragopogon porrifolius). Considered a root vegetable that's quite rare! The root has an Oyster flavour and it produces a long slender flower like this. Salsify is also known as Oyster root, purple goats beard or vegetable oyster. A bit like a parsnip in texture but wth a oyster like taste.

It's a biennial plant, so grows its root first then flowers in the second year before being ready to harvest. The flowers like you have experienced open and close in sunlight known as diurnal movement. Salsify like free draining and light soil not clay. Once the flower of Salsify finishes its left with a dandelion-like seed head.

Salsify can be harvested from late September. Ease them out of the ground with a fork gently. Cook the roots then remove the sticky skin off them before eating. 

Happy gardening!

Lee
