During my short walk I've noticed this meadow. The temperature drops below zero quite often now, but those flowers are not going to die so easily.
The meadow consists of flowers called Raphanus raphanistrum, mainly. I've made another picture of it:
It's an edible flower which originated in Eurasia, but it can also be found in other areas of the world. Stems and leaves are used to make salads, and its roots can be boiled after you peel them.
