Flowers, spikes and salad
This plant has a very interesting way of spreading its seeds. The plant has big, spiky leaves and a very spiky inflorescence. When the seeds are ready, the whole plant dries out from bottom to top and gets a spherical shape. Then, the stem is separated from the ground and the whole plant is swept away by the wind, rolling and rolling and spreading its seeds in the fields, with the big dry leaves catching the wind and moving the plant around.
The plant is edible when it's young and green, especially the big, juicy stem. In fact, it is so good that it is considered a delicacy amongst the Arab population in Israel, and almost got extinct! Today it is a protected plant and you can find it again growing in the open fields.
Also, some people believe that this plant was used to make the thorny crown of Jesus from Nazareth. For more info, take a look at that:
Well, I don't know about that, but what I do know is that it's a beautiful flower indeed :-)
