One day last week, I dropped in at a local botanical shop and found pipeworts (Eriocaulon parvum) in a big case filled with rain water. They were thriving like weeds in the case but not on sale. So the shop owner willingly let me pull some of them.
Bringing them home, I placed them in a pot. Hopefully I'll obtain lots of the seeds.
This pipeworts brooming a lot of small flowers in metallic grey.
The flower looks like a very tiny artichoke.
Then I dismantled one of the flowers. There are pale white seeds between petals.
