Eryngium alpinum ‘Blue Star’ 藍刺芹
Last year I have grown some plants from seeds. This winter I am going to grow some more. It is slow growing perennial. I like its special look! It blooms in summer.
Plant info see this useful website:
Clematis alpina seed collecting採收高山鐵線蓮種子
This is the look when it flowered this May.
And these are the seeds…they remind me the images of sperm shown in biology class…
