The flower color of standard asterias is yellow petals and orange throat. There is red flowering asterias developed by Japanese origianally. I tried to get red flowering asterias a while but it was hard to get. I started from seeds and so there was no guarantee seeds named "red flower asterias" to be red flower asterias.
I got 2 asterias almost true red flower and many unlike.
The photo is one of unlike red flower asterias. I think this one was crossed many times and the size of body is very small. The gene of thin petals is also mixed.
