stars can be obtained by sowing or by collecting seeds by themselves. However, flower friends need to know that the stars are cross pollinated, and they need two unrelated star ball pollinations to produce seeds.
Indoor pot sowing is often used in spring, germination occurs 3-5 days after sowing, and flowering occurs 3-4 years after seedling grows to 5 cm in diameter.
It should be noted that the seeded seedlings grow slowly. If you don't feel patient enough, you can keep the growing seedlings. However, it is not as good as the natural growth seedlings, and the later resistance will be slightly worse.
Where the light is not good, the seedlings will grow in vain. We must pay attention to basking in the sun.
