Gymnocalycium is a genus of about 70 South American species. Their main area of distribution is Argentine, part of Uruguay, Paraguay, southern Bolivia, and part of Brasil. Most species are globose, rather small varying from 1.5 to 6 inches in size (4 cm to 15 cm).
They are popular for their easy flowering habits, although the flowers are generally brightly colored. They are also popular for their ease to care.
I bought some red sunflower seeds from this website. I also bought seeds from the big box store. The seeds I bought from this website sprouted first and look very robust. I am ordering more. Look for the next review once they bloom!!!
The seeds arrived quickly but we did not receive part of our order. We are still waiting for the ones we received to grow so too early for full review.
