These Astrophytums and a really great hybrid and grow into some of the most beautiful cactus plants. This one is one of 3 plants started from seed 2 years ago and the seeds were from Mesa Garden under the number 48 Astrophytum asterias superkabuto. This is a plant that should never be placed outdoors in a state like Wisconsin because they will usually die from fungal attacks. They will grow well in a sunny window, but it is very risky to put outdoors in a wet climate.
