just got this cute plant, I got one hot pink, one pink, one yellow, 3 reds and 3 sort of maroon color-very other-worldly looking. Will be closely monitoring them. And for Ronster 1266-the plant staff assisted me but the description/care guide did mention adult size, water/sun requirements, etc. I find these guides really helpful. Failing that, or if given a plant as a gift, will look it up online. They are easily found even when using description only. As for the person asking why the little guys aren't getting bigger-they never will. A small plant and-best of all-they really like indoor living! dogsRbetter

This cactus has a very eye catching, exotic look. reasonable price, easy care, easy too find as well. You could find them from most of the Lowe's Home Depot. A spoon siz tall Gymnocalycium Mihanovichii is only $5 at Lowes. Water it only the soil is compleatly dry or it will kill the plant. I personlly like to pick up the small suckers, that will make the main glob grow faster.

unusual cactus. The top of this cactus is not a fruit or flower but rather the gymnocalcymium. It does not contain chlorophyll and survives only by being grafted to a robust stock plact such as hylocereus.
