Nursery contributed plant descriptions

Urchin-like shape, slow-growing spine-free cactus. Light yellowish white tufts of fuzzy fuzz covers the areole that lines the center of the rib. Flowers appear from the center, petal color can range from plant to plant from white to orange. Usually seed-grown so each plant can look different from each other due to genetic makeup- so scale/speckle can have different density and pattern.
Astrophytum asterias, also called Sand Dollar Cactus, is a succulent species featuring adorable, rounded bodies divided into 8 sections. The grey green surfaces are adorned with varying styles of spotting, some more significant than others. Grow on a sunny windowsill in a well-drained medium, and allow soil to dry out between watering. Reduce water in winter. SO CUTE!
Keep dry in winter. Full Sun to Partial Shade. 2 inch wide Yellow Flowers with a Red center. Outdoor/Indoor.

These are great additions to our listing with plants selected for their super fleckings and markings. Outstanding plants. (These are small, young seedlings on their own roots. Therefore the price is low for the quality of the plants.) Photos soon.
