3.5" Astrophytum ornatum "Star Cactus"
Approximately eight ribs make up the composition of Astrophytum ornatum. It's gobular when young but somewhat columnar with age, with a star-like pattern on top. Spines are golden, approximately 1" in length and arranged marginally along the angles of the ribs. Requires bright light. Soil must have extra drainage; such as can be attained by addition of extra pumice or perlite. Water thoroughly when soil is dry to touch, but do not allow soil to remain waterlogged. A soggy star is not a happy star. Protect from frost.
