Today I bought a small offshoot (is that the right term?) from the following plant and wonder if someone can identify it:
The parent plant has extremely sharp spines. The Amish greenhouse owner, who could not identify the plant, has had it for about a year, and this is the second offshoot it has produced during that time.
I have planted the offshoot in a two-inch pot containing equal volumes of moistened cactus/succulent potting mix and perlite, and the part of the offshoot where tiny roots appear to be forming is about 1/2 inch deep. It is sited in a east/southeast-facing window with bright sunlight.
Does this planting scenario sound hopeful or do I need to modify it?
Thank you for helping to identify this plant and/or sharing your expertise about growing it.
