Hi DonfromPA,
At first I too was confused by the term NOID, if it were written slightly different as NoID the meaning would be more self-evident
A few semp-related terms were conjured in this forum, just for fun, so for a Semp arachnoideum without a name, I call them "arachNOIDs"
Here's an arachNOID I bought at a large garden center in 2018, which I used in an outdoor planter. Second photo is the same plant in my planter, November 2019.
