You can see the two new Mexican Fence Post cactus pups growing from the base of the older and established cactus.
I am very excited to see pups growing as this is the first time I have actually had Mexican Fence Post pups. We had several hard freezes in a short time two years ago and it harmed many cacti in our area. One of the consequences though is that many cacti started producing pups in order to ensure survival of the cactus through offshoots.
When cacti are damaged from a frost, it does not necessarily die right away. To save itself, it can throw out pups and flowers for seeds. In the photo you can see the black spots on the ground and those are the flowers from the Mexican Fence Post that fall to the ground and hopefully grow new pups. I will show you the weird looking flower from this cactus tomorrow.
