Can you help identify this succulent?
Shaped like a cone with thin spines
Drought Smart Plants reply:
Boy, it's a good thing you sent a picture - I recognize this one, as it's one of my favorite succulents of all time, but I would not have got that from the description!
This is Senecio mandraliscae, a relative of the string of pearls plant, Senecio rowleyanus if you can believe it. Sometimes closely related plants look nothing like each other.
You can see more about this easy to grow low maintenance plant on the miscellaneous succulent plant page - scroll down almost to the end to see it.
For more on succulent care look on this page. These are really easy to grow, and if they get too tall, really amenable to quite heavy pruning and propagation of the parts you cut off.
Happy Succulent Gardening!
