Austrocylindropuntia subulata (Muehlenpf.) Backeb. is the accepted name for this species of cactus. It was described as such by Curt Backeberg in Cactaceae in 1941. It was first named Pereskia subulata by Philipp August Friedrich Muehlenpfordt and described in Allgemeine Gartenzeitung in 1845.

I found this little Austrocylindropuntia subulata (Eve’s Needle) from Wagler’s Greenhouse on 11-22-19 so I brought it home. I previously had an Austrocylindropuntia subulata f. cristata (Crested Eve’s Needle) that died in the winter of 2014. I forgot to measure this little plant when I brought it home…

<<<<2020>>>>

When I brought the plants inside for the winter on October 15 in 2020, the little Austrocylindropuntia subulata measured 4 1/2″ tall and already had an offset.

Austrocylindropuntia subulata is native to the high elevations of Ecuador and Peru in South America. They are a large tree-like species that can grow up to 13 feet tall. They have round cylindrical joints that can grow up to 2’ tall and 2 1/2 inches thick.

<<<<2021>>>>

I measured the plants on the from porch on August 17 in 2021 and the Austrocylindropuntia subulata measured 6′ tall and had another offset. The plant “was” in the center of the pot…

<<<<2022>>>>

When I moved the potted plants inside for the winter on October 16 in 2022, the offset of the original Austrocylindropuntia subulata measured 7″ tall. I forgot to repot it to put it back in the center of the pot. 🙂

It’s funny how the offset is now taller…

The species as a whole are a semi-hardy cactus that does NOT like temps below 25° F (-4°C). They prefer their night temperatures not to fall below 40° although the species can tolerate some light frost.

Repotting: Some information says they like to be “underpotted” while another says to provide adequate space for their “large root system”… Seriously, a cactus with a large root system?

This has been an interesting plant to watch grow and doesn’t seem to have any issues. 

You can read my Cactus Talk & Update and Cactus & Succulent Tips to get my opinion about growing cactus and succulents.

When you bring your new plants home from the store, you need to check their roots and the soil to see if they are wet. If so, you may want to re-pot it right away. It is advisable to re-pot them in a better potting soil more suitable for cactus and succulents.
