Bridgesii, Trichocereus bridgesii var. 'OTB' (10-12 inch Tip cutting)
Trichocereus bridgesii var 'OTB' or Old Town Bridgesii. A very special cut of T. bridgesii that is well favored by many in the community. One of my personal all time favorites for sure.
Trichocereus bridgesii, or Echinopsis lageniformis (as it has technically been renamed) is a very fast-growing columnar cactus from Bolivia. To the indigenous people of Bolivia it is often known as achuma.
