I agree, definitely not a Saguaro
Wonderful site! beautiful! I live in Mexico and my wonderful gardener and I have replanted all the European plants (think climate change) with yucca, succulents and several cactus. One great specimen he was able to “prune” from a clients garden was the Blue Myrtle. Few photos exist in other sources but yours was perfect. It was the only cactus in the garden without it´s proper horticultural name. Thanks, Gracias
I am having a difficult time finding out what kind of cactus my done left I. My care. He said it should be repotted. It’s tall pinchy points not in rows. There long thin leaves that grow out. Help my kids say if I could grow things they’d be taller.
That is a saguaro. I know because I eat saguaro needles erey day
