This Echinocereus has usually curved spines equally colored or tips are darker, these seeds do not appear in cheap mixes.
More saguaro seedlings.
Saguaros are by 3 in a pot, for sale in DBG.
If your cacti mess in your job just forget about the job.

Don't discount carnegia on account of growth rate, heard lots of myths about how slow they are. In reality 1 to 2 inches a year is achievable. Derek bowdery here in the uk has a flowering specimen he raised from seed. It is bedded out in the greenhouse and it's taken 40 or so years if I remember rightly. Haven't been to his nursery for a little while.

I do not, not for the first instant, doubt that the little tiny small cactus i saw on display in the Arizona Sonora Desert Museum (remember that the sonoran desert is where most Saguaro grow and that the sonoran desert is WHERE the Arizona Sonora Desert Museum sits) was five years old just like they said. Yes, under special conditions almost anything is achievable. But why would the museum that is sitting in the desert they are showcasing resort to special conditions? They are going to display and explicate the desert that they are sitting in ... using the SAME conditions that exist IN that desert. Your 1 to 2 inches per year is achievable ... but you're not going to get that kind of performance from it's natural environment.

But is your plant "grown in its natural environment"?
Besides, in nature, only a small fraction of the seeds germinate, and even a smaller fraction reaches maturity. On top of that, some natural seedlings often dont grow in ideal conditions even in their natural habitats( lack of nutrients, bad soil...).And please remember, its a museum. Often some exhibits need be changed- and in all likeliness theyve might have changed the older seedling with a new one.
It takes 30 -50 years for a saguaro to flower in arizona(and by that time its usually taller than 3m/10 feet).
So, im gonna say it might have been just a show for tourists.

10ft in 50 years works out to be about 2 inches a year. Anyway, we are talking about plants in cultivation, usually with more water and nutrients than in habitat.
