A friend purchased a Saguaro seed kit from her visit in Arizona.
I was sort of skeptical that these were so cheap (I had perhaps 100 seeds).
After researching, I found my catch: the growth rate of these guys is quite slow (as most cacti I assume)!
Well, they are about 5 months old now and are approaching one inch
I suppose they'll be a marker for the number of years of my friendship.
Amusingly, 3 of the 10 or so seeds popped up, got drowned by Louisiana rain on accident a few times -- and there are three of us.
One to each of us!
