Prickly Pear seeds are hard to come by and also hard to germinate.
Most Prickly Pear is propegated by cutting off and "ear" and rooting
that. From seed you would have to wait years before getting
flower/fruit. The ear method is much more reliable and produces
results much quicker. Your best method would be to find someone with
a Prickly Pear or buy one on-line.
I don't know of anyone reporting a method of seed treatment that has
been sucessful for this species. If you do want to try it, I would
suggest getting a ripe fruit and letting it rot in a little bit of
water, this produces good results with many succulent fruits. Some
acid or detergent treatment to mimic stomach acid is also a method
worth trying, but again, I don't know of anyone who has tested these
Depending on how dry you are: Oak trees in general are very deep
rooted. THere is Gambel's Oak (white oak family) in SW United states.
Also there are several scrub oak species (unknown genus/family) in
dry scrub above the valleys with Giant Redwood. Atleast the time I
was up their they seemed fairly prolific despite drought conditions
and growing out of a rock face.
I'm not sure about the root structure but Honey Mesquite (a legume)
is a desert species also here in the US (orginally texas, but spread
by over grazing)
Pinyon Pines are also a dry adapted conifers that servive in desert
climates. THere are two major species in the US and a couple in
Sand Drop seed is a bunch-grass from the short grass pairie (that
include yucca and prickly pear) although no improvement has been
done, several Naitve tribes used the seeds as a staple for porrige.
It has roots over 20 feet down.
Of course various Yucca species can be used, they are deep rooted.
Not my area of experise, but I believe the Oil Palm and Date Palms
are deep rooted? But they probably need some irrigation?
I beleive Gloria is from Texas, perhaps she knows where you can get
Prickly Pear, Mesquite, and yucca??
