(Federal place in Texas) goal is to plant a type of plant as a type of bio security around the fences to enhance the security to keep entruders from getting over the fences, but the plant needs to be unharmful towards the animals around the site. If you have any suggestions or anyone that we could possibly talk too for extra information we would greatly appreciate it.

use a Texas native and create wildlife value as you create a shield, plants from other areas will not do what you want

many of these look like holes in the wall, but one of them should be able to direct you to the grower
mix varieties, at least 5 species planted 3 deep, need only one or two to be nasty, others to fill-in so you have to push past nasty.

I'm interested in purchasing some native plants from your nursery for a hedge between us and the neighbors. I have 2.5 square acres in Oroville, CA and neighbors on only one side. We get a lot of rain in winter. On the neighbors side I wanted to put a hedge of Ceanothus Tassajara Blue Ceanothus as a visual and sound break along the entire length of our shared fence (approx. 210-ft long). I also wanted the hedge to be intermixed with other natives to maintain resilience of the hedge to disease but still maintain a semblance of naturalness and provide a solid visual and sound break.. What plant mix, plant numbers, spacing and distribution do you suggest that you can provide to fulfill my requirements?
Your assistance would be appreciated!

ok, we're really low on Tassara blue and deer really like them we have twenty leftovers but you'd be better with Sierra cuneatus(which we're out of) or Blue Jeans
a mix would be best, but again the deer are a problem

I have 9 acres next to a riparian oak studded creek, but otherwise surrounded by housing and roads. I would like to plant ground covers, vines, shrubs and trees that are dissuasive to intruders, be they human or feral pets. I have recycled water throughout the site, and I'm in Roseville, which is just North of Sacramento. What do you have that would be helpful in perimeter plantings?

Fremontia Californica (hates recycled water)
Rubus ursinus
Mahonia nevinii
Yucca
