Looking for a good security plant or bush.?

Question

I live in a tropical climate. The community I live is has alley ways behind the homes for utility - trash collection and such. Now we just moved into this home and removed a short chain link fence and installed a 6' tall wooden fence. There is enough space beyond the back side (facing out) of the fence to park a car. There is a concrete encasement, about 5' X 4' X 3' high, to keep the trash can in on non collection days. There is about 2 feet between my fence and the back of the concrete.
I just noticed the other day how easy it would be for anyone to stand on the concrete and jump over my fence. I would like to plant something there to make that very difficult. The space to plant is about 5 feet wide and 2 feet deep. Aesthetics are somewhat important, but it is in the back. Primarily the purpose is to block that area from a person who wishes to climb.

Thanks for any answers or suggestions.

Answer 1

Bougainvillea, They are thorny, woody, vines growing anywhere from 1-12 meters tall, scrambling over other plants with their hooked thorns. They are evergreen where rainfall occurs all year, or deciduous if there is a dry season. The leaves are alternate, simple ovate-acuminate, 4-13 cm long and 2-6 cm broad. The actual flower of the plant is small and generally white, but each cluster of three flowers is surrounded by three or six bracts with the bright colors. associated with the plant, including pink, magenta, purple, red, orange, white, or yellow. Bougainvillea glabra is sometimes referred to as "paper flower" because the bracts are thin and papery. The fruit is a narrow five-lobed achene.
Thorns are sometimes 3/4" long; http://images.search.yahoo.com/search/images/view?back=http%3A%2F%2Fimages.search.yahoo.com%2Fsearch%2Fimages%3Fei%3DUTF-8%26p%3Dbougainvillea%2Bplant%26fr%3Dslv8-adbe%26b%3D21%26ni%3D20&w=500&h=375&imgurl=static.flickr.com%2F231%2F487775753_4d45154148_m.jpg&rurl=http%3A%2F%2Fwww.flickr.com%2Fphotos%2F65215866%40N00%2F487775753%2F&size=253.7kB&name=487775753_4d45154148.jpg&p=bougainvillea+plant&type=jpeg&no=39&tt=774&oid=bdd2f86a4c0b109c&fusr=Fleur-de-louis&tit=Bougainvillea+Beauty&hurl=http%3A%2F%2Fwww.flickr.com%2Fphotos%2F65215866%40N00%2F&ei=UTF-8&src=p Pyracantha is also a great barrier plant. I used both to keep middle schoolers from jumping my back fence. I also had brambles (blackberries covering a section of the fence as well. My problem was 100% eliminated.

Answer 2

I suggest that the upper limit for contributions be done away with, and that the maximum payouts in retirement still remain as they are, adjusted for inflation. Social security is not a "give away" program but one that we all contribute to like a savings plan, and should be protected from other uses by the government. Do you agree or disagree and why? If you are so worried about it then why don't you; first put it back into the private sector and make to were no can take out money from it for their own interest, second pay back every penny you have borrowed from both Social Security and Medicare, third take the illegal immigrants off of it and those who come over here but never paid a penny to it, and lastly have it the same for everyone; in other words government officials are to participate in it and if they want something more they do it on their own without the tax payers funding it?Yet, the monetary stytem feeding the imbalances had never been really changed. They, a group of scholars, suggested that all interest rates would be 3% or less for everyone to become rich if desired (that must be true also to taces). The best economic situation would be, they said, when there were no interest rates. Why not try this solution? The rich would still be rich. My question is: when soial security becomes a problem connected to federal debts, why not work with a balanced or gain budget and spend no more than comes in, as any family has to strive for? Why not ban all loobying gifts in order to get laws that serve the country? God bless America.

Answer 3

I'd plant Rosa Rugosa rose or Barberry.
They're beautiful, easy to take care of, and thorny.

Rosa Rugosa can grow to 6 ft:

Barberry-Red Leaf Japanese
Berberis thunbergii

"Barberry by nature is extremely thorny, so any cultivar makes a great boundary marker/ privacy hedge. If you have an area that needs a deterent to trespassers this is the plant for you. No one will try and penetreate it and you get the bonus of it being extrememly beautiful." (some states prohibit it because it takes over an area.)

Good Luck! Hope this is helpful.

Answer 4

Pyracantha is deadly.... as is GREEN barberry.... I'd be careful planting berries, as they tend to spread and never go away.... these are the two that are really sharp thorns that I know of... besides them, there's the sharp-pointed holly bushes.... of course, it depends on what will grow well in your zone.... perhaps even roses.... there's some climbers that are wicked!.... you're doing a good thing.....

Answer 6

Try to find some bushes or shrubs with thorns--There are many to choose from and personally, I would look for some with small thorns. Or you could try to plant several catus'(sp?)

Answer 7

Thorney roses bushes or thorney blackberry bushes... the blackberry bushes will give you something yummy... you can try cactus too, but it may be too slow a growth... i remember too as a child thinking palmetto brush was very prickly...

Answer 8

Poncirus trifoliata, the Japanese Bitter Orange, very nasty thorns and wonderful foliage.

Answer 9

How about a nice bullhorn acacia? With or without ants.
