My dream is to be able to walk out of my back door into the back yard and enter a jungle.

The problem is when I walk out my back door now I can see 2 story condo complexes. I would like to plant some dense tall tropical looking screen(s)

There is nothing wrong with bamboo but I alrwady have some and I would like more variety than just bamboo.

I would like it to be 15' tall or taller if possible. A mixed screen might be interesting so I am anxious to hear suggestions.

WOuld oleander work ok as a screen?

Another great temporary screen is Ricinus communis (castor bean), the larger selections of which can easily grow to 15 feet in a single growing season.

I like the castor bean plants but I was afraid of planting them because they are posinous and I have 2 kids and 3 dogs.

I never knew cannas got that tall. I have some canna bulbs I purchased at home depot but I don't think they are supposed to get anywhere near 10' tall
