For long screens like 60ft, an aggressive running type would be able to fill it in within 3-4 years only with 1 plant since rhizomes can run like crazy when they're traveling along a rhizome barrier and well fertilized, but it is a pain to put down such a huge rhizome barrier since a 60ft circle is almost like a week of digging. You could also just rhizome prune annually, but 60ft might still take a couple hours to go around the whole thing. You might want one of the fargesia or chusquea clumping species for this purpose and plant them about 6ft apart. You could even have multiple plantings since their canopies will fan out to fill in the gaps. Clumpers will grow a lot less aggressive than running types and be easier to maintain since new shoots will only appear a few inches a way each year as opposed to several feet. Bamboos also rarely ever go to seed.

I have a huge live ak and a huge magnolia. After the live oak drops its leaves, the magnolia starts to drop them. It is the end of June and I am still raking! The roots are poping up out of the ground and nothing will grow near it. Everyday that I look at the magnolia, I think how I would like to chop it down and get a pool! Maybe you need more of a tall shrub instead of a tree. What about a Crepe Myrtle? Althea? They both grow fast. Good Luck!

Blue Bayou and HU-525254581 and Embothrium, Wow, Thanks for all of your personal experience on the magnolias and helping me ID the Magnolia I grew from a twig! Getting personal gardening experience from all of you is great info and I learned a lot from all of you. And the cat knows everything, but he's not talk'n! Also the people at https://myperfectplants.com have been totally professional, and agree with all of you that the mail order magnolia did appear to be Little Gem and they are sending me a replacement tree. I was truly impressed with how nice they have been and how quickly they responded. I am a very satisfied customer and would recommend them highly to anyone wanting to buy from them. I'm going to give the poor Little Gem the best chance at life in zone 6b in Pittsburgh that I can and will be looking for a little microclimate in my yard, like HU-525254581 did. And blue bayou I saw how big the parent tree of my rooted twig was and I did give it room to grow! Glad to know I will have a big tree in ten years, I'm not so young anymore, and it has indeed been a fast grower!
