What can I say. Some views are detrimental to your mental health !
What should I plant on my rooftop to block the view of that ugly building ? – this is something I have heard countless times.
Now … Throwing a plant in a pot and hoping it works – doesn’t work. Determining what are the characteristics the plant has to have to accomplish the needs is the better way. Here are some suggestions.
A sunny rooftop has some basic considerations; its sunny, tends to be windy, and its exposed to harsh winter winds. If we add another factor like “it has to be full and not see through” to block a view – our list gets shorter. Especially because that means putting in several plants in a row or cluster to make a hedge or screen.
Pretty view – hot, sunny, windy and totally exposed rooftop terrace !

Another important consideration – does it get insects or disease readily? – no point in putting something pretty that has to be treated every month ! Our list got a little shorter still…
Just because its evergreen doesn’t mean its a good choice. Alberta spruce with new growth damaged by spider mites – very frequent problem with these plants !
TRIED AND TRUE
These below are the tough ones – capable of handling rough rooftop conditions, while low insect and disease prone. Nothing else holds up better – unless you are talking plastic ! – and that discolors quickly – yuk !
These are good if you use the terrace year round, solid block when you are outside ! However, bonus is you can also enjoy them from inside during the winter when you look out to the terrace.
Arborvitae (Thuja occidentalis ‘Emerald Green’ ) – dark green leaves, tall, pointed growth at top, slow grower, top can be pruned and it gets more cylindrical over time.
