Rooftop terrace climbers (N-NE, highrise, 6-8h of direct sun,In pots, lots of WIND!)
I'm trying to solve a difficult problem
I own a green rooftop terrace in Belgrade, Serbia
Location 20°E 44°N
About 20m above street level
Exposed to winds form 3 sides (including famous Belgrade's strong easterly wind Kosava)
Gets 6-8h of direct sun
Strong wooden pergola with chicken wire sides for climbing plants
Currently there is no drip irrigation system but its planed for this autumn
Flora is inherited mixture of weeds, food crops, and flowering plants
And while in the "green part" of the terrace with little TLC many plants flourish(Calystegia sepium was my mothers climber of choice) in the exposed sitting area there are no plants
My idea is to build deep pots (~100x30x30cm)in corners by the wooden posts(1,2,3) and to plant vigorous and sturdy perennial climbers in order to create "green roof"
And there we come to the main problem:
WIND RESISTANCE! (+drought +frost +availability)
Main idea is green roof (red) but also side cover would be nice (orange). Sent, flowers, fruits and all other beautiful stuff is a plus but not the key
My ideas include Kiwi, Jasmin, Hops, Grape vine, Rambling roses, Visteria , Clemantis...
What plants would you recommend?
I found this that fits the "resistance+cover" bill
Crimson glory vine
Crimson glory vine
for which I dont know the local name or if its available in my region
Does someone in my neighborhood has that one?
Should i train chosen perennial climber though the wire (its is slightly moving in the wind)or go strait up around the posts and then use new growth to "drop" it down the sides.
Should i try planting now or wait until spring?
I hope that you can answer some of my questions and help me to find the best plant or mixture of plants for my purpose.
And for sure, if you find this topic interesting, i'm more than willing to share more pictures of the "green roof project" as it goes along
And/or discuss growing different plants in these tough conditions.
Thanks in advance
