Rooftop deck- Container plant plan advice
I am stumped on plant ideas for my friends swanky modern rooftop deck (I said I would help him out...). It is cedar with black and lime green accents (lighting fixtures and cushions). There is a ton of wood with the privacy screening, suana structure, pergola and bar. The little bit of vegetation we can squeeze in is going to go a very long way in rounding off the edges and cooling the feeling of the place off.
There are 3 planter boxes. One measures 2x2, the other 20"x20" and the other is 14"x2'
In zone 5b, third story city deck meaning intense winter winds and intense summer sun exposure. Irrigation equipped.
The pallette I am throwing around in my head is burgundy with lime green and silver splashes. But im open to whatever (2) plants will provide good structure and a graceful, soothing presence above all else.
So far I am considering-
Miscanthus Sinensis 'Morning Light' in the small planter that is largely protected from winds.
The other two planters though i'm stumped.
I have accepted the fact that I am best not trying to force an Acer Palmatum 'Bloodgood' into those conditions. I was drawn to it primarily for its dainty branch structure and trainable canopy.
I am thinking a tropical annual arrangement for one of the boxes centred around Canna Lilly and Sweet potato vine. Not sure though...
Please help. I am seeking ornamental tree and/or compact shrub suggestions to work with the above conditions. Evergreen would be great but not a Boxus. Specimen that are good as stand alones as I think I am forced to vary each planter box.
Anything helps, im stumped!
