A few tight spaces

I've been cooking up some leafy ideas for a friend's flat. First up is a large window box outside the kitchen sink, in full shade, on constant view - it's got to look green and luscious all year round.  No soggy lavender here.

I'm thinking a woodlandy planting of Dryopteris, Libertia and Dicentra.  The fern and Libertia are structurally evergreen, while the delicate Dicentra pops up in Spring, and after its flowers have faded, will remain in lovely fresh green leaf until November. Classy green and whites.

Libertia grandiflora

Dicentra spectabilis 'Alba'

Next on the hit list: a container tree for the exposed roof terrace.  Since it's not visible from the windows, nor going to be used much in the winter, I lean towards a deciduous tree, whose leaves will be absent during spells of harsh cold winds.  An Acer would be lovely, or perhaps a Birch or Amelanchier.  Whatever variety, I would go with a multi-stemmed form, to act as a green parasol against the city backdrop.

These Domani fibreglass cubes would make a very cool place for the tree to live:

Although on a smaller budget (Domani's pots take some saving up), Bright Green do a 'double skin' container that is similar (only up to 50cm though).

Last on the agenda is a wall on the roof terrace seen from the bi-fold doors year round, sheltered, and catching the west sun.  The climbing rose 'Mermaid' flowers on and off all year round, and is semi-evergreen:

This could live in a container, so long as the rose has enough REALLY good, rich soil to put its roots deeply into.  Up with the manure then...
