Just so y'all know, that picture of my room is when it's all cleaned up and organized!!

The conifer (blue-green) isn't doing too well but the star jasmine looks as though it just wants a bit of liquid fertiliser for extra nitrogen. It should then flourish and fill the boxes and you could then keep it clipped in a formal shape. It's pretty forgiving and you could prune it back if you don't like it sprawling, and give it a feed after. You could try cliveas, dark strap leaved plants that look rather like agapanthus, except they have fantastic orange flowers about now, and tolerate dry shade. Their dark green leaves look good all year round.

Every year I buy more bulbs to pot in various combinations. I bring the best ones inside when they're at their flowering peak. Grape Hyacinths and tiny daffodils with white and red freesias are my favourites so far. I love the scent of freesias, the brightness of daffodils, and the intricacy of ranunculus. I want to plant a big oblong tub of Ranunculus this year.
