Finally getting our yard in order and looking at the house, it looks very green (current bushes, grass) and brown / gray (house, slate steps). I really want to add some color but have no idea where to get started in terms of picking out bushes. Do they have to be planted small and grow bigger? Does the time of year to plant matter (as in, is it already too late to plant for this summer and have them bloom annually?) They'd need to be low maintenance - we do have a gardener come weekly to weed / mulch / mow / trim etc (had to after the yard got too much for us to bear) and I'm sure he could trim and plant etc, but would love some additional advice on what to choose.
Here are a few looks I like:
Any thoughts would be much appreciated!
