Low maintenance is one thing; and deer resistance at a weekend place is going to depend a little on the acquired tastes of the wildlife in your locality. There have been umpty ump threads about this on the Cottage Garden, Perennials, Plants for Difficult Places, etc. forums and the one absolute is that there are no absolutes from one person's garden to another's.

Also, if you search out deer resistant plants on the web, virtually every university extension has a site with big charts listing the regions typical plants and rates them as seriously, seldom, and/or rarely browsed. (Rabbits should also be a consideration - over the winter they'll chew down a lot of shrubs to nubs.)

Low maintenance could mean more shrubs that could go for quite a long time before needing any kind of pruning or shaping; and fewer blooming perennials.

In my experience, nepetas (catmint), salvias, Russian sages, artemesias, astilbes, peonies, PJM Rhododendrons, Northern Lights series azaleas, ferns, mugo pines, various spruce, creeping junipers, ninebark "Dart's Gold (chartreuse color), actaea pachypoda alba, Alpine currant, barberry (someone is going to say this is considered an invasive in some states), potentilla, and some things I'm forgetting, have never been touched by deer. I don't think they go for ornamental grasses, either.

Until you get your gardeing feet wet, annuals are always a good choice along with some good bones shrubbery. It's wired in wildlife DNA to ignore annuals and go for the expensive stuff.

I think the first thing is you need to seed the lawn with white clover. This will do two things one it will reduce the need to fertilize and it will keep The deer away from other stuff. Deer and rabbits love clover feed them that they will leave The other stuff alone. I'll leave it to The others to recommend plants. Just remember get a plan before you go to The nursery. Then try and stick to it. It's a cute house. If definitely needs some plants though.
Okay I can't resist. I see two weeping beeches framing The pourch. A bed with fluffy shurbs along The porch, perhaps verbinium or Chamaecyparis Pisifera With some seasonal perennials that bloom when you are there. There are some very nice herbs that grow low, often referred to as steppers, because you can plant them between those paver's and they give off a scent when you walk on them.

Is this house in The Hamptons? There are some great nurseries out there. Will you use it at all in the winter or spring?
