Is this property a rental? Dry shade, deer resisitant, spreads, maintenance free...vinca minor / periwinkle. Good for these purposes if you're not using it amongst other small plantings.

Acanthus mollis, Asparagus densiflorus sprengeri compacta, Dianella intermedia, Dianella tasmanica, Choisya ternata 'Sundance', Melianthus major, Euphorbia characias wulfenii, are a few plants that are both good in dry shade and deer resistant. Don't expect any of these to look great year round without some summer irrigation the first couple of years.

The only two natives I am really familiar with are the iris and the sage. If it is coastal, douglas iris can be grown from seed so that they are not so expensive. Hummingbird sage will fill in large areas. Neither are weed-blockers, though.

Thanks everyone! It is a rental, but the renters and neighbors are friends. I plan on installing a drip irrigation system to water the new plants at least until they are established, and depending on how they look they might continue to get occasional summer water. I was hoping that an asparagus fern would make it on to the list, yay!

Hellebores are very nice. If you know anyone with a Hellebore, they usually have seedlings to share.

My favorites! Asparagus ferns would propagate nicely under those conditions.
