Native plants are good for
bees and neighbors can't really complain when you say you are planting a native garden. Native vetches will add nitrogen and flowers.

Camomile is a sturdy flowering plant that reseeds.
An important distinction: Permaculture is not the same kind of gardening as organic gardening.
Mediterranean climate hugel trenches, fabuluous clay soil high in nutrients, self-watering containers with hugel layers, keyhole composting with low hugel raised beds, thick Back to Eden Wood chips mulch (distinguished from Bark chips), using as many native plants as possible....all drought tolerant.
