Apparently guerilla gardening has come to Marrickville, with people taking over the grass verges in their streets. There's no grass verge on our street but I've noticed a few people have planted ornamentals around the trees. In our old street there was sage and rosemary around some of the trees.
I'd actually been thinking recently about planting nasturtiums around the tree out the front of our place, because it's a very hardy, attractive plant and both the leaves and flowers make a good addition to salads. I'm also intrigued by the recipe for nasturtium seed "capers" that I found in the River Cottage Preserves book.
Now if the nasturtium seeds I've had sown for a couple of weeks would just sprout already!
