The Traffic Island garden is having a blissfully blooming summer.
There is only one problem: everyone is doing too well. Look behind the allium flower at the bottom of the image below and you'll see a Pelargonium (with red leaves) that has been subsumed by its neighbors. Hasn't died but not flowering either.
The Nasturtiums, Alliums and self-seeded Tanacetum parthenium 'Aureum'are doing so well out here that I think I am going to forgo the Pelargoniums in the future.
Perhaps add more coleus and call it done. This garden is in the middle of the street so it needs to be bright to be noticed.
When I bought the Pelargonium pictured below I did not realize it was a trailing variety. Though it is bright enough to be seen from a passing car, this image suggests it's best enjoyed close-up.
