Cast Iron Urn Planted 2020: Blue Salvia, Wave Petunia and Foxtail Fern

Documenting here, in the [garden diary] our front yard cast iron urn that I've planted the past few years.  I bought it off of Craigslist from a lady in LaGrange in the Spring of 2018 and we've kept it adjacent to our driveway ever since.  I'm not sure it is the best location, but for a variety of reasons, it has stayed put.  One change this year:  it is now sitting on top of a larger, square paver to give it a proper base.

Here's what we had in the urn last year - which was a bit more colorful.

This year, there are three plants in the container - with two of them being replicated from our backyard container that is based on a color pattern we saw in Paris at Luxembourg Gardens.

This has a larger Blue Salvia (Salvia farinacea), in front a red Wave petunia, and tucked into the upper left is a small Foxtail Fern.  We've had Foxtail Ferns in containers the past few years and have had mixed results - depending on how tightly we've packed them into the containers.  I've found that if we give them some room to breath - instead of crowding them into their containers, they seem to be happier - perhaps due to having more soil to allow for water absorption?

A few days ago, I posted a photo of the purple Coral Bells that we had in this container last year - and mentioned that we typically swap these Summer flowers out for Mums come Fall - or more recently those cool purple spikey flowers called Celosia Intez that I posted about in Fall of 2018.
