I was at the garden centre over the week-end and couldn't resist picking up a few pansies to put on my front and back steps. These annuals are super hardy and once hardened off, can be left outside at this time of year. Hardening off means gradually acclimatizing these soft, greenhouse-accustomed plants to the outdoors by starting to put them outside on a relatively warm day in a sheltered spot for short periods of time, and gradually increasing the exposure and amount of time. The afternoons should be fairly warm starting tomorrow so I'll ask my kids to put them out for a half hour or so starting tomorrow afternoon.
I love seeing flowers on the step when I come home from work! It's been too long!
