[MENTION=14995]sisters3[/MENTION] why don’t you plant perennial flowers that grows up to 3’ high all along the very top row where your grass is. I would have a field day in there lol... Even if you have mulch you still can grow flowers. So this is I would do, at the very bottom step all along from left to right as I can’t see the length of your yard or basically where your mulch starts n ends, you get flowers that grows about a 8” to a foot high, middle section 15” to 2feet high, very top section where your grass is 2-3 feet high. Like a pyramid. Don’t plant one behind the other. So you start at the bottom put your flowers all along, middle section in between the bottom row, the very top row all along like the bottom row. Now bare in mind when you plant I’m sure you know that check the length n width of the plant you choose, the
#of hours of sun or daylight it needs. If at one end it’s shady you get a shady plant like hostas. OR....... put Hostas only. They come in many different colours, heights, sun, no sun etc. like the Elephant ears, they are massive but beautiful... These are tough plants. Even through our winters, never had issues with them. You can mix match them all throughout the mulch and add a few ferns. That would be the best way to go if you don’t want to break your head. When I plant flowers I always will think to plant the ones that flowers from spring to frost/winter so I gets flowers throughout all seasons. It’s a bigger job.
