A couple of volunteers and I are in the process of planning a memorial bench that we are going to build to place at the library for a little girl who was killed by her step father. We are trying to figure out what plants and flowers we want. The little girl's favorite color was purple, so it was suggested to look for purple knockouts due to their long bloom time. I cannot find a such thing. Does anyone know if these exist or have any other suggestions? I live in zone 5 and have very cold winters and do not want to place any plants or flowers that will need a lot of maintenance (as in digging bulbs up every fall). THANKS IN ADVANCE!!
I have had two Blue Girls in Zone 6, but they have not wintered well. However, their colour is more lavender, they bloom several at a time and the fragrance is to die for! I came across hybrids such as Ebb Tide, Rotesmeer and Reine des Violettes recommended for your zone. A very showy rugosa hybrid that is both hardy and gorgeous is Basye's Purple. I would also suggest you include in your design some great purple perennials such as purple alliums or crocus for spring and salvia, lavender, amsonia, bee balm, bellflower, lupines, liatris or phlox for summer perennials, some osteospermum for summer annuals, and purple asters for fall to keep that colour purple happening the whole season through! Best of luck with the lovely memorial.
The purple that was the little girl's favorite color is a challenging color to find in a rose, knockout or otherwise. The closest you would probably get might be a lavender. I don't think you should write off bulbs and other perennials so quickly. Alliums like "Purple Sensation" come back year after year, require no work, and really are purple. So is the catmint "Walker's Low," which blooms for a very long time. The perennial geranium "Rozanne" basically blooms none-stop. Add some purple iris, some salvia like "May Night" and some asters like "Purple Dome" and you will have a long-blooming, easy-care garden that truly celebrates her favorite color. For a final touch, add an arbor or trellis with a purple clematis like "Jackmanii."
Thank you all so much for the advice, I am attaching a picture of the "plan" of the bench. The flowers and plants in the pic were added by the designer just for show but we decided to go with a similar plan. Due to there being no such thing as purple knockouts does anyone have any ideas of what kind of bush or dwarf tree that can be placed behind the bench that would have long blooming purple flowers? I thing where the fountain grass is it would be pretty to place Alliums instead or even keeping the grass and incorporating the Alliums. I agree that a trellis or arbor with clematis would also be really pretty to! There are so many different types of plants and flowers that I am getting overwhelmed searching for what to put behind the bench! So THANK YOU SO MUCH for all the advice!
For many years Growers have been trying to create a deeppurple & a black rose. I think it will be a long time in the making, ifever. Many flowers labeled purple is not what most people think of as purple. You may want to look at a Barbara Streisand Rose from Weeks Roses. It may be the closest you will find to purple. I don't know where you live but it will not be a real hardy zone 4 rose
