Ibis. The first time I saw them was at my local Nursery. It caught my eye because as I walked past I smelled the wonderful fragrance. I picked up two of them because it was their beginning of the year 75% off sale I got two of them for under 10.00.
Lowes have them this year but they are in these body bags. I think because Knockout roses are really just a flowering bush and pretty darn hardy they should do good.
It is called Sunny Knockout.
