I have had my David Austin Perdita rose for about 20, maybe 25 years. It started out in a large flower garden full of very old rose varieties and a few David Austin roses. The bed was solid clay. I was a beginner and gave up. I re-homed the roses...except Perdita. I moved it into a small raised herb garden that was where the lasagna bed now is. It lived there for a very long time. It stayed very small. The clay eventually came up into the raised beds and I gave up. I took the beds out and moved Perdita into my perennial border. It grows beautifully there. It never got more than about four feet in the clay beds, but now I have to cut it back a couple times per growing season so that it doesn't block out the kitchen window. Last year I started feeding the flowers for the first time. I took a lot of flowers out and replaced them with new varieties. I am going to put a couple bags of alpaca manure in the garden shortly. I cannot wait to see how this incredible rose looks this year.
