I planted this daffodil as a teenager in the 70's. I remember my mother laughing and explaining what a 'backhouse' was! Every time it blooms, I marvel at the delicate coloring and remember how 'pink' it was at at time there were no other pinks available to the general public. In my opinion, it still holds its own in terms of its delicate trumpet coloring, shading from pink to peach to yellow.

I love my Mrs. R.O. Backhouse. My Grandmother and I planted it in the garden when I bought my House in San Juan Bautista, CA. in 1972. Along with most of the other daffodils we planted, it comes up faithfully every year, including this one. I don't remember the names of the other daffodils that we planted, but Gram told me the story of this one and even though she has been gone for 30 years, when it blooms I think of her and her pink cupped daffodil.
