I think maybe it is because I have childhood memories of my grandmother's garden full of roses in bloom in June when school was out and I would spend practically all of my time at her house. Her half-acre lot was full of rose bushes and the only presents she ever wanted for Mother's Day were more roses.
In my small garden which has maybe 90 square feet to garden in, my roses sit in containers on the patio. The rest of the garden is given over to daylilies (although I stuck a few Oriental lilies in this spring), a crepe myrtle and the Forest Pansy redbud.
The Brown Velvet came from a nursery in Oregon that I found on line - Rogue Valley Roses. The Knockout rose (name unknown) came from the tractor supply store down the road when they were practically giving away what was left in their nursery. I have two other RVR roses, Incantation and Baby Pat Austin, that have not yet bloomed although they have buds. I went back and ordered two more rose bands from RVR to come next week. I'd like to have the patio full of container roses while the lilies grow in the garden.
