Neal - good luck with moving the poppy. I hope you find the ideal place for it to bloom happily for years to come.
You did the right thing by carrying around a blossom - that's another Pamela Harper classic way of matching flowers to create more color harmony.
I kept thinking of this Japanese iris only as white, never considering the golden yellow flags. It almost begged to be planted here so the Zagreb coreopsis could show off the JI to full effect. Same story with JI Sing the Blues and the Asiatic lilies.
Then comes the disaster of having moved Easter lilies to the same area. I will relocate the Easter lilies since the scene is much too confusing for my eyes.
I do agree that a large swath of one plant, as well as planting in uneven numbers and not straight lines, is much nicer but it took me years of gardening to accept. My thoughts constantly ran to "What happens when that large area is not in bloom? Won't it look vacant?". Now I've calmed down and can accept every plant has its own turn to bloom. If any neighbor wants to be critical then let them show me their perfection! We who do the gardening work are often our own worst critics.
