Start with the street name, because in Phoenix a street name is only half an address. The city is a grid across more than five hundred square miles, and every address on it is a coordinate: Central Avenue splits east from west, Washington Street splits north from south, and the numbers count outward from that crossing. The letter in front of a road is load-bearing. Two of the five shops covering this radius sit on the same road — Acacia Flowers AZ at 3150 E Cactus Road in 85032 and Fourseason's Flowers And Gifts at 6630 W. Cactus Road in 85304 — ten miles and a whole side of town apart. The hospitals do it too. The closest shop to the centroid, Florist Inphoenixaz at 2831 W McDowell Road in 85009, sits west of Central; Banner — University Medical Center Phoenix is at 1111 E McDowell Road, east of it. Same road, no turns, about five miles of straight driving — but only because somebody wrote the right letter. And underneath all of it, the oldest trap in the Valley: 7th Street and 7th Avenue are two different roads on opposite sides of Central, nearly two miles apart.
The serious medicine here sits in a band about two miles deep between McDowell Road and Thomas Road, which is the one convenient thing about distance in this city. Banner — University Medical Center Phoenix, 1111 E McDowell Road, is the teaching hospital for the University of Arizona College of Medicine – Phoenix, whose classrooms are back on the downtown biomedical campus two miles away, so the building with the medical school on the sign is not where the patient is. A mile north, St. Joseph's Hospital and Medical Center at 350 W Thomas Road carries the Barrow Neurological Institute, barely three miles from Florist Inphoenixaz. Two and a half miles east on that same road, Phoenix Children's Hospital at 1919 E Thomas Road faces Abrazo Arizona Heart Hospital at 1930 E Thomas Road across the traffic — two hospitals, one street, eleven digits apart, and no shared rules about what may come upstairs. Southeast of them, Valleywise Health Medical Center at 2601 E Roosevelt Street is the county's safety-net hospital and home of the Arizona Burn Center, the only one in the state. Carl T. Hayden VA Medical Center at 650 E Indian School Road stands a mile and a half north at 7th Street — 7th Street, not 7th Avenue.
Now what those buildings will actually allow through the door. Mayo Clinic Hospital runs one of the country's larger transplant programs, and its transplant and hematology floors exclude cut stems and potted soil as a category — the objection aimed at the standing water in a vase and the damp mix in a pot as much as at pollen, since both are places a fungus lives and a patient on immunosuppression has no margin for one. The same reasoning governs the blood and marrow floors at Banner — University Medical Center Phoenix and the Center for Cancer and Blood Disorders at Phoenix Children's, where pediatrics also declines latex and anything with small parts. At the Arizona Burn Center inside Valleywise Health the answer is simply no, for everyone; send to the family instead, since relatives spend weeks in the waiting areas on that Roosevelt Street campus. Barrow's floors rarely ban flowers outright, but they are the one place here where fragrance is clinical rather than social: someone recovering from a bleed is often in a darkened room with nausea and light sensitivity under active management. Behavioral units at Valleywise, and the state hospital on East Van Buren Street, restrict glass, wire and ribbon, which rules out most vessels before it rules out any flower.
