The other day while walking on the tram road in Sabino above Tram Stop #1, I noticed a white flower which looked both familiar and different at the same time. I was fairly certain it was in the Four O’Clock Family (Nyctaginaceae) and was leaning towards something like a Wishbone Bush, a Four O’Clock which has white flowers, when I noticed another plant next to the first which was clearly a Trailing Four O’Clock or Windmills (Allionia incarnata). Problem solved: it was an unusual white flowered Trailing Four O’Clock. Brian Gersten pointed out that he had noticed and photographed a similar white flowered specimen a couple of years before in the same area.
Thanks Fred (and Debbie) for more great finds!
