Plants I'm growing: First Blooms--Iris, Potentilla, "Altissimo" Climbing Rose, Bush Morning Glory

A lot going on in the garden today. I didn't have time to take many pictures, but I note here that this year's first blooms opened on a number of plants--including the first German iris of the year, the yellow potentillla under the olive tree, the "Altissimo" climbing rose, and the white bush morning glory (Convolvulus mauritanicus).

Yesterday a single blossom on the small pale pink Cistus under the Chitalpa tree opened, but I see no other flowers at the moment.
