I haven't posted anything here in a while.

3. Borderline 6a.

Although they shifted the 5b/6a boundary outstate a LOT in the last revision of the zone map. 6a used to be just a little pocket in Metro Detroit, the urban heat island where I am, plus the immediate Great Lakes coastline from the St. Clair River to Toledo.

Now the 6a goes basically west to Lansing and north to Saginaw. There is a corresponding warm area on the west side from Grand Rapids to the Indiana border.

But, FWIW, most of the subtropicals are in pots. The only thing I posted from this batch of photos that is marginal and in-ground, to the best of my memory, is the silk tree in the Lounge post.

ON EDIT -- from this thread, the crape myrtle and the star fruit are potted and come indoors in fall. The rest are either annual or hardy.
