An intriguing concept but, as commented on the landscape designer's
site, difficult to achieve.
I made a sundial with flower-beds in the hour segments but did not
attempt to find the "clock" opening or even sun following flowers.
I believe I showed this at the NASS conference in 1999.
What I found most difficult over time was merely finding plants which
would stay low enough not to shade the hours next to them.
I noticed that the list included some relatively tall plants.
Is it possible that the shading of a large blade gnomon might enhance
the opening delay or early closing of certain flowers??
