Sundials don't work when it's cloudy or dark (except when moon is exactly full). But Mother Nature can help.

Some flowers are heliotropic, that is they track the sun. Partly cloudy skies or even a complete overcast (if not too dark) doesn't stop them. All you have to do is attach some sort of hour hand to them and add a time scale. Overnight they move back from west to east for sunrise so they ought to even work at night (though probably not as accurately).

You have various flowers to chose from to complement and enhance your garden: buttercups, sunflowers or their leader, the heliotrope (whose color is the height of fashion right now).

       Welcome to the HB, [H&S]! Interesting notion. Bun for you. The only drawback I can see is the flower holding up the weight of whatever you use as an hour hand. But hey, that's pretty minor really. Probably best to stick to something robust, like a sunflower. Nice one.

       Some botanist (sorry, don't have a link) made a clock using the opening and closing of a number (probably 12) flowers to tell him the time. Apparently it worked quite well, once you learned the cycles of the various flowers.

       I bunned this because it is very nice, although what to use in a New England winter comes to mind.
