Janet,
 
Here are a few pictures I took of some of the purple hearts in ourgarden.   I know the settings look a bit scuffy (because, well,they are)
and the color depth as shown is less than it actually is (overcast day), but the photos ought at least to give you some idea of how the
Purple Hearts might work out chez toi.

Most cordially,

Dick
