Hi Kitty,

I don't grow these (although I'm familiar with them).  I'm not sure
why they never found a home in my garden, though.

Barry Glick says those two plants are 'idiot-proof' and readily
propagated by either seed or division; some other random links online
said that spring or fall were both equally suitable for Zizia.

I don't know if that helps or not.  :D
