OMG Zoia - how many acres is your backyard
I am curious as to how you 'arrange' them. I would 'line out' some of my new purchases until I found a good spot amongst other plants but ultimately, with no new spaces, they didn't move
Then when that whole huge area of lined out hems bloomed it was a sore sight for eyes (note - not a sight for sore eyes
) Eventually I moved all 200 of the lined out ones to the Rainbow Bed - 100 feet of space on the east side of our driveshed - sorted by colour, dark purple one side down to white the opposite side. This is a much more peaceful arrangement
