Agastache and Heuchera 'Circus'

I could not resist buying this container with Apricot, Raspberry and Orange Agastache.

It reminds me of fireworks!

I think I will plant it next to this aqua orb in the Arbor garden:

In front of the Agastache are two Heuchera 'Circus' that I just purchased.

I should probably separate the there colors.  I have never grown Aagastache before.  Those of you who know about this plant, what do you think?  Will they cross pollinate and produce muddy colors if leave them as planted in the container I bought?
