According to that site neither Agastache barberi or A. mexicana are accepted specie names.
But here is a report on this plant from a nursery?
Interesting Notes
'Tutti Frutti' is a grand and vigorous agastache hybrid with narrow tubular blossoms of fairest lavender pink. It blooms for months in well-drained, sunny sites atop 4' stems of lightly scented green leaves. Try it with silvery Plectranthus argentatus, with a carpet of magenta Petunia integrifolia at its feet; You will love it! Hybridized from southwestern A. barberi and A. mexicana by Richard 'Salvia Man' Dufrense of Greensboro, NC.

So would we just leave all mention of what was used in the cross to make this hybrid?
