Lynn, if you search on the Royal Horticultural Society site here they usually give the correct naming, that is if the plant is listed.

To find the details I searched Agastache Tutti Frutti then clicked on the cultivar name Tutti Frutti.
Parentage: Agastache mexicana 'Toronjil Morado' × A. pallida subsp. pallida
As there's already a cultivar involved in the parentage that gets messy. If you have another place to put the parentage it would be good as many are obviously not giving the correct one.
