Granted Frodo's knowledge of this is probably inferior to Galadriels (who as you pointed out, would have had some degree of fisthand knowledge (though even she presumably has never seen every single inch of Valinor). But maybe Frodo was privy to some information, maybe Gandalf told him (with his mission fully fulfilled, Gandalf may have no longer been required to hide his origin so scrupulously, admitting to Frodo that he too had seen the Undying Lands might have been OK with Eru.)

According to the UT chapter "A Description of Númenor", mallorns were found in Eressëa, at least. Some seedlings were given to the Númenóreans, who later passed some on to Gil-Galad, who in turn gave them to Galadriel.
