It does have another element - it has Plant. :/ So you can get a Scoria from that combo - it's only if there are only two elements in the combo that the rule applies.

Plant + Iron is not recommended, partly because of long fail times like Scoria but mostly because the Moss dragon, which is a possibility from this combo, also takes 12 hours. (Try Plant + Chrome instead.)
