I think that, as "spin" points out, Genesis 1 is rather schematic, with environments being created, and then their inhabitants. Plants are viewed as an environment item, when we would more naturally view them as inhabitants.

Order can be established from the fossil record without reference to what is descended from what; the first stratigraphers had tended to believe in a Hugh-Ross-like view of special creations over geological time.

But just the same, it's clear that flowering plants became abundant only toward the end of the Jurassic, about 144 million years ago. Their ancestors were certainly around earlier, but for whatever reason, they left few fossils.

The first land animals crawled out of the rivers and lakes and swamps much earlier, during the Devonian (417 to 354 myrs), with arthropods doing it first, and then early fish/amphibians. I write it like that because it's difficult to tell where the amphibianlike fish end and the fishlike amphibians begin.
