Genesis 1 states the following order of creation:
1. Heavens and the earth. (Not Earth, not sure why; it's covered in water.)
2. Light; night/day.
3. Sky. (In the KJV, it says it is "Heaven," probably multiple words in Hebrew that have one equivalent in English.)
4. Land, vegetation.
5. Sun and moon; stars. (Arguably, time.)
6. Sea creatures and birds.
7. Land creatures and man.
Genesis 2:
The universe is complete, so it "zooms in" to look at the Garden of Eden--plants and herbs "of the field" have not yet cropped up because of a lack of rain. God sends a mist from the ground to water them so that they will grow.
Then God creates man, described as a "living soul." (Interesting way to put it.) God sticks Adam in Eden--trees are already growing here, unlike the vegetation of the field.
Then the whole "serpent with fruit" bit comes into play. Let's look at God's curse on Adam:
"...[C]ursed is the ground for thy sake; in sorrow shalt thou eat of it all the days of thy life;
Thorns also and thistles shall it bring forth to thee; and thou shalt eat the herb of the field."
God has cursed Adam to work the fields for his disobedience, telling him that he will eat the "herb of the field," those plants that had not yet grown.
And why had they not yet grown? Because man had not yet been cursed and thus there would be no one to care for them. So, while other vegetation had grown on the third day, the field-plants/shrubs had not.
