Since she marries Draco Malfoy, it would be reasonable to assume she was a Slytherin. However, J.K. Rowling has never told us one way or the other. See the Related Link below for more information on the character Astoria Greengrass.
Astoria Greengrass. She's two years below Draco. She's also a sister of his Slytherin fellow Daphne Greengrass, who was introduced in Harry Potter and the Order of the Phoenix (book). Later, in the epilogue, both have son called Scorpius Hyperion Malfoy.
It is unknown what Astoria Greengrass (Draco Malfoy's wife)'s Blood Status was, though in Chapter 37 of Harry Potter and the Deathly Hallows, Ronald Weasley tells Rose Weasley that Arthur Weasley would never forgive him for marrying Scorpius Malfoy, who he said was a pure-blood. If Scorpius really is a pure-blood, then his mother Astoria should be a pure-blood, too. However, Ron may not be right about Scorpius being pure-blood.
No, Astoria is only mentioned in the epilogue and is referred to as Draco's wife not Astoria as neither Harry, Ron, Hermione or Ginny know her name. However her sister: Daphne Greengrass was in Harry, Ron and Hermione's year.
Draco Malfoy went to school, and was in the same year as Astoria's older sister Daphne Greengrass. So it is likely that they meet through Daphne, of course as both families were pure-blood they might have known each other.
We never see him with a girlfriend during his years at Hogwarts (although he might have been dating Pansy Parkinson) but in the epilogue he is married to a woman whom he has a son with. During an interview with Melissa Anelli, J.K Rowling stated that it was Astoria Greengrass, the younger sister of Daphne Greengrass.
