2012 White House Spring Garden Tours: See Where Bo Plays, Michelle Obama Gardens (PHOTOS)

WASHINTGON -- See Michelle Obama's famous vegetable garden up close this weekend.

The White House is opening its grounds to visitors on Saturday and Sunday for the twice-annual White House Garden Tours.

Step into the Rose Garden, where you've seen countless bill signings and presidential addresses take place, and the beautiful Jacqueline Kennedy Garden.

The South Lawn of the White House will also be open to visitors. It's home to the enormous -- and recently replanted -- Kitchen Garden. It's also one of First Pet Bo Obama's favorite places to play, so look out for chew toys.

Check out the slideshow below to see John F. Kennedy addressing the first group of Peace Corps Volunteers, one of the country's first female members of Congress at a 1926 garden party, Michelle Obama planting veggies and other terrific moments from the White House gardens:

The White House Garden Tours will run on April 21 from 9:00 a.m.-4:00 p.m. and on April 22 from 9:00 a.m.-3:00 p.m. Tickets will be distributed on a first-come basis at the Ellipse Visitor Pavilion, next to the White House, beginning at 8 a.m. for each day's tours.
