The planting of Class Ivy by graduating seniors is a tradition at many colleges. While there is no such tradition extant at Columbia, planting ceremonies did occur on the Midtown campus, and there are indications that a tradition of class plantings briefly sprouted on the Morningside Heights campus during the first decade of the 20th century. In addition, Barnard College had its own tradition of 'Ivy Days.'
Class Ivy at Columbia
Columbia had a planting ceremony tradition dating back to at least 1875. At some point it seems that the tradition may have died out, perhaps as a result of the cramped space on the Midtown campus, or broken by the move to the Morningside Heights campus. Whichever the case, notes regarding the class of 1906 state that "an old Columbia custom, the Class Pilgrimage was revived. In place of the yew trees of former years, a class ivy was planted at the northwest corner of St. Paul's Chapel." In June 1907 the class voted to install a tablet to mark the location. A planting was held again in 1913 after a 'class pilgrimage' from the graduation ceremony site to Hamilton Hall. It is unclear when the planting tradition ended.
Ivy Day at Barnard
Barnard adopted a class ivy tradition in 1909, dubbed "Ivy Day", after previous attempts to plant class trees failed.  Clearly something is up with the soil in Morningside Heights. The tradition appeared to be ending 1913, when the Barnard ivy orator declared her oration was an obituary for the event which was being discontinued. Nonetheless, it appears the tradition survived through at least 1914.
Class Ivy at other schools
Plantings of class ivy at other schools have similarly long histories, and some have lasted to the present day. At the University of Pennsylvania, the senior class designs and installs an "Ivy Stone" at a location of its choosing somewhere on campus to commemorate their time at the college. The stone tablets typically bear the class year and an ivy motif in lieu of an actual planting. Seniors submit designs to competition to determine that years tablet design.

It is unclear what precisely was being revived, since Ivy Orators were still being selected as early as 1898, see e.g. Columbia University Bulletin, March 1898, Pg. 145. Perhaps 1906 marked the revival of a planting ceremony in addition to an oration. The reference to yew trees is also interesting since the 1875 mention is of ivy.
