The olbio tree grew leaves upon which ysalamiri fed, and the creatures therefore lived on them most of the time. The forest on Myrkr was full of olbio trees, but the plant seldom survived being transported off-planet or transplanted in any way. Talon Karrde kept a large olbio tree full of ysalamiri in his base on Myrkr.
Although olbio trees appeared as early as Timothy Zahn's Heir to the Empire, the tree was not named until much later in Troy Denning's The New Jedi Order: Star by Star.
