Are plants biologically immortal?

Unlike most animals, I've never heard of plants actually dying from old age.

No. Though some of them may be (some animals as well). Annuals (as the name suggest) live only for one year. The leaves on shrubs die every year, but the stem and roots remain alive. Something similar happens in perennial grasses. Plants are structured around tissues, and have few organs so it is hard to define "ageing". To add problems is the fact that no one really dies of "old age"; creatures die of age related stuffs; and for plants that have RELATIVELY simple organs and internal structures i have problem imagining what age-related problems they could have.
