Is there a special term used to describe woody plants/trees that flower every other year?

Biennial is the term for flowers that bloom every other year.

Thank you. Yes, but my understanding is this is the term for a plant that starts from seed year one and blooms year two but at the end of this second year it dies and disseminates seed for germination for another 2 year plant cycle.

Is this also the term for trees or shrubs that bloom in alternate years?

Welcome!

You are correct that a biennial plant is one with a two-year life cycle. A fruit tree that produces every other year is described as "biennial bearing". I don't know if there is a term for flowering every other year in non-fruit plants.

I'm curious, what are some examples of trees or shrubs that bloom biennially?

Both my avocado and my lychee trees bear in alternate years. Sometimes they have the odd fruit in the off years, but for the most part it's every second year. Some citrus lean towards this habit also.

It may depend on the variety, and/or the region, but my avocado bloomed like crazy every year, but had very little fruit set in the odd years. They are known for that here. This past spring I got about 600 smaller than normal fruit from it . Then had the tree removed because it had overgrown it's space to the hazardous point.

Aha, that reminds me of pecan trees. The trees look the same every year, to my very casual level of observation, from way down at ground level, but don't make nuts every year. I don't think they are predictable enough to be called biennial though.
