<<<<<Perennial, Annual and Bi-annual

There are three types of plants--perennial, annual and bi-annual. A perennial 
plant is originally planted from seeds and grows every year without being 
replanted. An annual plant only grows the year it is planted and then dies 
off. If you want an annual to continue to come up, you must collect and save 
the seeds in the fall and replant them the next spring. A bi-annual grows the 
year it is planted and only one subsequent year after that before it dies 
off.>>>>>> 

This term is picked of a Google search as it does not appear in older books.  
Biennial was the term for many years.  I would suspect here that the 
familiarity with the term monocarpic and the other two might have evolved 
into bi-annual to clear up the difference to the gardener or buyer.

Monocarpic means the plant germinates and grows, any period of time, until it 
blooms and reproduces itself.  Then it dies.  This could be more than two 
years.  Sometimes many more.

Most of the plants classed as biennials do the job in two years although not 
always.  Some offset and live on.  It must be difficult for those listing 
plants in catalogs or classifying them in books as the growth descriptions 
can differ by individual or by location or by environment. This newish term 
may be an attempt to make descriptions clear.
