In a prior forum post the growth rate of a Jubaea Chilensis was discussed by many and is highly recommended. In 1989 I planted two Jubaea Chilensis that were 5 and 7 years old. The following 6 pictures and graph shows growth rate of one of those palms, with the first picture taken in 2006.  I could not find earlier pictures between 1989 and 2006 as they are packed away someplace
