This video by HTUKDave shows the life History of a Washingtonia Palm, from seed collection in 1992 to November 2009: 16 years.
Seeds came from the Canary Islands. They were collected by a hotel in South Tenerife in 1992. This Washingtonia robusta palm has grown in Chalk, Kent for 16 years, and survived various snowstorms and even a blizzard in Feb 2009. Although badly damaged the palmtree has recovered fully over the following summer.
