Cupressus guadalupensis 'Greenlee's Blue Rocket' (Greenlee's Blue Rocket) - This is an evergreen upright-growing tree with silvery-gray foliage. This particular form was selected by John Greenlee from a group of seedlings. The oldest planted specimen exhibits a narrower growth habit than is typical. Although ultimate height and width are unknown it will probably grow to about 45 feet tall by 6-8 feet wide. In its native habitat on Guadalupe Island off of Baja California the species is known to reach nearly 60 feet tall with a broad rounded head. Plant in full sun. This tree is drought tolerant with a cold hardiness of 15 degrees F. Closely related to the Tecate Cypress, Cupressus guadalupensis var. forbesii has a range on the mainland from Mexico into southern California. Recent genetic research has shown that the Western Hemisphere cypresses are a well-supported clade quite separate from the Eastern Hemisphere cypressus. For this reason a new genus, Hesperocyparis, has been erected for the New World cypresses while the Old World plants will retain Cupressus. We are currently leaving this plant as Cupressus until this change becomes widely accepted. We were given this plant by John Greenlee in the mid 1990s as a fastigate form of Cupressus guadalupensis that he had selected from a seed lot that was grown by and from seed collected by David Amme. In 2001 we took our first cuttings of this plant and the following year offered up our first crop of it. This was the first time this plant was being sold and it lacked a cultivar name, so to help describe its unique erect form with blue-gray foliage we named it 'Greenlee's Blue Rocket' and first listed it in our 2002 catalog as such. More recently we have seen this plant also called out by the name "Greenlee's Silver Rocket", which while also descriptive, is not the name that we have grown this plant as since it was first introduced in 2002.  The information on this page is based on research conducted in our nursery library and from online sources as well as from observations made of this plant as it grows in our nursery, in the nursery's garden and in other gardens that we have observed it in. We also will incorporate comments received from others and always appreciate getting feedback of any kind from those who have additional information, particularly if this information is contrary to what we have written or includes additional cultural tips that might aid others in growing Cupressus guadalupensis.
