Additional comments: Jojoba is currently experiencing an upswing in
landscape popularity in the Phoenix area. Jojoba should not be planted in small
or narrow planters. Jojoba performs poorly if sheared. Jojoba fruit are edible, high oil content and
can be used
as a substitute for sperm whale oil. The leaves can be used in a
tea that will reduce swelling of multiple bodily mucous membranes.
In Mexico, jojoba teas have long been used for alleviating asthma. A
tea of seeds is reported to reduce inflammation in pharngitis,
tonsilitis and various types of sore throats. A functional
landscape substitute for boxwood in arid, hot sites. Very brittle
