'Joppi' is a spherical-growing dwarf form of Jeffrey Pine that will grow to 6 feet tall and wide over a 10-year period. The branches are brown with a Blue-lilac sheen over the young twigs. The needles are up 8 inches in length, thin, somewhat curved and dark green. When crushed the needles will exude a pleasant, lemony smell.
Piet Vergelt of Lottum, Netherlands discovered this cultivar in a bed of 3-year old Pinus jeffreyi seedlings and named it after his eldest son. In 1990 'Joppi' was awarded a silver medal during the "Herfstweelde" exhibition in Boskoop as well as a merit certificate in 1991.
