Research Memo No. 21 (1977) discussed the promising strobili production in the Vernon Arboretum.
The encouraging strobili production continued in 1978. Of the 285 surviving families, planted in 1976 as 4-year old grafts, 141 produced some strobili. Both male and female strobili were present. Some individuals produced over 100 female strobili while the largest number of male strobili on one individual was 478. One clone represented by 4 ramets produced 1037 male strobili. The table below summarizes the strobili production of families originating from various geographical sources.

Nearly 50 per cent of the earliest planted families, grafted 5-6 years ago, produced strobili. In contrast, the clone banks at the Red Rock Research centre produced practically no strobili: only 4 families produced female strobili and 12 families had some male strobili in small quantities. There are 430 families in these clone banks and the earliest ones were grafted in the spring of 1969. Some ramets are over 4 m tall with excellent growth rate.
