There are, currently, common gardens at both UCEPC and SFS.
The new (established 1985) clonal plantation at SFS consists of 225 ramets derived from the same 10 female and 6 male genets that were used in the second clonal plantations at UCEPC. Nine of these genets had shown their respective constant floral phenotypes for the 11 years (1972-1982) of record in the original SFS plantation and the 4 years of record in the first UCEPC plantation.
Through 1991 all female and male ramets at the SFS and UCEPC have continued their absolute fidelity to "pure" male and female genotypes.
At SFS 103 plants produced from seed from the UCEPC clonal blocks were living in 1989.
