Disambiguation:
The two flower forms currently listed for this entry, pompon and incurved cactus are seriously at odds with each other. All of the photos in the database are of a cactus type dahlia.
Data World lists five different cultivars with the name 'Purple Gem', viz.
Purple Gem I Pom Pu. 1941 Barwise UK ir0/cd13/nds42w/adsc02
Purple Gem II SBa Pu. <1938 Dahlia News38
Purple Gem III SC Pu. 1965 ir0
Purple Gem IV MinD Pu. 1958 gw
Purple Gem V SC Pu. <1957 kops NL ir0/cd34/ =kops purple
Dahlia Addict references only an incurved cactus form, which seems to agree with the photos in the database.
I conclude that the database photos match either Purple Gem III or Purple Gem V in the Dahlia World list, and probably Purple Gem III, the most recently introduced of the entries. However, the database Year introduced (1941), Country of Origin (UK), and Hybridizer (Barwise) entries refer to Purple Gem I in the Dahlia World list. Likewise, the ADS classification code is appropriate to the pompon version (Purple Gem I), not a semi-cactus or incurved cactus form. I hope someone on the administrative side sees this comment and cleans up the data for this entry.
