Graham Nicholls - Note: Campanula seraglio, this species is fairly new to cultivation and is in the same group as Campanula betulifolia, Campanula troegerae, Campanula choruhensis etc.Campanula troegerae Damboldt, sp. nov. [sect. Symphyandriformes (Fomin) Charadze]. Known to me only from the type gathering, this beautiful new Campanula is closely allied to Campanula betulifolia C.Koch (incl. Campanula finitima Fomin) from NE Anatolia. 3)
Related Species are Campanula thyrsoides (yellow bellflower, Canarina canariensis (Canary bell-flower) and Codonopsis tangshen (bellflower)Plant with low (10-15 cm) erect stems. The leaves are dark green, almost smooth, glossy. Flowers are among the items with 1-4 pubescent tips. It flowers in May and June with white or slightly pinkish flowers. 4)

Flower measuring, between 25 - 40mm (1 - 1 1/2 inch.)6)Flowers long-pedicelled, erect, to 12 on a stem, calyx with lanceolate appendages, corolla white od blue, flushed with pink outside, 1-1 ½ in. long, campanulate.
The genus Symphyandra is very closely related to Campanula and differs only in the anthers being connate in a tube. Even this difference breaks down, since in Campanula sect. Symphyandriformes there are some species, such as Campanula betulifolia and Campanula ossetica, where the anthers are partly connate in younger flowers. Also in Campanula flaccidula (sect. Rapunculus) the anthers are partly connate during anthesis (observation from herbarium material only). The preservation of Symphyandra as a genus seems to result from conservative tradition, and subgeneric rank may be more appropriate.7) Flowers are among the items with 1-4 pubescent tips. Corolla narrowly campanulate, up to 3 cm. It flowers in May and June with white or slightly pinkish flowers.8)

MATERIALS NEEDEDWhen breeding within a genus, the collection of all its species will help, since a few of them may carry a specific gene. In breeding for yellow color, why not try Campanula makashvillii, Campanula sulphurea, Campanula ereophilum, Campanula vidalii, Campanula thyrsoides, or Campanula betulifolia? Out of the 300 species available, we begin with the 180 we believe most suitable.11)
