What the gardeners own and send out under the name of Cl. erecta hybrida (i.e. bred integrifolia X recta), Cl. caerulea odorata and aromatica is fully identical. This hybrid distinguishes itself from Cl. integrifolia X viticella via richer inflorescences, extended sepals, which are not always wider at the tip and blooms of strong fragrance (like recta Flammula) with less pilous filaments; she is also often more branched. The plant blooms very floriferously from June until autumn.
