Originally we had the wrong plant as oppositiflora so sometimes I have to physically think out what I am talking about. Oppositiflora is a fine sort of plant with narrow leaves on a willowy small bush and a lot of orange flowers. It grows willingly to perhaps one metre and will probably flower year round in warm climates.
Propagation is by cuttings.
Oppositiflora in Betsy Clebsch’s New Book of Salvias is actually S. tubiflora.
