Cattleya aclandiae light rose to deep rose-purple. In cultivation, "C. aclandiae" prefers intermediate to warm orchid growing temperatures. Ample water is needed during periods of active growth; less water during the winter. High humidity is appreciated as long as adequate air circulation is present. Grow on cork bark or tree fern mounts or in pots with a coarse, free-draining growing media (fir bark or equivalent). Cattleya aclandiae Cattleya aclandiae ("Lady Ackland's cattleya") is a species of orchid from the genus "Cattleya", named in honor of Lady Lydia Elizabeth Ackland, wife of Sir Thomas Dyke Acland, 10th Baronet who was the first European
Basics of blue flower colouration of co-pigmentation, intermolecular and intramolecular. In the first type co-pigment is bound to anthocyanin by non-covalent bond (hydrogen bond, hydrophobic interaction, ionic interaction). In the second type, we can observe covalent acylation of the glycosyl moiety of anthocyanin. Intramolecular co-pigmentation has stronger effect on the colour. This type of protective stacking is called also a sandwich type stacking and is a very common mechanism in the formation of blue flower colour. Tirantin present in "Clitoria ternatea" (butterfly pea) and phacelianin present in "Phacelia campanularia" are examples of pigments with intramolecular co-pigmentation. Metal complexation: Often blue flower colour is correlated with
