|C. pityoides, is not the same as C. sieberi though they are both known as Alpine Bottlebrush. C. pityoides bears quite small flower spikes in pale yellow set against very pointed, narrow leaves in deep green, with a short summer bloom time. This evergreen shrub or small tree gets its species name citrinus from the lemony smelling oil glands present in the olive green, lance-shaped leaves. Spring to summer flowers are terminal, axillary, and crimson colored. Plant in neutral to acid, moderately fertile soil in full sun. This plant is tough and makes and excellent hedge. Regular prunning is not necessary. If you do prune, immediately after flowering is best.
