Lochinch Butterfly Bush

Buddleja ‘Lochinch’ is a named hybrid shrub with arching branches, gray-green leaves, and fragrant violet-blue flowers marked by orange eyes. The RHS reports mature height and spread of 1.5–2.5 m; the Buddleja Collection describes an approximately 2 m plant and says its parentage is believed to include B. davidii and B. fallowiana. [RHS profile](https://www.rhs.org.uk/plants/91436/buddleja-lochinch/details) · [Buddleja Collection](https://www.buddlejacollection.com/plants/lochinch/) ## Form and placement The RHS describes long, slender flower panicles and an arching outline, and lists full sun or partial shade with well-drained soil. The Collection records summer flowers and recommends the shrub for borders. Its published 1.5–2.5 m spread corresponds to roughly 5–8 feet, while estimates vary by site. ## Growing conditions Choose a bright position with soil that drains freely. The RHS accepts both Buddleja davidii ‘Lochinch’ and Buddleja fallowiana ‘Lochinch’ as former names; the Collection describes the hybrid parentage as a belief rather than a settled cross. No USDA hardiness zone is proposed from UK-specific information. ## Maintenance The RHS assigns this selection to pruning group 6. Use the locally appropriate timing for that group and remove faded flower spikes as needed. Check new growth for aphids or leaf spot if symptoms appear.
