Alba Jupiter's Beard

Alba Jupiter’s beard is the white-flowered form of Centranthus ruber, valued for airy clusters above fleshy, blue-green foliage. The exact trade listing identifies it as Centranthus ruber 'Alba' and reports summer flowers; the [RHS profile for the related white form](https://www.rhs.org.uk/plants/93520/centranthus-ruber-albus/details) also describes late-spring and summer bloom. ## Site and size Plant in full sun and use ordinary well-drained garden soil. A [TheTreeFarm product profile](https://www.thetreefarm.com/jupiter-s-beard-white) reports mature dimensions of 24–36 inches tall and 18–24 inches wide, with butterfly visits. A separate perennial catalog gives a similar height and spread, so use those as approximate planning ranges rather than fixed limits. ## Garden use Its pale flower clusters provide a light contrast among darker foliage or beside red- and pink-flowered perennials. Allow space for a rounded clump and choose a site where its seasonal bloom is visible from paths or seating areas. Flowering can vary with climate and growing conditions. ## Maintenance Remove faded flower stems to keep the clump tidy and reduce unwanted seedlings. Water during establishment; after roots settle, avoid persistently wet soil.
