Description:
A shade-garden standout, ‘Glen 40’ dazzles with luxuriant deep red, formal-double flowers that glow against polished evergreen foliage in the quiet months of the year. Equally striking as a specimen, flowering screen, or trained as espalier, this classic japonica brings refined structure and winter-to-spring color to foundations, courtyards, and woodland borders.
Care Tips:
Plant in well-drained, acidic soil amended with compost or pine bark; keep roots cool with a 2–3" mulch (do not mound against trunk). Water deeply and regularly the first season, then maintain even moisture—especially in bud. Protect from harsh afternoon sun and drying winter winds. Fertilize with an acid-forming fertilizer after flowering, and prune lightly after bloom to shape (heavy summer/fall pruning can remove next year’s buds).
Landscape Uses:
Foundation accents, privacy screens, shade borders, containers near entries/patios, woodland gardens, espalier on walls or fences; pairs beautifully with pieris, astilbe, ferns, and Japanese maples.
Pet Note: Listed as non-toxic to cats and dogs.
