Philadelphus coronarius 'Illuminati Tower’

Philadelphus coronarius 'Illuminati Tower': Tall, Elegant Fragrance in a Narrow Form

Philadelphus coronarius 'Illuminati Tower' is a Proven Winners® mock orange that brings classic early-summer fragrance to gardens that need a slimmer, more vertical shrub. Abundant white blooms open along upright stems, filling the air with that familiar sweet mock orange scent while keeping the plant’s outline neat and space-smart. After flowering, dense green foliage maintains a clean, structured look, making it a strong choice for designs that rely on crisp shape as much as seasonal bloom.

Plant Characteristics:

• Height: 4–5’
• Spread: 2–3’
• Flower Colour: White
• Flowering Period: Early summer
• Foliage: Green foliage
• Sunlight Requirements: Full Sun to Part Shade
• Soil Requirements: Moist, well-drained soil; benefits from organic matter and consistent moisture

Uses and Benefits: Ideal for narrow foundation beds, tight side yards, and small garden spaces where fragrance is wanted but room is limited. Its upright form also works beautifully as a vertical accent in mixed shrub borders, or planted in a row to create a slim, blooming screen along a fence line. Place it near patios, windows, or pathways to enjoy the scent at peak bloom.

Care Instructions: Water regularly during the first season to establish, then water deeply during prolonged heat or drought to support steady growth. Prune right after flowering to maintain the narrow form and encourage strong new stems for next season’s blooms. Mulch helps conserve moisture and keeps roots cooler in summer. A spring top-dressing of compost supports healthy foliage and reliable flowering.

History: Part of the Proven Winners® Illuminati™ mock orange lineup, 'Illuminati Tower' was selected for its upright, narrow habit and its ability to deliver classic mock orange fragrance in a more space-efficient shrub, well suited to modern landscapes.

Final Thoughts: For a mock orange that stays slim, blooms generously, and perfumes the early-summer garden, Illuminati Tower offers a refined, vertical take on a timeless favourite.
