The Story
Plant Bio
Philadelphus, or mockorange, are deciduous shrubs cherished for their beautiful, pure white flowers that fill the late spring air with a sweet, orange-blossom-like fragrance. They are generally tough and easy-to-grow shrubs. 'Illuminati Tower' is unique for its tight, upright, columnar habit, making it perfect for narrow spaces. It is covered from top to bottom with fragrant, white, four-petaled flowers, and its dense branching provides good architectural interest.

Planting
How to Grow
- Choose a site in full sun or light shade with well-drained soil.
- Dig a hole twice as wide as the root ball.
- Place the plant in the hole, ensuring the crown is at soil level.
- Backfill with soil and water thoroughly.
- Water regularly during the first growing season to establish roots.
- Prune after flowering to maintain shape and vigor.
Pro Tip
Prune after flowering by cutting back the stems that have bloomed. This encourages new growth that will produce next year's flowers.
Keep It Thriving
Care Guide
Do
- Plant where the fragrance can be enjoyed, near a path or window.

Common Questions
Mockorange questions
What zones can Mockorange grow in?
Mockorange is hardy in USDA Zones 4–7. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.
Is Mockorange deer resistant?
Yes — Mockorange is rated deer-resistant. Deer typically pass it over, though extreme hunger can override any plant's defenses.
When does Mockorange bloom?
Mockorange typically blooms in late spring through early summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Mockorange need full sun?
Mockorange does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
Is Mockorange drought tolerant?
Yes — once established (usually after the first full season), Mockorange handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
