The Story
Plant Bio
Mockoranges are deciduous shrubs celebrated for their highly fragrant, white flowers that bloom in late spring, resembling the scent of orange blossoms. They are generally tough and easy to grow. Illuminati Sparks is a compact variety with unique variegated foliage, featuring dark green leaves splashed and speckled with yellow. This bright foliage provides interest all season, even when the fragrant white flowers are not in bloom.

Planting
How to Grow
- Select a site in full sun or light shade with well-drained soil.
- Dig a hole twice as wide and just as deep as the root ball.
- Place the shrub in the hole, ensuring the crown is at soil level.
- Backfill with soil and water thoroughly to remove air pockets.
- Apply a 2-3 inch layer of mulch around the base.
- Water regularly during the first growing season.
Pro Tip
Prune right after the flowers fade, as mockoranges bloom on old wood. Pruning too late in the season will remove next year's flower buds.

Care Guide
Do
- Plant in a location where its fragrance can be enjoyed.
- Prune immediately after flowering to maintain size and shape.
- Provide consistent moisture, especially in hot weather.
- Ensure good air circulation to prevent powdery mildew.
- Remove a few of the oldest stems to the ground every few years to rejuvenate.
Don't
- Do not prune in late summer, fall, or winter.
- Avoid planting in poorly drained, waterlogged soil.
- Don't let the soil dry out completely for extended periods.
- Avoid heavy nitrogen fertilizer, which can reduce flowering.
- Do not plant in deep shade, which will reduce flowering and variegation.
