The Story
Plant Bio
Parrotia persica, the Persian Ironwood, is a small to medium deciduous tree highly valued for its incredible multi-season interest, including stunning fall color and beautiful exfoliating bark. 'Vanessa' is a distinct cultivar chosen for its upright, vase-shaped to columnar growth habit, which is much narrower than the typically wide-spreading species. This makes it an excellent choice for smaller gardens and street-side planting.

Planting
How to Grow
- Select a site with well-drained soil and full or partial sun.
- Dig a planting hole twice as wide as the root ball.
- Position the tree so the top of the root ball is level with the ground.
- Backfill with native soil, watering gently to remove air pockets.
- Water thoroughly once the hole is filled.
- Apply a 2-inch layer of organic mulch around the base.
Pro Tip
For the best fall color, plant in a location that receives full sun and has slightly acidic soil. The color is less vibrant in shade.

Care Guide
Do
- Water regularly during its first few years.
- Provide good drainage; it dislikes constantly wet feet.
- Allow the tree to develop its natural form with minimal pruning.
- Protect young trees from deer browsing.
Don't
- Don't plant in highly alkaline soils, which can cause chlorosis.
- Avoid planting in deep shade, as it will reduce fall color.
- Do not perform heavy pruning; it rarely needs it.
- Don't allow the soil to become compacted over the root zone.
