The Story
Plant Bio
Polemonium, or Jacob's Ladder, is a genus of perennials known for their pinnately compound leaves with leaflets arranged like the rungs of a ladder. They thrive in cool, moist, shady locations and produce clusters of bell-shaped flowers. 'Heaven Scent' is a remarkable cultivar that offers multi-season interest. It features fragrant, light blue flowers and fern-like foliage that emerges deep purple-maroon in spring before maturing to green, often retaining purple tips.

Planting
How to Grow
- Choose a location with part shade and rich, moist, well-drained soil.
- Incorporate organic matter like compost into the planting hole.
- Set the plant in the hole so the crown is level with the surrounding soil.
- Backfill with soil, firm gently, and water thoroughly.
- Apply a 2-inch layer of mulch to conserve soil moisture.
- Keep consistently watered, especially during dry periods.
Pro Tip
To maintain vibrant foliage color, provide morning sun and afternoon shade; deep shade can cause the purple tones to fade.
