Albury Purple St. Johns Wort

Where to Plant

• Sunlight: For the best berry production and the deepest purple foliage, plant in full sun (at least 6 hours of direct light). While it handles partial shade well, you may notice the stems stretching or the leaf color fading to a dusty green.
• Soil: This plant thrives in well-drained soil that doesn't hold standing water. If you have heavy clay, mix in some organic compost or plant it in a slightly raised mound to improve drainage and prevent root rot.

Watering Requirements

During the first growing season, provide about an inch of water per week to help the root system reach deep into the soil. Once established, Albury Purple is quite drought tolerant, though a lack of water during peak summer can lead to smaller berries and scorched leaf edges. Aim for consistent moisture at the base of the plant to keep the foliage looking lush and vibrant.

Pruning Tips

Because this St. John's Wort blooms on new wood, you should prune it back hard in late winter or very early spring before new growth starts. Think of it like a "reset button" that encourages a flush of fresh, colorful stems and more flower buds. Cutting the stems back to about 6 to 12 inches from the ground prevents the plant from becoming woody and sparse at the bottom.

Fertilizer Needs

Apply a balanced, slow-release fertilizer in early spring as the first leaves begin to emerge. Avoid using high-nitrogen fertilizers late in the summer because this encourages tender new growth that can be easily damaged by the first frost. A single application of an all-purpose garden food is usually enough to fuel its distinctive purple foliage and bright yellow blooms.
