Hydrangea Sister Theresa

Sister Theresa Hydrangea

Sister Theresa Hydrangea is a graceful lacecap variety prized for its pure white blooms and refined, upright habit. The delicate flowers, consisting of showy outer petals surrounding a central cluster of fertile buds, emerge in early summer and continue to display their charm throughout the season. Its compact, upright structure, typically reaching 3–4 feet tall, makes it an excellent choice for borders, foundation plantings, shaded gardens, or large containers. The rich green foliage complements the luminous white blooms, providing a clean, elegant backdrop and year-round visual interest.

This hydrangea is valued not only for its striking floral display but also for its dependable growth and low-maintenance nature. It thrives in partial shade, tolerates a range of soil conditions, and produces consistent blooms each year. Its sturdy stems support the flower clusters, reducing flopping and ensuring a refined garden appearance. Sister Theresa Hydrangea is also well-suited for cut arrangements, bringing classic elegance indoors. Whether planted as a specimen, in massed groupings, or as part of a mixed border, it offers timeless beauty, graceful structure, and long-lasting seasonal appeal.

Care Instructions

Planting:
Plant in partial shade with morning sun and afternoon protection. Place the root ball level with the soil surface and allow spacing for airflow and mature growth.

Watering:
Maintain evenly moist soil, especially during the first growing season. Water deeply 1–2 times weekly; increase during hot or dry conditions.

Pruning:
Prune immediately after flowering. Remove dead or damaged stems and lightly shape to encourage new growth and maintain form.

Pest Control:
Monitor for aphids, mites, and leaf spot. Treat with neem oil or insecticidal soap as needed, and ensure good air circulation.

Soil Tips:
Use well-draining, fertile soil with slightly acidic to neutral pH. Incorporate compost annually to enhance soil health and bloom performance.
