This cultivar, part of the Agapanthus genus in the Amaryllidaceae family, stands out with its sleek, upright growth habit and the dramatic vertical accents it brings to garden landscapes.

The foliage is equally appealing, forming dense clumps of strap-like leaves that remain evergreen in milder climates. The deep green leaves provide a lush backdrop to the flowers, enhancing their visual impact and ensuring year-round interest.

With its graceful form, vibrant blooms, and enduring foliage, this Agapanthus is a superb choice for gardeners seeking a perennial plant that offers both beauty and resilience, effortlessly enhancing the landscape with its enduring charm.

How to care for your Agapanthus Streamline

• Planting: Prefers well-drained soil, so make sure to plant it in a location with good drainage. If your soil is heavy or clay-based, amend it with organic matter to improve drainage. Plant in a sunny location, preferably in the morning sun.
• Watering: Requires moderate watering. Water it deeply once or twice a week, depending on the weather conditions. During hot weather, you may need to water it more often, but be careful not to overwater it. Avoid watering the foliage, as this can lead to fungal diseases.
• Fertilising: Benefits from regular feeding. Apply a balanced fertiliser every two weeks during the growing season. Use a fertiliser high in potassium to promote flower production.
• Pruning: Deadhead the spent flowers to encourage new blooms. Cut the flower stalks down to the base of the plant once they have finished blooming. In the Autumn, cut back the foliage to about 15cm above the ground.
• Winter care: It is frost-tender, so protect it from freezing temperatures. In colder climates, dig up the bulbs and store them in a cool, dry place until Spring. In milder climates, mulch the plant with a layer of compost or straw to protect the roots from freezing.

By following these simple care tips, you can enjoy the beauty of Agapanthus Streamline in your garden for many years to come.
