Plant guide

Hyacinth.

Hyacinthus orientalis

Pronounced hy-uh-SIN-thus or-ee-en-TAY-liss

Also known as Common Hyacinth, Garden hyacinth, Hyacinth, Wild Hyacinth

Hyacinths are beloved spring bulbs that produce dense, fragrant clusters of star shaped flowers. They are perfect for adding a splash of color to your garden or brightening up your home in late winter. These plants are grown from bulbs and typically go dormant after their blooming season.

Care

Plant your bulbs in well draining soil and keep them cool until they start to sprout. Watch for yellowing leaves after blooming, which signals the plant is storing energy for next year. Avoid overwatering to prevent the bulb from rotting in the soil.

Watering: Keep the soil consistently moist but never soggy while the plant is actively growing.
Feeding: Apply a balanced liquid fertilizer once growth appears in early spring.
Pruning: Trim off the spent flower stalks once they fade, but leave the foliage until it turns yellow.
Repotting: Bulbs are typically planted fresh each season or moved to the garden after indoor blooming.

Pets: The bulbs contain calcium oxalate crystals which can cause significant irritation if ingested by cats or dogs.
Children: Keep bulbs out of reach of children as they can be mistaken for onions and cause severe stomach upset if eaten.
Contact allergens: Handling the bulbs can cause skin irritation or dermatitis in sensitive individuals.
Airborne allergens: The strong fragrance may trigger respiratory discomfort or headaches in some people.

Growing it

Propagation: division, seed
When to plant: autumn
Overwintering: Leave the bulbs in the ground and apply a light layer of mulch if you live in a very cold climate. Ensure the soil remains well drained to prevent the bulbs from rotting during winter rains.
In containers: They grow very well in pots, provided the container has excellent drainage and is at least 15 cm deep.

Bulb Division

1. Wait for the foliage to die back completely after flowering.
2. Carefully dig up the bulb cluster.
3. Gently separate the small offsets from the main bulb.
4. Replant the offsets in a sunny spot with good drainage.

Plant these with low growing ground covers to hide the foliage as it fades after flowering.
