Acorus Plant Questions

1. What is Acorus?

Acorus, also known as sweet flag, is a genus of flowering plants in the family Araceae. It is a semi-aquatic plant that can be grown in water or moist soil. Acorus is native to Asia, but it has been introduced to many other parts of the world, including New Zealand.

2. What types of Acorus are there?

There are two main species of Acorus: Acorus calamus and Acorus gramineus. Acorus calamus is the more common species and is typically grown in aquatic areas. Acorus gramineus is a smaller species and it is often used as an ornamental plant in borders and the like.

3. How do I grow Acorus?

Acorus is a relatively easy plant to grow. Acorus calamus can be grown in water or moist soil, and it prefers full sun or partial shade. Acorus gramineus requires free draining soil and a full sun or partial shade position.

4. How do I care for Acorus?

Acorus is a low-maintenance plant, but it does need regular watering, especially during summer. They should be fed with a balanced fertiliser in spring. If plants get too large they should be divided or cut back severely in spring to encourage fresh, new growth.

5. Does Acorus spread?

Acorus calamus spreads with rhizomes, which are underground stems that can spread out and produce new plants. Acorus gramineus grows as a clump with smaller rhizomes and tends to spread more slowly. Both species will also spread via seeds when grown in the right environment.

6. How do you grow Acorus?

To grow Acorus here are a few tips:

1. Choose a spot in your garden that receives full sun or partial shade. They prefer a moist, well-drained soil.
2. Dig a hole that is twice as wide as the root ball of the plant. Dig it deeper and wider if you want to incorporate compost.
3. Place the plant in the hole and backfill with soil, firming it in gently to remove any air pockets.
4. Water the plant well and ensure it doesn’t dry out while it establishes.
5. Mulch around the plant with bark chips or compost to help retain moisture and suppress weeds.

7. How big does Acorus gramineus get?

Acorus gramineus, or Japanese sweet flag, is a semi-aquatic perennial plant that can grow up to 20 cm tall and wide. It has narrow, grass-like leaves and produces small, yellow-green flowers in the spring. However, the actual size can vary depending on the climate, the amount of sunlight the plant receives, and the type of soil it is planted in. For example, Acorus gramineus is likely to grow larger in warmer climates with full sun and moist, well-drained soil.
