Mushroom Plant, also known by its Latin name Rungia klossii, belongs to the Acanthaceae family.
This rare, fast-growing exotic plant is an unusual perennial variety native to Papua New Guinea. It typically reaches a height of 30 to 50 cm.

Mushroom Plant seeds are black, perfectly round, smooth, and measure only 2 millimeters in diameter.

Its leaves grow in pairs and are evergreen, thick, very glossy, and deep green, measuring about 4 cm in length.
Their most remarkable feature is their distinct flavor of button mushrooms.

Flowering occurs late in the year, during the autumn. The flowers are blue with hints of violet inside, tongue-shaped, and odorless.

- Planting and Cultivation:

• Plant mushroom leaves in a 5-liter pot filled with potting soil rich in organic matter, ensuring the root collar is at surface level.
• Line the bottom of the pot with a few centimeters of clay pebbles to ensure proper drainage.
• Water generously at the base immediately after planting.
• Place in a very bright spot indoors or in partial shade if grown outdoors.

- Soil Type / Substrate:

It thrives in a substrate rich in organic matter; a good quality compost is ideal. Avoid using compact, heavy clay soils.

- Exposure / Light:

Rungia klossii appreciates bright light but cannot tolerate direct sunlight.
A shaded or partially shaded exposure is highly recommended.

- Temperature and Hardiness:

This amazing plant grows best in temperatures between 20°C and 30°C.
Growth will stop if temperatures drop below 15°C. The Mushroom Plant is frost-sensitive and will not survive freezing temperatures; it must be brought indoors during the winter.

- Watering / Irrigation:

It is a "thirsty" plant that requires daily watering during the height of summer, but in small quantities.
If the foliage begins to turn yellow, it is a sign of overwatering. In this case, wait a few days until the soil feels dry. In winter, one watering per week is sufficient.

- Multiplication / Reproduction:

While growing from seed is relatively straightforward, the fastest and most effective method of propagation is through stem cuttings.
Cut a 10 cm shoot, remove the bottom row of leaves, and plant it in a pot of horticultural soil. For best results, use the "smothering" method (covering the cutting to maintain high humidity).

- Pests and Diseases:

The Rungia is generally disease-resistant. However, its leaves are a favorite of slugs and snails during the spring.

- Maintenance:

To encourage a high yield of leaves, it is recommended to prune the plant regularly just above the nodes.
This will result in a bushier, denser plant. Remove any yellowing leaves at the base of the plant as it grows.
