However, it is a popular plant species among horticulturists and gardening enthusiasts due to its attractive elongated yellow flowers and unique facial appearance. It is also used in ecological restoration projects due to its ability to grow in damp habitats and stabilize soil erosion.
General Appearance
The Mimulus langsdorfii Donn ex Greene var. nasutus (Greene) Jepson is an evergreen perennial plant that grows up to one meter in height. It has an erect stem that has several branches, forming a dense shrub. The plant has cylindrical-shaped leaves that are 1-3 cm long and arranged oppositely along the stem. The elongated funnel-shaped flowers are 2-3 cm long, and their color ranges from bright yellow to orange. The flowers have two lips, with the upper lip being larger than the lower lip. The plant blooms from April to June, and the fruit is a capsule that contains several tiny brownish seeds.
Light Requirements
Mimulus langsdorfii var. nasutus is a shade-loving plant that prefers indirect sunlight. It grows best in areas with partial shade or filtered light. Too much direct sunlight can damage the leaves and cause the plant to wilt.
Temperature Requirements
These plants prefer cooler temperatures and do well in environments where the temperature ranges from 10-27°C (50-81°F). They can tolerate slightly higher temperatures but will wilt if exposed to extreme heat. In cold weather, the plant may become dormant but will revive when the temperature rises.
Soil Requirements
Mimulus langsdorfii var. nasutus needs moist, well-draining soil that is rich in nutrients. A pH range of 5.5-6.5 is ideal for optimal growth. The plant is susceptible to root rot, so soil that allows water to drain quickly is recommended. Adding organic matter to the soil can help improve drainage and provide nutrients for the plant's growth.

Propagation of Mimulus langsdorfii Donn ex Greene var. nasutus (Greene) Jepson
Mimulus langsdorfii Donn ex Greene var. nasutus (Greene) Jepson, also known as the sticky monkeyflower, is a native Californian plant species that grows in moist areas like marshes, meadows, and other wetlands. It has yellow-orange flowers with a distinctive long, straight tube. Propagation of Mimulus langsdorfii is generally done through seeds, cuttings, and division.
Propagation by Seeds
Propagation by seeds is the most common method. The ideal time to plant the seeds is in the spring or fall in a sunny location with moist soil. The seeds are tiny, so it's essential to use shallow but wide containers to provide ample room for growth. The soil should be constantly moist until germination, which can take up to two weeks. Once the seedlings reach 2-3 inches in height, they can be transplanted into the ground in their final location.
Propagation by Cuttings
Propagation by cuttings is another efficient way to propagate Mimulus langsdorfii. Cuttings are taken in late spring or early summer when the plant is actively growing. Choose branch tips with new growth and cut 3-5 inches from the tip. Remove the bottom leaves, leaving only a few on top, then dip the cut end in rooting hormone. Plant in well-draining soil and cover with plastic to retain moisture. The cutting should be ready for transplanting in approximately four to six weeks.
Propagation by Division
Propagation by division is an ideal method for already established Mimulus langsdorfii plants. It's best done during the early spring or late fall. Dig up the plant, and divide the root ball into two or more sections, each with its shoot and root system. Replant the divided sections into well-draining soil and water regularly. The plant should establish after approximately six weeks and begin to grow healthily again.
Disease and Pest Management of Mimulus langsdorfii Donn ex Greene var. nasutus (Greene) Jepson
Mimulus langsdorfii Donn ex Greene var. nasutus (Greene) Jepson, commonly called sticky monkey-flower, is prone to several diseases and pests that can cause significant damage if not managed properly. Here are some commonly observed diseases and pests of this plant and ways to manage them.
Diseases
1. Powdery Mildew: Powdery mildew is a common fungal disease that affects many flowering plants, including sticky monkey-flower. It appears as a white powdery coating on the leaves, stems, and flowers, causing them to shrink and distort. To manage this disease, use fungicidal sprays or systemic fungicides according to the manufacturer's instruction at the first signs of infection. Also, maintain adequate air circulation by spacing the plants appropriately and removing infected plant parts.
2. Verticillium Wilt: Verticillium wilt is a soil-borne fungal disease that affects many plant species, including sticky monkey-flower. It causes the leaves to curl, droop, and yellow, and can also induce stunted growth and wilting. To manage this disease, remove and discard infected plant parts, use resistant cultivars or rootstock, and avoid planting in highly infested soil.
Pests
1. Spider Mites: Spider mites are tiny sap-sucking pests that can cause severe damage to sticky monkey-flower by forming white webs on the leaves and sucking plant sap. To manage this pest, use insecticidal soaps or oils, increase humidity levels, and introduce natural predators like lady beetles.
2. Thrips: Thrips are small and slender sucking insects that damage sticky monkey-flower by eating the leaves and flowers and causing premature leaf drop. To manage this pest, use insecticidal sprays or systemic insecticides, improve the air circulation, and remove infested plant parts.
In summary, sticky monkey-flower is susceptible to several diseases and pests, but with proper management practices, it can thrive beautifully in a garden or landscape setting.
