ON THIS PLANT

Mimulus alatus, the sharpwing monkeyflower, is an herbaceous eudicot perennial that has no floral scent. It is native to North America and its blooming season is from June to September. The flowering plant has green foliage and blue to violet flowers. It has a short life span compared to most other plants and a rapid growth rate. Like other monkey-flowers of the genus Mimulus, M. alatus grows best in wet to moist conditions and has a bilabiate corolla, meaning it is two-lipped. The arrangement of the upper and lower lip petals suggests a monkey’s face. The winged stems together with the monkey face give the plant its common name.

Temperature

Best cultivated in temperate regions, sharpwing monkeyflower prefers temperatures from 41 to 90 °F (5 to 32 ℃). For healthy growth, monitor and adjust temperatures during harsh seasons.

Fertilizer

Early spring, as it emerges from dormancy and begins active growth, is the ideal time to fertilize a Sharpwing monkeyflower. Fertilization supplies essential nutrients for healthy growth. Although Sharpwing monkeyflower has relatively low fertilizer requirements, applying fertilizer annually can enhance its survival and encourage better, longer-lasting flowers.

Pruning

The Sharpwing Monkeyflower is known for its distinctive winged stems and vibrant flowers. To encourage bushier growth and more blooms, prune the plant from early to late spring. During pruning, remove any dead stems and cut back about one-third of the plant. Be careful not to prune too heavily, as this can stress the plant and make it harder to control its spread. With proper care, you'll enjoy a robust display of flowers throughout the growing season.

FREQUENTLY ASKED

Reader questions.

How should I water my Sharpwing monkeyflower plant?

To properly water the Sharpwing monkeyflower, it is recommended to use filtered water at room temperature. Tap water should be avoided as it may contain harmful particles. The plant prefers warm temperatures, so using cold water can be shocking for its system. It is best to avoid overhead watering as it can cause issues with the foliage. Instead, water the plant by applying filtered room temperature water directly to the soil until it is completely soaked. This method helps to moisten the roots and promote their spread in the soil, allowing them to collect the necessary nutrients.

What are the sunlight requirements for Sharpwing monkeyflower?

Sharpwing monkeyflower requires a generous amount of solar exposure to thrive, performing well in both full sun (above 6 hours of sunlight) and partial sun (about 3-6 hours of sunlight) conditions. It's vital to observe how sunlight moves through your garden to ensure you're providing the optimal balance of light and shade for the plant's happiness. In its natural habitat, Sharpwing monkeyflower is accustomed to significant solar exposure, needing vibrant light throughout all growth stages for optimal development and flowering.

What is the ideal temperature range for growing Sharpwing monkeyflower?

Sharpwing monkeyflower, with its botanic name Mimulus alatus, thrives best in a temperate environment. The ideal temperature range for its growth is between 41 to 90°F (5 to 32°C). During harsh seasons, it's important to monitor and regulate the temperatures to ensure the plant's healthy growth.

If I either give my Sharpwing monkeyflower too much water or too little water, what should I do?

Overwatering and underwatering can harm your Sharpwing monkeyflower, but overwatering is more common. Too much water can cause wilting and yellowing of stems and leaves. It can also lead to diseases like root rot, mold, and mildew that can kill your plant. Underwatering is less likely, as this plant can tolerate drought. However, if it occurs, you may notice brittle, brown leaves. It's important to identify signs of overwatering early. Some diseases caused by overwatering, like root rot, may be irreversible if you wait too long. Reduce your watering schedule if you see early signs and check the soil's drainage. Replace poorly draining soil with a loose, well-draining potting mix. If signs indicate underwatering, water more regularly until the plant recovers.

How do artificial lights benefit indoor Sharpwing monkeyflowers?

For indoor Sharpwing monkeyflowers, when natural sunlight is insufficient, especially in winter or less sunny spaces, artificial lighting becomes crucial. It supports optimal growth and promotes faster, healthier development. LED lights are ideal for indoor plant lighting due to their ability to be customized to provide specific wavelengths needed by plants. Full sun plants require 30-50W/sq ft, partial sun plants need 20-30W/sq ft, and full shade plants 10-20W/sq ft of artificial light. The light source should be placed 12-36 inches above the plant, mimicking natural sunlight, and kept on for 8-12 hours per day, depending on the plant species' needs.

Does Sharpwing monkeyflower require frost protection?

Sharpwing monkeyflower exhibits strong cold resistance, which typically negates the need for special frost protection measures during winter. However, in instances where winter temperatures are expected to plummet below -25°C, it is advisable to provide cold protection. Covering the plant with soil or straw, and watering it abundantly before the first freeze in autumn to ensure the soil remains moist and enters a frozen state, can significantly help in preventing drought and water scarcity during winter and early spring.

How frequently should I give water to my Sharpwing monkeyflower?

If your Sharpwing monkeyflower is in a pot, the most precise way to determine if it needs watering is by checking the soil with your finger. If the top two to three inches of soil are dry, it's time to water it. The same method can be used if you're growing the plant outdoors in the ground. Once the top few inches of soil have dried out, it's time to water. Typically, during spring and early fall, you'll need to water this plant about once a week using this method. However, during extremely hot weather, watering may need to be increased to twice or more per week. It's worth mentioning that mature, well-established Sharpwing monkeyflowers have a remarkable ability to tolerate drought.

What are the symptoms of inadequate lighting for Sharpwing monkeyflower?

Sharpwing monkeyflower may exhibit several symptoms when exposed to inadequate lighting, including smaller new leaves, leggy or sparse growth, faster leaf drop, slower or halted new growth, lighter-colored new leaves, chlorosis, sunscald, leaf curling, wilting, and leaf scorching. These symptoms indicate the plant's struggle with either too much or too little light, affecting its photosynthesis process, growth, and overall health.

How does low temperature affect Sharpwing monkeyflower, and what should I do?

Sharpwing monkeyflower is notably cold-tolerant, thriving best when temperatures stay above 5°C. During winter, it is essential to keep the temperature above -20°C. If the temperature falls below -25°C, the plant may not show immediate changes, but there could be a decrease in sprouting or even complete lack of sprouting in spring. In spring, it is recommended to remove any parts of the plant that have failed to sprout as a response to these conditions.

How much water does my Sharpwing monkeyflower require?

To properly water your Sharpwing monkeyflower, don't hold back on the amount of water you give. Wait until the top two to three inches of soil are dry before watering. Give it a good, thorough watering so that the soil is completely soaked. Make sure to add enough water so that it flows through the drainage holes at the bottom of the pot. If you don't see excess water draining, you may have given too little water. Be careful not to let water accumulate inside the soil as this can harm the plant. On the other hand, if water is not draining through the pot, it could be a sign of poorly draining soil, which is bad for the plant's health. If the plant is outside, one inch of rain per week will be enough.

How can I improve the lighting conditions for my Sharpwing monkeyflower?

Improving lighting conditions for Sharpwing monkeyflower involves several strategies depending on the plant's location. Indoors, gradually moving the plant to a sunnier spot each week until it receives at least 6 hours of direct sunlight daily is recommended. Use south-facing windows for maximum sunlight exposure and consider artificial lights for additional support. Outdoors, it's important to introduce the plant to sunnier spots gradually to prevent sunburn. For ground plants, reducing obstructions like pruning trees can increase sunlight exposure. Transplanting smaller plants during their dormant period to sunnier locations can also be beneficial. Remember, while some parts of the plant may not recover from lighting issues, new growth after adjusting light exposure will be healthy.

What are the effects of high temperatures on Sharpwing monkeyflower, and how can I mitigate them?

During summer, it's crucial to keep the Sharpwing monkeyflower below 32°C. Temperatures exceeding 35°C may result in the leaves turning lighter, becoming prone to curling, sunburn, and, in severe cases, cause the entire plant to wilt and dry. To mitigate these issues, trim away the sunburned and dried-up parts of the plant. Relocating it to a shade or using a shade cloth to protect it from the midday and afternoon sun can be beneficial. Additionally, watering the plant in the morning and evening to maintain soil moisture is advisable.
