monkey flower


Commonly known as the common monkeyflower, this plant is well-recognized by its unique and captivating flowers. The blossoms are bright yellow, often dotted with red or brown splotches in the throat, which is quite pronounced. These throat spots are a distinct characteristic and are said to be attractive to the plant's pollinators. Each flower is tubular and flares out into a five-lobed mouth, almost like a typical "snapdragon" appearance. These appealing blossoms grow at the end of stems that can host multiple flowers. The foliage of common monkeyflower is generally a lush green, and the leaves are lance-shaped or oblong with smooth or slightly toothed edges. They can be found alternating along the stem, providing a dense green backdrop for the vivid flowers. It is a plant that may also show a slight variation in leaf coloration, ranging from light green to a darker, richer hue. The stems themselves are somewhat upright but they have a tendency to branch and can be sprawling. As a water-loving plant, it tends to grow along the edges of streams and wetlands, which is reflected in its foliage that seems quite at home in moist environments. It's common to see these plants forming clusters or stands in their natural setting, creating patches of bright yellow against the greenery along waterways. The overall impression of the common monkeyflower is one of rustic charm and enduring appeal, a delightful highlight to the banks it often calls home.

  • water dropWater

    The Monkey Flower, or Mimulus guttatus, prefers consistently moist soil, so water it regularly to maintain even moisture. Depending on the climate and weather conditions, watering every few days might be necessary, especially during dry spells. Typically, applying about 1 to 2 gallons of water per week should suffice, but adjust the amount to avoid standing water, which can lead to root rot. During hot, dry periods, more frequent watering might be required. Always check the top inch of the soil before watering; if it feels dry to the touch, it's time to water.

  • sunLight

    Monkey Flower thrives in full to partial sunlight. It ideally requires a spot where it can receive direct morning light but is sheltered from the intense afternoon sun, especially in hotter climates. This balance ensures that the Monkey Flower gets enough light without experiencing leaf burn or excess drying out.

  • thermometerTemperature

    The ideal temperature for Monkey Flower ranges between 60 to 75 degrees Fahrenheit. It can tolerate a minimum temperature down to about 32 degrees Fahrenheit and a maximum temperature of around 90 degrees Fahrenheit. However, for optimal growth and flowering, try to maintain the temperature closer to the ideal range and protect the plant from extreme temperatures.

  • scissorsPruning

    Pruning Monkey Flower is necessary to promote bushier growth and more blooms. Pinch back the tips of the stems in the spring to encourage branching. Additionally, deadheading spent flowers throughout the blooming season can stimulate further flowering. Prune the plant after the main bloom period or as needed to maintain its shape and remove any damaged or leggy growth.

  • broomCleaning

    As needed

  • bambooSoil

    The best soil mix for Monkey Flower (Mimulus guttatus) is a well-draining, loamy soil with a pH around 6.0 to 7.5. A mixture of peat, sand, and garden soil can achieve this, and incorporating organic matter like compost will help to ensure the soil remains fertile and retains moisture without becoming waterlogged.

  • plantRepotting

    Monkey Flower does not frequently need repotting as it can often be treated as an annual. However, if grown as a perennial, repotting every 2-3 years or when the plant appears to outgrow its container will be sufficient to maintain its health.

  • water dropsHumidity & Misting

    Monkey Flower thrives in moderate to high humidity levels. While it can adapt to average household humidity, ensuring humidity levels of around 50-70% will mimic its natural damp habitat and support its growth.

  • circleLife cycle

    Mimulus guttatus, commonly known as common monkeyflower, begins its life cycle with seed germination, typically occurring in moist soils along streams and wetlands. The seedlings quickly grow into herbaceous plants, producing simple, opposite leaves along their stems. During its vegetative stage, the plant focuses on accumulating resources and increasing its biomass. Upon reaching maturity, the monkeyflower produces vibrant yellow, bilaterally symmetrical flowers which are capable of self-pollination as well as cross-pollination through insect visitors. After successful pollination, the flowers develop into capsules containing numerous tiny seeds. The plant completes its life cycle when these seeds are dispersed into the environment, often by water, enabling the growth of new individuals.

      Spring-Early Summer

    • The most popular method for propagating Mimulus guttatus, commonly known as the common monkeyflower or seep monkeyflower, is by seed. Seeds can be sown in spring after the danger of frost has passed or started indoors about 6 to 8 weeks before the last expected frost. To ensure a higher success rate, it's best to surface sow the fine seeds on moist, well-draining soil, as they require light for germination. They should be kept at around 70°F (approximately 21°C) and usually germinate within 10 to 20 days. Care must be taken to not cover the seeds with soil, instead lightly pressing them into the soil surface ensures they have the contact they need without obstructing light. Regular misting is required to keep the soil damp but not waterlogged during the germination period. Once seedlings emerge and develop their first set of true leaves, they can be transplanted into individual pots or outdoor locations.
