Orange Bush Monkeyflower

Mimulus Aurantiacus

Mimulus Aurantiacus

Plant Overview

Known affectionately as the Sticky Monkey-flower, this vibrant California native is a superstar of coastal sage scrub and rocky hillsides. Its whimsical name comes from the belief that its flared, trumpet-shaped blossoms resemble the smiling face of a tiny monkey. Beyond its good looks, it is a rugged survivor, famous for its ability to thrive in harsh, sun-drenched environments where other plants might wither.

🔍 How to Identify

  • 🌸 The Bloom: Look for funnel-shaped, five-lobed flowers that range from deep apricot to a pale, creamy orange.
  • 🌿 The Texture: Rub a leaf between your fingers—the narrow, dark green foliage is covered in a distinctively sticky, resinous coating.
  • 🪴 The Form: It grows as a woody, multi-branched shrub, typically reaching 2 to 4 feet in height, often looking "wild" and sprawling.

🏡 In Your Garden

  • 💧 Drought Specialist: This plant is an expert at water conservation. Its sticky leaves aren't just for show; they help seal in moisture and discourage pests from taking a bite.
  • ☀️ Sun Lover: It craves bright light and well-draining soil. If you plant it in heavy clay or overwater it, the roots may suffer, as it prefers the "tough love" of a Mediterranean climate.

⚠️ Safety & Toxicity

  • Status: Non-toxic and generally safe.
  • 🐾 Details: It is not known to be poisonous to cats, dogs, or humans. However, the sticky resin can occasionally pick up dust or pollen, which might cause very mild skin irritation for people with highly sensitive skin.

✨ Fun Fact

The Sticky Monkey-flower is a favorite "fast food" stop for the Common Buckeye butterfly and several species of hummingbirds, who rely on its nectar during the dry summer months when other flowers have finished blooming!

Detailed Care Instructions

Here are some steps to help you grow Mimulus Aurantiacus (also known as sticky monkeyflower) successfully:

  1. Choose the right planting location: Mimulus Aurantiacus thrives in full sun or partial shade, so select a spot that receives at least 6 hours of sunlight per day. The soil should be well-draining.

  2. Prepare the soil: Before planting, amend the soil with organic matter like compost or aged manure to improve its fertility and drainage.

  3. Planting seeds or seedlings: You can either start with seeds or purchase young seedlings from a nursery. If using seeds, sow them in pots or trays in late winter or early spring. Cover the seeds with a thin layer of soil and keep them moist until germination, which usually takes about 2-3 weeks. Once the seedlings are strong enough (around 2-3 inches tall), transplant them into the desired location, spacing them about 12-18 inches apart.

  4. Watering: Water the plants regularly to keep the soil consistently moist but not waterlogged. It is essential to maintain adequate hydration, especially during dry or hot periods. However, be cautious not to overwater as it can lead to root rot.

  5. Mulching: Apply a layer of mulch around the plants to retain moisture, suppress weed growth, and regulate soil temperature. Use organic mulch like wood chips or straw, and avoid piling it against the stems to prevent rotting.

  6. Pruning: While Mimulus Aurantiacus doesn't require extensive pruning, you can selectively trim back any leggy or overgrown stems to maintain a compact and bushy appearance. Pruning can be done after the flowering season or as needed.

  7. Fertilizing: Apply a balanced, slow-release fertilizer in early spring to provide essential nutrients to the plant. Follow the manufacturer's instructions for appropriate dosage and frequency.

  8. Pests and diseases: Monitor your plants regularly and take necessary measures to control pests like aphids, spider mites, or whiteflies. These can be controlled with insecticidal soaps or organic remedies like neem oil. Additionally, ensure good air circulation around the plants to prevent fungal diseases.

  9. Propagation: If desired, you can propagate Mimulus Aurantiacus by taking stem cuttings in late spring or early summer. Remove several inches of healthy, non-flowering stem and dip it in rooting hormone before planting it in a pot with moistened soil. Keep the cutting warm and slightly moist until roots develop.

    Remember to check the specific needs of the cultivar you have, as certain varieties of Mimulus Aurantiacus may have slightly different requirements.

Preferred Location
Place in a window with dappled sun or a spot in the middle of a room. Or directly in a window facing west or east.

When to Water
To water this plant, you should make sure to regularly check the soil moisture to avoid over or under watering. The plant prefers well-draining soil, so it is important to not allow the soil to become waterlogged. When watering, aim for the soil rather than the leaves or flowers to prevent disease. Depending on the climate and time of year, the frequency of watering may need to be adjusted. In general, it is better to underwater than overwater this plant as it is drought-tolerant.

To fertilize this plant, choose a well-balanced, organic fertilizer with equal amounts of nitrogen, phosphorus, and potassium. Apply the fertilizer at the base of the plant, avoiding the leaves. Water the plant immediately after fertilizing to help distribute the nutrients to the roots. Fertilize this plant once every two weeks during the growing season, reducing the frequency to once a month during the dormant period. Over-fertilization can cause damage to the plant, so be careful not to apply too much.

The relative humidity levels between 30 and 50 percent are ideal for these plants. They exhibit unpleasant symptoms when the moisture content in the environment is unfavorable. Avoid letting the air temperature rise too high or low and use a humidifier, whenever possible. Misting is also beneficial, although frequent watering is also necessary. The optimal relative humidity will promote plant growth.

Mimulus Aurantiacus requires a well-draining soil that is rich in organic matter and nutrients. The ideal soil pH for this plant is slightly acidic, ranging between 5.5 and 6.5. A soil mix composed of equal parts of peat moss, perlite, and vermiculite is suitable for growing Mimulus Aurantiacus. This type of soil will allow water to drain away quickly while retaining enough moisture and nutrients for the plant to thrive. Avoid using heavy clay soils or those that are prone to waterlogging, as this can lead to root rot. Additionally, it is recommended to add a slow-release fertilizer to the soil mix during planting to provide necessary nutrients throughout the growing season.

Mimulus Aurantiacus is a perennial plant that can be propagated through various methods such as seed propagation, division, or stem cuttings.

One method of propagation is through stem cuttings, which involves taking a 4-6 inch section of the stem with a sharp, sterilized knife. The bottom of the stem should be cut just below a node, and all lower leaves should be removed. The stem cutting should be allowed to dry for a few hours before being dipped in rooting hormone.

The cutting can then be planted in a well-draining soil mix in a small container and kept moist until roots develop. Once the cutting has established roots, it can be transplanted into a larger container or directly into the ground.

Another method of propagation is through division, which involves digging up the plant and separating it into smaller sections. Each section should have roots and a portion of the stem and leaves. These sections can then be planted in their new location and kept well-watered until established.

Regardless of the method chosen, it is important to provide the young plant with adequate protection from the elements and regular watering until it has established itself in its new location.

Unfortunately, orange bush monkeyflower are susceptible to a host of common pests and diseases. Common orange bush monkeyflower diseases include Black or brown spots on leaves. Prompt pruning of any dead or diseased branches should keep these common diseases under control.
Common pests of the orange bush monkeyflower include Scale insect, mealybugs, spider mites, aphids. Make a habit of checking your orange bush monkeyflower frequently for pests so that any infestations can be caught and managed early.
