Diplacus ‘Eleanor’

Diplacus ‘Eleanor’ (formerly Mimulus ‘Eleanor’)

Overview

Diplacus ‘Eleanor’, or Diplacus x aurantiacus ‘Eleanor’ commonly known as Eleanor Monkeyflower, is a stunning broadleaf evergreen shrub known for its vibrant yellow flowers edged with white. It is a member of the Phrymaceae (Lopseed) family and was previously categorized under the genus Mimulus. Native to California, this plant is particularly valued for its drought tolerance, deer resistance, and its role as a larval food source for butterflies.

Background

The Diplacus genus, previously included in Mimulus, comprises a group of plants commonly known as Monkeyflowers. These plants are notable for their colorful, often trumpet-shaped flowers. The shift from Mimulus to Diplacus reflects taxonomic revisions based on genetic studies. Diplacus ‘Eleanor’ is a horticultural selection developed by Yerba Buena Nursery, named in honor of a former employee.

Care Instructions for Diplacus ‘Eleanor’:

Light

• Exposure: Full sun to partial shade. In coastal areas, it thrives in full sun, while inland locations benefit from light shade to protect it from intense midday heat.

Watering

• Frequency: Occasional to low. Water deeply and infrequently to establish roots. Once established, Diplacus ‘Eleanor’ prefers to remain relatively dry. Overwatering can be detrimental, as the plant does not thrive with consistent moisture.
• Special Note: Avoid using drip irrigation systems as they can overwater the plant. Instead, opt for occasional deep watering, particularly during the hottest parts of the summer.

Soil

• Type: Well-drained soil is crucial. Sandy or coarse-grained soils are ideal.
• pH: Tolerant of various soil pH levels but prefers slightly acidic to neutral conditions.

Fertilization

• Diplacus ‘Eleanor’ generally does not require heavy fertilization. A light application of a balanced fertilizer in spring can support blooming and overall health.

Pruning

• After flowering, cut the plant back to about 8 inches high to encourage regrowth and reblooming. Pinching the plant can help create a sturdy scaffold and prevent it from becoming too brittle.

Hardiness

• USDA Zones: 9b to 10b. This plant is well-suited to mild, frost-free climates. In areas with colder winters, it may require protection or be treated as an annual.

Propagation

Diplacus ‘Eleanor’ can be propagated through cuttings. Here’s a step-by-step guide:

1. Take Cuttings: In late spring or early summer, take 4-6 inch cuttings from healthy, non-flowering shoots.
2. Prepare Cuttings: Remove the lower leaves, leaving a few at the top.
3. Planting Medium: Use a well-draining mix, such as a combination of perlite and peat.
4. Rooting Hormone: Dip the cut end into rooting hormone to encourage root development.
5. Plant Cuttings: Insert the cuttings into the prepared medium, ensuring at least one node is below the soil surface.
6. Watering: Water the cuttings lightly and maintain moisture without making the soil soggy.
7. Environment: Place the cuttings in a warm, shaded area until roots develop. Once established, gradually acclimate them to sunnier conditions.

Landscape Uses

Diplacus ‘Eleanor’ is versatile in the landscape, suitable for various garden settings:

• Borders and Pathways: Provides a bright splash of color and attracts pollinators.
• Containers: Can be grown in pots, making it a flexible option for patios and small gardens.
• Wildlife Gardens: Attracts hummingbirds and butterflies, contributing to biodiversity.
• Under Oaks: Thrives in the dry, shaded conditions often found under oak trees.

Special Features

• Drought Tolerant: Once established, it requires minimal water.
• Deer Resistant: Typically not favored by deer, reducing the risk of damage.
• Pollinator Friendly: Attracts a variety of pollinators, including hummingbirds and butterflies.
• Verticillium Wilt Resistant: Shows resistance to this common soil-borne fungal disease.

In summary, Diplacus ‘Eleanor’ is a robust, low-maintenance shrub that offers extended seasonal interest with its continuous blooming and attractive foliage. Its adaptability to various light and water conditions makes it an excellent choice for gardeners seeking a resilient and visually appealing plant.
