The “Eggs and Bacon Plant” commonly refers to species within the Pultenaea and Eutaxia genera, both part of the Fabaceae (pea) family, native to Australia. Species like Pultenaea villosa, Pultenaea daphnoides, Pultenaea pedunculata, and Eutaxia obovata (also known as Eutaxia myrtifolia) carry this common name due to their distinct flower coloration.
Understanding the Eggs and Bacon Plant
The common name “Eggs and Bacon Plant” describes the unique appearance of its flowers, which typically feature bright yellow standards and red or orange wings, resembling a cooked breakfast. These pea-shaped flowers are a hallmark of the Fabaceae family. Both Pultenaea (about 100 species) and Eutaxia genera are endemic to Australia.
These plants are typically shrubs, varying in size from low-lying groundcovers to upright shrubs reaching up to 2-3 meters in height and width, depending on the specific species. For instance, Pultenaea villosa can form a graceful weeping shrub up to 2 meters high and 3 meters across. The foliage generally consists of small, often hairy, green leaves.
Caring for Your Eggs and Bacon Plant
Eggs and Bacon Plants generally thrive in full sun to light shade, preferring an open position where they can receive at least half a day of sunlight. Plants grown in heavier shade may become more spindly. They are quite adaptable and can tolerate a range of climates, including warm temperate, cool temperate, Mediterranean, and semi-arid conditions.
These plants require well-drained soil and can grow in various soil types, including sandy, loamy, sandy clay loam, or even gravelly soils. Good drainage is essential to prevent root rot. While some species appreciate moist soil with average drainage, they generally do not tolerate perpetually wet feet.
Once established, many Eggs and Bacon Plants exhibit good drought tolerance, reflecting their adaptation to arid environments. During the establishment phase, usually around 12 weeks, regular watering is important. After establishment, supplementary watering may still be needed during warmer summer months or extended dry periods, especially if grown in full sun.
These plants are generally frost tolerant, typically handling light frosts. Fertilization needs are minimal; some species, like Pultenaea, can be sensitive to phosphorus, so if fertilizing, use a slow-release native fertilizer with a phosphorus ratio under 3%. A diluted liquid seaweed product can also be beneficial.
Light pruning after flowering helps maintain a compact, bushy habit and encourages more flowers in the following season. For species like Pultenaea villosa, the natural weeping habit is best appreciated if the shrub is allowed to attain its full height and spread. Generally, these plants are resistant to most pests and diseases.
Propagating the Eggs and Bacon Plant
Propagation of Eggs and Bacon Plants can be achieved through both seeds and cuttings, with generally good success rates. For seed propagation, pre-treatment is necessary to break the seed’s dormancy and impervious seed coat. Methods like chipping, scarifying, or hot water treatment are all effective in aiding germination. Seeds can retain viability for many years.
When propagating from cuttings, use newer wood, often referred to as semi-hardwood or firm, current season’s growth, and remove the soft tips. Cuttings generally strike well, with some species rooting in about six weeks. However, constant misting should be avoided, particularly for hairy-leaved species, as it can lead to rotting due to water retention on the foliage.
Uses and Notable Characteristics
The Eggs and Bacon Plant is primarily valued as an ornamental garden plant due to its striking floral display and attractive foliage. Its dense growth habit makes it suitable for various landscaping applications, including use as a specimen plant, informal hedging, screening, or as a low-maintenance groundcover or in rockeries. Some varieties, like the dwarf form of Eutaxia obovata (‘nana’), are well-suited for smaller spaces or containers.
Beyond its aesthetic appeal, these plants contribute to the garden ecosystem by attracting pollinators such as bees and other insects. They are also notable for their drought tolerance once established, making them excellent choices for water-wise gardens or xeriscaping. The evergreen nature of the foliage provides year-round structure in the garden. They are adapted to specific native habitats, often found in woodlands, heathlands, or forests.
