Description and Traits
Myoporum parvifolium, known as creeping boobialla, is a versatile groundcover native to southern Australia. Its distinctive features and growth habits make it a popular choice for gardens and landscaping.
Botanical Profile
Myoporum parvifolium belongs to the Scrophulariaceae family. It’s a prostrate shrub that forms broad mats of foliage, typically spreading up to 3 metres in diameter.
You’ll find this species naturally occurring in southern parts of Australia, including Flinders Island. Its adaptability to various soil types and climates has led to its widespread use in gardens across the country.
The plant’s scientific name ‘parvifolium’ translates to ‘small-leaved’, accurately describing one of its key characteristics.
Leaves and Flowers
The leaves of Myoporum parvifolium are linear to narrowly oblong, measuring up to 50 mm long and 5-8 mm wide. You’ll notice they have entire or slightly toothed margins, giving the plant a delicate appearance.
Small white flowers adorn the plant, each having five petals with tiny purple spots. These flowers typically emerge from the leaf axils, either solitary or in small clusters of two to three.
The blooms provide a striking contrast against the green foliage, creating a snow-like effect when in full flower.
Growth Habit
As a prostrate groundcover, Myoporum parvifolium grows low to the ground, reaching a height of only about 30 cm. However, it spreads enthusiastically, often covering more than 1 square metre.
You’ll find this plant forms long, trailing stems that root as they grow, helping it to establish and spread quickly. This growth habit makes it excellent for erosion control on slopes or as a lawn alternative.
The plant’s vigorous spreading nature means you should consider its placement carefully in your garden. It’s ideal for areas where you want rapid ground coverage or to suppress weed growth.
Habitat and Distribution
Myoporum parvifolium thrives in diverse environments across southern Australia. You’ll find this hardy plant adapting to various soil types and coastal conditions.
Native Range
You can spot creeping boobialla in its native habitat across south-western New South Wales, central and western Victoria, and eastern South Australia. This versatile groundcover also calls Flinders Island home, where it grows on coastal salt plains.
In South Australia, you’ll encounter Myoporum parvifolium in several regions, including:
- Eyre Peninsula
- Murray
- Yorke Peninsula
- Southern Lofty
- Kangaroo Island
- South Eastern
- Green Adelaide
Climatic Zones
Myoporum parvifolium is well-suited to Australia’s southern coastal and inland areas. You’ll notice it thriving in Mediterranean climates with mild, wet winters and warm, dry summers.
This tough little plant can handle a variety of conditions. It’s often found in clay soils, sometimes in saline situations. You might spot it growing happily in disturbed habitats, showcasing its adaptability.
In its natural environment, Myoporum parvifolium typically experiences fire cycles every 10-30 years in Gahnia sedgeland or 10-100 years in Allocasuarina verticillata low forest. While fire kills the plants, their soil-stored seeds germinate after disturbances, ensuring the species’ survival.
Cultivation
Myoporum parvifolium thrives with proper care and conditions. You can easily grow this versatile ground cover in your garden with the right approach to planting, maintenance, and propagation.
Planting Conditions
Myoporum parvifolium is hardy in various soils and climates. You’ll have the best results planting it in a sunny spot. While it can tolerate some shade, too much will lead to sparse foliage.
Choose well-draining soil to prevent waterlogging. This plant adapts to different soil types, including sandy or clay soils. Before planting, improve your soil with organic matter if needed.
Space plants about 1 metre apart to allow for their spreading habit. This gives them room to create a dense mat of foliage. You can plant them closer if you want quicker coverage.
Maintenance and Care
Myoporum parvifolium is a low-maintenance plant, perfect for busy gardeners. Water newly planted specimens regularly until established. Once settled, they’re quite drought-tolerant.
Prune lightly to maintain shape and encourage dense growth. You can do this in spring or after flowering. Remove any dead or damaged stems as needed.
Fertilise sparingly with a slow-release native plant fertiliser in spring. Too much fertiliser can lead to excessive growth and fewer flowers.
Watch for pests like scale insects or caterpillars. These are rarely a problem but can be treated if they appear.
Propagating Myoporum Parvifolium
You can propagate Myoporum parvifolium through stem cuttings, seeds, or layering. Stem cuttings are the easiest and fastest method.
Take 10-15cm cuttings from healthy stems in spring or summer. Remove lower leaves and dip the cut end in rooting hormone. Plant in a well-draining propagation mix.
For layering, peg trailing stems to the soil. They’ll naturally root and form new plants. This mimics the plant’s natural spreading habit.
Seeds can be sown in spring, but they’re slower to establish than cuttings. Collect seeds from ripe fruit and sow in a seed-raising mix.
Uses in Landscaping
Myoporum parvifolium offers versatile landscaping solutions for your garden. This hardy plant adapts well to various settings and provides practical benefits beyond its aesthetic appeal.
Ground Cover Applications
