    About Westringia ‘Wynyabbie Blue’

    Westringia 'Wynyabbie Blue' is a hardy Australian native shrub grown for its lilac blue flowers, which are larger and more freely carried than those of the common white forms. Narrow grey green leaves sit in neat whorls on a dense rounded frame that holds its shape through the year.

    Expect 1.5 to 2 metres in height and width at maturity, at 30 to 60 centimetres a year. Full sun brings the heaviest flowering, though part shade is accepted. Drainage matters above everything else, after which it takes salt wind, sandy or gravelly ground, drought and light to moderate frost.

    Mass plantings on batters, median strips and coastal frontages are where it earns its keep, and it clips into a low hedge of about a metre without losing its flowering. Plant 1 to 1.5 metres apart for an informal screen. One plant fills a 40 to 50 centimetre pot neatly.

    Frequently Asked Questions

    About Wynyabbie Blue Coastal Rosemary

    What is Westringia Wynyabbie Blue?

    Westringia 'Wynyabbie Blue' is a hardy Australian native shrub grown for its lilac blue flowers, which are larger and more freely carried than those of the common white forms. Narrow grey green leaves sit in neat whorls on a dense rounded frame. It is evergreen and holds its structure all year.

    How big does Wynyabbie Blue grow?

    It reaches 1.5 to 2 metres tall and 1.5 to 2 metres wide at maturity, growing 30 to 60 centimetres a year. It clips comfortably to around a metre if you want a lower hedge, and it will hold that height indefinitely given two or three light trims a year.

    When does Wynyabbie Blue flower?

    From spring right through autumn, roughly September to May, with sporadic flowers in winter in mild districts. The lilac blue flowers open in flushes rather than all at once, so there is usually some colour on the plant. Flowering is heaviest in full sun on lean, well drained soil.

    Is Wynyabbie Blue drought tolerant?

    Yes. Once the roots are established it needs very little water and copes with extended dry periods, which is why it is used on unirrigated median strips and road verges. Drainage matters more than watering, since the plant will die in soggy ground long before it dies of thirst.

    Is Wynyabbie Blue suitable for coastal positions?

    It is. Salt laden wind, sandy soils and reflected heat are all handled, and it is planted routinely on foreshore reserves and beachside gardens. In very exposed frontal positions the plant stays lower and denser than it would inland, which generally suits the situation anyway.

    How far apart should I plant Wynyabbie Blue for a hedge?

    Use 80 centimetres between plants for a clipped formal hedge, or 1 to 1.5 metres for a dense informal screen. For mass planting on banks and median strips, 1 metre in a staggered pattern gives full coverage within about two growing seasons and shades out most weeds.

    How do I prune and care for Wynyabbie Blue?

    Trim lightly after each flowering flush, taking soft growth only. Cutting back into bare old wood leaves gaps that will not fill in, so stay on top of it rather than letting it get away. Water through the first summer, then rarely. Avoid rich soils and heavy fertiliser.

    Planting Information

    How To Plant Your Westringia ‘Wynyabbie Blue’ – Wynyabbie Blue Coastal Rosemary

    Site: Choose a well-drained position in full sun to part shade with room for the canopy to develop.

    Soil preparation: Enrich the planting area with quality compost and aged manure for a strong establishment phase.

    Planting: Position level with the surrounding soil, backfill gently, firm in, then water deeply to settle the roots.

    Recommended Planting Spacing For Your Westringia ‘Wynyabbie Blue’ – Wynyabbie Blue Coastal Rosemary

    Hedging and screening: 1 to 1.5 metres apart for a dense informal screen, or 80 centimetres apart for a tighter formal hedge.

    Pot or container: A 40 to 50 centimetre wide pot suits a single specimen for courtyards, entries and balconies.

    Long Term Care For Your Westringia ‘Wynyabbie Blue’ – Wynyabbie Blue Coastal Rosemary

    Watering: Water deeply twice weekly through the first 12 months. Once established, this is drought tolerant and only needs a deep soak during extended dry periods.

    Mulching: Apply a 3 to 5 centimetre layer of organic mulch over the root zone in the garden, or a thin layer of decorative pebbles in pots, keeping it clear of the trunk.

    Pruning: Tip prune in late winter and again in summer to build dense growth. For a formal hedge, light shaping two to three times a year keeps lines crisp.

    Fertilising: Apply a slow-release native blend in early spring and again in autumn. Avoid high-phosphorus formulations as a precaution.

    Pest and disease: Hardy against most pests and diseases. Occasional inspection in warm humid conditions is all that's needed.

    Plant Your Westringia ‘Wynyabbie Blue’ – Wynyabbie Blue Coastal Rosemary With:

    Enriched Planting Mix (AO Certified)

    Enriched Planting Mix is a certified organic blend of Pure Magic Compost, composted animal manure, gypsum, composted coarse bark and a wetting agent, bagged in 30L. It is built to be dug through existing garden soil at planting time rather than used on its own, and the gypsum is what sets it apart from a plain compost.

    Gypsum helps break up heavy clay so water and roots can move through it, while the compost and manure return organic matter and nutrient to tired ground. The coarse bark holds structure and keeps air around the root zone, and the wetting agent keeps moisture in the soil longer after rain or watering.

    Use it when planting trees, shrubs, roses, fruit trees and exotic garden plants, particularly into clay. Dig a hole twice the width of the pot and 7 centimetres deeper, then mix roughly one third planting mix through the excavated soil. Spread 7 centimetres of that improved soil in the base before setting the plant in.

    Frequently Asked Questions

    About Enriched Planting Mix

    What is Enriched Planting Mix made from?

    It is a blend of Pure Magic Compost, composted animal manure, gypsum, composted coarse bark and a wetting agent. Each part has a job. The compost and manure supply organic matter and nutrient, the gypsum works on clay structure, the bark keeps air around the roots and the wetting agent holds moisture in the soil.

    What plants is it suitable for?

    It suits exotic garden plants, including roses, ornamental and deciduous trees, fruit trees, shrubs and perennials, and it earns its keep most on heavy clay sites. It is a planting mix rather than a potting mix, so its job is improving soil at planting time. Phosphorus sensitive natives are the one clear exception.

    Is it safe for natives?

    No, not for the phosphorus sensitive ones. The composted animal manure in this blend lifts phosphorus well above what Proteaceae such as Banksia, Grevillea, Hakea and Protea will tolerate, and the result can be leaf burn, dieback and plant death. Use the Native Potting Mix for those species, or plant them into unimproved local soil.

    Is it certified organic?

    Yes. It is a certified organic product with no chemical additives, which is why the manure and compost in it are fully composted rather than raw. That makes it sound around fruit trees and vegetable beds, and it means you are adding genuine organic matter to your soil rather than a synthetic conditioner.

    How much do I need?

    Work on roughly one third planting mix to two thirds of the soil you dug out of the hole. For a shrub out of a 200 millimetre pot that is only a few litres. An advanced tree going into a large hole will take considerably more. Judge the quantity by the volume of the hole rather than the size of the plant.

    Can I use it in pots?

    It is not a potting mix and should not be used on its own in a container. The blend is designed to be diluted through garden soil, and used straight in a pot it holds too much water and settles badly. For containers, reach for a premium potting mix, or the native mix if you are potting natives.

    Does it need to be watered in?

    Yes. Water the plant well several hours before you plant it, then water thoroughly again once the hole is backfilled and the soil firmed down. That first deep watering settles the improved soil around the root ball and drives out air pockets. Keep the water up over the first few months while the roots establish.
