Blue Lace Flower

Blue Lace Flower (Trachymene coerulea, formerly classified as Didiscus caeruleus), is an annual herbaceous plant belonging to the Araliaceae family, the same as ivy, native to south-western Australia.

It is an uncommon species in Italian gardens, prized by enthusiasts for the rare elegance of its blooms and the touch of refinement it brings to borders and floral arrangements, standing out clearly from any more common flower.

The Blue Lace Flower Plant

Blue Lace Flower develops a branched, upright habit, with few light green leaves divided into small leaflets, concentrated mostly at the base of the plant: a natural choice that leaves the whole stage to the flowers. Within a few weeks it can reach 60-90 cm in height, its clump occupying around 35 cm of ground.

The flowers, a delicate lavender-blue, are in fact tiny five-petalled star-shaped florets, gathered into flat umbels 5-6 cm in diameter. The dense, regular texture of these small flowers closely resembles fine lace, a detail that makes this plant particularly sought after by those looking for something different from the usual.

How to Sow Blue Lace Flower

Sow in spring, from March to April, preferably in protected trays, or directly outdoors from mid-April in milder climates. Seeds should be lightly covered with fine soil, and germination usually takes 15-20 days at a temperature of around 18-20 degrees.

Given the delicacy of its root system, Blue Lace Flower dislikes transplanting: if sown in trays, it is advisable to use individual biodegradable pots so the plant can be moved outdoors without disturbing the roots.

How to Grow Blue Lace Flower

It prefers light, fertile, well-drained soil, in full sun or at most bright partial shade. Watering should be regular but moderate, avoiding both prolonged drought and waterlogging, which can damage this species' sensitive roots.

Flowering continues throughout the summer, adding a light, romantic touch to sunny borders, wildflower meadows or dedicated cutting gardens. The delicate scent of its flowers also attracts numerous pollinating insects, making it a valuable ally for garden biodiversity.

Growing Tips for Blue Lace Flower

Thanks to its long, slender stems, Blue Lace Flower is wonderfully suited as a cut flower: cut when the umbels are fully open, it keeps its elegance in a vase for several days, bringing a touch of refinement to any floral arrangement.

It pairs particularly well with plants of contrasting colours and textures, creating visually striking combinations both in beds and in pots on terraces and balconies.

Diseases and Pests of Blue Lace Flower

Blue Lace Flower is generally not very prone to serious diseases when grown in well-drained soil with good air circulation between plants. The main risk, as with many plants with delicate root systems, remains rot caused by excess moisture.

Occasional pests may include aphids on the youngest shoots, easily controlled with natural potassium soap treatments or a simple jet of water.

Uses and Curiosities of Blue Lace Flower

For a long time this species was known as Didiscus caeruleus, and many gardeners and catalogues still refer to it by this older name today, even though modern botanical classification places it within the genus Trachymene.

Its flowering, which resembles that of Scabious in structure, brings a subtle, almost romantic charm even to the simplest setting, making it a perfect choice for anyone looking for something elegant and out of the ordinary in the garden.
