Description
You can easily grow Acroclinium (Helipterum) 'Blanche' from seed. This frost-tender perennial native to Australia, is cultivated as an annual in our climate for its striking summer flowering. This light and bushy plant, also called Rhodanthe, produces delicate white flowers with yellow centres, shaped like daisies with a papery texture, which illuminate flower beds and are perfect for making dried bouquets. It prefers sunny positions and light, well-drained soils, even dry ones, making it an ideal candidate for rockeries, dry gardens, or container cultivation. Sow Acroclinium under cover from February or directly in the ground from April, after the last frosts.
Acroclinium 'Blanche', also known by the botanical names Rhodanthe chlorocephala subsp. rosea, Helipterum roseum or Acroclinium roseum, is a frost-tender perennial from the Asteraceae family, cultivated as an annual in temperate climates. Native to southwestern Australia, particularly the coastal regions between Perth and Shark Bay, this plant thrives naturally in well-drained sandy soils, under a Mediterranean climate characterised by wet winters and dry summers. It forms an upright clump 30 to 50 cm in height, with fine, branched stems bearing linear, narrow, greyish-green leaves. The flower heads measure about 4 to 6 cm in diameter and feature papery, white bracts surrounding a yellow or black central disc, with no notable fragrance. Flowering occurs from June to September, attracting various pollinators. The fruits are dry, non-edible achenes, equipped with a feathery pappus that facilitates their dispersal by wind. The root system is clumping, adapted to light and well-drained soils. This plant is particularly prized for making dried bouquets, as the flowers retain their shape and colour after drying. Despite its many botanical reclassifications over time, it remains popular under the name 'Australian everlasting flower', a testament to its longevity as a dried flower.
Acroclinium 'Blanche' integrates gracefully into bright scenes. Its immaculate, paper-light flowers bloom above fine foliage, adding a touch of freshness to sunny borders. To accentuate this lightness, pair it with Nigella damascena 'Miss Jekyll', whose pale blue flowers and airy foliage create a subtle contrast. Limonium sinuatum 'QIS Apricot' introduces pastel hues and a complementary texture, while Bracteantha bracteata 'King Size Silvery Rose' offers warm tones and long-lasting flowering. Together, these plants create a harmonious picture, ideal for dry gardens, rockeries, or summer containers.

Planting and care
Sowing:
Sow Acroclinium Blanche seeds from March to early May on the surface of good quality seed compost. Germination takes 14 to 20 days at 18-25°C.
They can also be sown directly in situ in April, at a depth of 6mm, in moist, well-raked soil, spacing the seeds 25cm apart.
Transplant the young plants into trays or 8cm diameter pots and allow them to grow in cooler conditions. When well developed, acclimatise them to outdoor conditions for 10-15 days and plant them outside in May after all risk of frost has passed. Space plants 30cm apart. Choose a sunny location with well-drained soil.
Cultivation:
Very easy to grow, this plant requires no specific maintenance. It thrives in poor, light, perfectly drained soil, but requires plenty of sun to flourish. In pots, watering should be regular but not excessive throughout the growth and flowering period.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
