Gynura aurantiaca, commonly known as purple passion plant or velvet plant, is a striking perennial admired for its vibrant, fuzzy foliage. This Gynura species features oval-shaped, serrated leaves covered in fine, soft purple hairs that give the plant a velvety texture and an iridescent glow when light catches them. It makes a popular choice for adding a touch of bold colour and tactile interest to indoor plant collections in the UK. It is a member of the Asteraceae family.
The genus name Gynura comes from Greek words, referring to the protruding styles of its flowers. Aurantiaca is a Latin word meaning "orange," referring to the colour of its small, daisy-like flowers.
Light: Gynura aurantiaca thrives in bright, indirect light. Strong, direct sunlight can harm its leaves, potentially causing burning or a dulling of the vibrant purple colour. Insufficient light may result in stretched growth and less intense purple hues. A position near a window with filtered light in a typical UK home is ideal.
Water: Keep the potting mix consistently damp but not saturated. Allow the upper inch of the soil to dry between waterings. Ensure the pot drains exceptionally well to prevent root problems, which can be an issue, especially in the UK's climate. Reduce watering in autumn and winter when the plant's growth naturally slows.
Soil: A well-draining potting mix is essential. A standard houseplant compost, possibly mixed with perlite to improve aeration, is often recommended.
Fertilising: Use a diluted liquid fertiliser every two to four weeks during the active growing period in spring and summer. Reduce or stop fertilising during the autumn and winter months.
Temperature: This plant prefers warm temperatures, ideally between 18°C and 24°C. It is not tolerant of frost and should be shielded from cold draughts and sudden temperature changes, which can occur indoors, particularly during colder UK months.
Humidity: Gynura aurantiaca appreciates moderate to higher humidity levels. Consider placing the plant on a pebble tray with water or grouping it with other plants to maintain optimal conditions, especially during drier indoor periods in the UK. Avoid getting water directly on the fuzzy leaves too frequently, as this can sometimes lead to spotting or fungal issues.
Growth Habit: It typically exhibits a bushy, upright growth habit, but its stems can trail as they mature. Regular pinching of the growing tips helps maintain a more compact and bushy shape. Small orange flowers may appear, but these are often removed due to their sometimes unpleasant scent.
Toxicity: Gynura aurantiaca is generally considered non-toxic to humans.
