The “white candles plant” (Pachystachys lutea) is a captivating tropical evergreen shrub native to Peru, also known as the Golden Shrimp Plant or Lollipop Plant. Its name comes from the upright, showy inflorescences with overlapping bright yellow bracts, from which slender, two-lipped white flowers emerge. Its unique display makes it a popular ornamental choice for gardens and as a houseplant.
White Candles Plant Care
Light Needs
The white candles plant thrives in bright, indirect light, mimicking its natural habitat. An east or south-facing window indoors, providing filtered sunlight, is ideal. Too much direct sun scorches leaves; insufficient light causes leggy growth and fewer flowers. Supplemental grow lights can promote better blooming if natural light is limited.
Watering
The white candles plant needs consistent moisture during its active growing season (spring-fall). Keep soil evenly moist, but not waterlogged, to prevent root rot. Water thoroughly when the top 1-2 inches of soil feel dry. During cooler winter months, reduce watering frequency; allow soil to dry slightly more between waterings as growth slows.
Soil Requirements
A well-draining potting mix rich in organic matter is ideal for Pachystachys lutea. A blend of peat moss, perlite, and compost provides drainage and retains moisture. The plant prefers a slightly acidic soil pH (6.0-7.0). Ensure the pot has adequate drainage holes to prevent water accumulation and maintain healthy roots.
Temperature and Humidity
Being tropical, Pachystachys lutea prefers warm conditions (65-80°F / 18-27°C). It is cold-sensitive; protect from temperatures below 50-55°F (10-13°C) to prevent stunted growth or leaf drop. High humidity (60-70%) is also beneficial. Indoors, increase humidity by placing the pot on a wet pebble tray, using a humidifier, or grouping plants.
Fertilizing
During the active growing season (spring to fall), regular fertilization benefits the white candles plant. Apply a balanced, water-soluble fertilizer (e.g., 10-10-10 or 20-20-20) every 2-4 weeks to support growth and blooming. A high-phosphorus fertilizer can also stimulate flowering. Avoid over-fertilizing, which leads to excessive foliage at the expense of flowers; reduce or cease fertilization during winter dormancy.
Pruning for Health and Shape
Regular pruning maintains the white candles plant’s compact form and encourages prolific flowering. Pinching back growing tips promotes bushier growth and prevents legginess. Deadheading spent flower spikes encourages new blooms and tidies the plant. Major pruning for shaping or size reduction is best done in early spring, before the main growing season.
Propagating White Candles Plant
Propagating the white candles plant is readily achieved through stem cuttings. Take cuttings during spring or early summer when the plant is actively growing. Select healthy, non-flowering stems 4-6 inches long, cutting just below a leaf node. Remove lower leaves; optionally, dip the cut end in rooting hormone for better success.
Cuttings root in water or a well-draining potting mix. For water rooting, submerge 2-3 inches of stem (leaves above water), changing water every 5-7 days. For soil rooting, insert cuttings into moist potting mix, burying at least two nodes. Covering the pot with a clear plastic bag or dome creates a humid environment for rooting. Roots typically develop within 2-6 weeks, then acclimate new plants to normal conditions.
Addressing Common Plant Problems
The robust white candles plant can face common issues. Yellowing leaves often indicate overwatering or poor drainage, leading to root rot. Adjusting watering habits to allow soil to dry slightly between waterings and ensuring proper drainage can resolve this. Wilting signals either underwatering or severe overwatering; check soil moisture to diagnose the cause.
Lack of blooms often indicates insufficient light or nutrient deficiencies. Move the plant to a brighter location or initiate regular fertilization during the growing season to encourage flowering. Common pests include spider mites, aphids, and whiteflies, especially on indoor plants. Manage these by increasing humidity, regular misting, or treating with insecticidal soap or neem oil. Leggy growth, characterized by sparse foliage, results from inadequate light or lack of regular pruning.
