How to grow lantana
Overview
Lantana camara is a fast-growing, multi-stemmed shrub from tropical America, widely naturalised in Australia. It is grown for its dense, bushy habit and long-lasting clusters of small, brightly coloured flowers that attract butterflies. A key fact: many cultivated varieties are sterile, but some forms can become invasive in bushland, so always check local weed status before planting.
Varieties
- Lantana camara 'Radiation' — Vigorous, sterile variety with bright orange and yellow flowers; ideal for low-maintenance gardens.
- Lantana camara 'Miss Huff' — Hardy, cold-tolerant cultivar with pink and yellow blooms; suitable for temperate zones.
- Lantana camara 'Gold Mound' — Compact, mounding form with golden-yellow flowers; excellent for ground cover and containers.
Soil Preparation
Lantana prefers slightly acidic to neutral soil (pH 6.0–7.0) but tolerates a wide range. Improve drainage in heavy clay by adding coarse sand or planting on a mound. It thrives in poor to moderately fertile soils; avoid rich compost that can promote leggy growth.
Growing Guide
Plant lantana in full sun in well-drained soil; it thrives in hot, dry positions. Space plants 60–90 cm apart for a dense hedge or 1–1.5 m for individual specimens. Dig a hole twice the width of the root ball, backfill with native soil, and water in well. Avoid overwatering after establishment—deep, infrequent watering encourages a robust root system. In cooler zones, wait until after the last frost to plant out.
Care
Feed in early spring with a balanced slow-release fertiliser (e.g., 10-10-10). Prune hard after each major flowering flush to shape the plant and encourage dense growth; remove spent flower heads regularly to prolong blooming. In late winter, cut back up to one-third of old wood to rejuvenate.
Companion Planting
Lantana pairs well with other sun-loving, drought-tolerant plants such as bougainvillea, grevillea, and salvia. It also attracts butterflies, making it a good companion for nectar-rich species like pentas and verbena. Avoid planting near native bushland where it may escape and become weedy.
Common Pests & Risks
Whitefly can be problematic in dry spells; treat with a horticultural oil or insecticidal soap. Mites may cause stippling on leaves; increase humidity around the plant or apply a miticide if severe. Lantana is generally pest-resistant once established, but monitor for aphids on new growth.
Troubleshooting
Yellow leaves: overwatering or poor drainage—reduce watering and improve soil drainage. Brown leaf edges: salt burn from coastal exposure or fertiliser—flush soil with water and reduce fertiliser. Stunted growth: cold damage or root rot—protect from frost and ensure soil is well-drained. Leggy growth: too much shade or overfertilising—move to full sun and reduce nitrogen. Leaf drop: sudden temperature change or drought stress—acclimate gradually and water consistently.
