Aeonium Arboreum 'Zwartkop'

• Originally from the Canary Islands, this succulent grows as a tree-like shrub with distinctive dark burgundy to black rosettes.
• The name 'Zwartkop' means 'black head' in Dutch, referring to the dramatic dark colouring that intensifies in bright light.
• Unlike most succulents, it grows actively in winter and goes dormant in summer heat, making it perfect for cool-season interest.
• Mature plants can reach 1-2 metres tall and produce striking yellow flower spikes, though flowering signals the end of that rosette's life.
• Highly prized by collectors for its architectural form and dramatic colour that provides year-round structure in gardens.

• Water weekly during winter growing season, checking soil moisture first - allow top 5cm to dry between waterings. Reduce to monthly in summer.
• Position in bright, indirect light or morning sun with afternoon protection from harsh Australian sun. Indoor plants need the brightest available spot.
• Use premium succulent potting mix with excellent drainage, adding extra perlite if needed. Never use regular potting soil.
• Feed monthly with diluted liquid fertiliser during winter growing season only - avoid fertilising in summer dormancy.
• Remove spent flower spikes and dead rosettes to encourage new growth from the base and maintain plant health.
• Bring potted plants under cover when temperatures drop below 5°C to prevent frost damage.

• Provide bright, filtered light or morning sun with afternoon shade in hot Australian climates. Too much harsh sun causes leaf burn.
• Water deeply but infrequently during winter growing season, allowing soil to dry between waterings. Reduce watering significantly in summer dormancy.
• Plant in well-draining succulent mix with added perlite or pumice. Heavy clay soils will cause root rot.
• Protect from temperatures below 5°C as frost will damage the plant. Bring potted plants under cover in winter.
• Active growth occurs in cooler months - this is when to fertilise and propagate from offsets.

• Overwatering causes black, mushy stems and root rot - reduce watering immediately and improve drainage. Allow soil to dry completely between waterings.
• Aphids and mealybugs target new growth - spray with insecticidal soap or neem oil. Check regularly under leaves and in stem crevices.
• Sunburn creates brown patches on leaves when moved suddenly to bright light. Gradually acclimatise plants over 2-3 weeks.
• Stem collapse occurs from poor drainage in winter - ensure pots have drainage holes and use gritty succulent mix.
