About Anthurium andraeanum 'Purple Victory'
Anthurium andraeanum 'Purple Victory' · also called Purple Victory anthurium · tropical
Anthurium 'Purple Victory' is a hybrid flamingo flower prized for glossy deep-purple to wine-burgundy spathes held above heart-shaped leathery leaves. It blooms almost year-round indoors when given bright indirect light, an airy chunky mix, warmth and steady moisture. An epiphytic aroid, it dislikes soggy roots and cold drafts but rewards consistency with repeat flowering.
Growth habit: Compact, clumping evergreen epiphyte with an upright-to-arching rosette of leathery heart-shaped leaves and long-lasting coloured spathes on tall stems. Slow to moderate grower; produces offsets at the base over time.
Watch for — Brown leaf tips and edges: Usually low humidity or salt/fluoride buildup from tap water. Raise humidity above 60% and water with rain or filtered water, flushing the pot periodically.
What fertiliser anthurium andraeanum 'purple victory' actually wants — and why
Anthurium andraeanum 'Purple Victory' is an easy, light foliage feeder — a half-strength balanced liquid feed through the growing months keeps it green without forcing weak, sappy growth.
A balanced general houseplant feed (roughly even N-P-K) is exactly right — it is grown for foliage, so steady, moderate nitrogen for healthy leaves is the goal, not a bloom or root formula.
For the language behind the three numbers on the bottle — what nitrogen, phosphorus and potassium each do — see the NPK ratio explained entry. The short version for anthurium andraeanum 'purple victory': match the feed to the job the plant is doing right now, not to a generic “plant food” on the shelf.
How often to feed anthurium andraeanum 'purple victory', and which months
Feeding only earns its keep while the plant is in active growth and can use the nutrients — pour feed into a dormant or low-light plant and it simply builds up as root-burning salt. For anthurium andraeanum 'purple victory':
Feed every 4-6 weeks in spring and summer with a balanced or bloom-leaning houseplant fertiliser at half strength; a formula slightly higher in phosphorus supports flowering. Pause feeding in winter. Flush the pot occasionally to clear salt buildup, which causes leaf-tip burn. Treat that as every 4-6 weeks between spring through early autumn (roughly March to September); ease off in autumn and stop entirely in the low light of winter.
The dormant-season rule matters more than the exact interval: skip feeding entirely when anthurium andraeanum 'purple victory' is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.
What strength to mix for anthurium andraeanum 'purple victory'
Half strength is the safe default for anthurium andraeanum 'purple victory' — houseplant feeds are formulated strong, and the diluted dose is gentler on the roots while still ample for foliage.
Feeding always goes onto already-damp soil, never dry roots — water anthurium andraeanum 'purple victory' first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the anthurium andraeanum 'purple victory' watering schedule.
Signs you are over-feeding anthurium andraeanum 'purple victory'
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for anthurium andraeanum 'purple victory':
- Brown, crispy leaf tips and edges with no sign of underwatering.
- A white, crusty salt deposit on the soil surface or pot rim.
- Weak, pale, stretched new growth that flops.
- Lower leaves yellow and drop while the soil is correctly watered.
Signs you are under-feeding anthurium andraeanum 'purple victory'
- Uniformly pale or yellow-green leaves, oldest first.
- Noticeably small new leaves and stalled growth in good light and season.
- A generally tired, lacklustre look despite correct watering and light.
If the symptoms point at watering, light or roots rather than nutrition, the full anthurium andraeanum 'purple victory' care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of anthurium andraeanum 'purple victory' with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.
Organic vs synthetic feeds for anthurium andraeanum 'purple victory'
Organic options
A diluted seaweed or worm-casting feed, or fish emulsion if you can tolerate the smell indoors. UK: Westland or Baby Bio Organic, dilute seaweed; US: Espoma Indoor! or Neptune's Harvest fish & seaweed. Slow, gentle and hard to overdo.
Synthetic / liquid feeds
A general-purpose houseplant liquid at half strength — UK: Baby Bio, Westland Houseplant Feed or Phostrogen; US: Miracle-Gro Indoor Plant Food or Schultz. Convenient and fast-acting; the only risk is overdoing it.
Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.
