About Strap-Leaf Anthurium

Anthurium wendlingeri · also called Strap-leaf anthurium, Wendling's anthurium · houseplant

The strap-leaf anthurium (Anthurium wendlingeri) is a pendant epiphytic aroid from Central American cloud forests, prized for long, corrugated, cascading strap leaves. It needs bright indirect light, a chunky airy mix kept evenly moist, and high humidity above 60 percent. Like all anthuriums it is toxic to cats and dogs.

Comfort temperature: 18-27°C

Watch for — Root rot: Caused by a dense, waterlogged mix or overwatering, often with Phytophthora or Pythium. Use a chunky, free-draining epiphyte mix and let the surface dry slightly between waterings.

The exact light strap-leaf anthurium needs

Strap-Leaf Anthurium wants bright, indirect light — lots of it, but filtered or off to the side, not the harsh midday sun that scorches its leaves.

Put a number on it — this is what a meter (or a free phone light-meter app) should read where strap-leaf anthurium sits:

In plain terms, A few feet back from a south or west window, or right beside a bright east window. A sheer curtain over a sunny window is close to perfect: lots of light, no direct beam burning the leaves. Hours of unfiltered midday sun directly on the leaves (scorch), and dim back-of-room corners (slow decline). It is the both-extremes plant.

Signs strap-leaf anthurium is getting too much light

The most exposed leaves show it first. For strap-leaf anthurium specifically, watch for:

Light damage does not heal — a scorched leaf stays scorched — so the fix is to move strap-leaf anthurium out of the harsh light rather than wait for it to recover.

Signs strap-leaf anthurium is not getting enough light

Too little light is slower and sneakier than too much. The classic tell is etiolation: the plant stretches and pales as it reaches for a window. For strap-leaf anthurium, look for:

If strap-leaf anthurium is stretched, leggy and pale, our guide to leggy, stretched plants covers how to fix it and whether it can be pruned back into shape. Confusing "bright indirect" with "any bright room". Strap-Leaf Anthurium needs to actually see a lot of sky — a sunless north wall or a deep corner is far too dim, even if the room feels light to you. The opposite mistake is parking it in raw afternoon sun, which scorches it within days.

Where to put strap-leaf anthurium: the best window and room

The sweet spot for strap-leaf anthurium is the band of bright light just out of the direct beam: a metre back from a south/west window, immediately beside an east window, or behind a sheer curtain on a sunny window. Rooms with a single small north window are usually too dark for it to do well long-term; a bright bathroom or a plant stand near (not in) a sunny window suits it far better.

  1. Find a bright but shielded spot. For strap-leaf anthurium, the ideal is a metre back from a sunny window, beside an east window, or behind a sheer curtain — bright, but no direct beam on the leaves.
  2. Check for the shadow test. Hold a hand where the plant sits: a soft, fuzzy shadow means bright indirect (good); a hard, sharp shadow means direct sun (scorch risk); barely any shadow means too dim.
  3. Shield from harsh afternoon sun. If the only bright window gets fierce afternoon sun, add a sheer curtain or step strap-leaf anthurium back a couple of feet rather than into a dark corner.
  4. Re-place it each season. Move strap-leaf anthurium closer to the glass for the dim winter months and back again in spring — same spot, very different light.

Does strap-leaf anthurium need a grow light?

Strap-Leaf Anthurium responds well to a grow light if your home is dim: a mid-power full-spectrum LED about 30–45 cm above the plant, run 10–12 hours a day, comfortably stands in for the bright window it is missing — a useful fix for north-facing flats.

The seasonal light shift (why winter changes everything)

Winter light is a fraction of summer's, even at the same window. A strap-leaf anthurium that is perfect a metre back from the glass in July may need to move right up to the window from November to February. The bonus: weak winter sun rarely scorches, so a spot that is too harsh in summer can become ideal in winter — and vice versa.

Light and watering are linked: a plant in weaker winter light photosynthesises and drinks far less, so the same routine that worked in summer can rot it. See how often to water strap-leaf anthurium for the season-by-season schedule that pairs with this light plan.

Strap-Leaf Anthurium light requirements — frequently asked questions

How much light does strap-leaf anthurium need?

Strap-Leaf Anthurium needs Roughly 400–800 fc — genuinely bright, but indirect. Around 4,000–8,000 lux: bright shade, the light a metre or so off a sunny window. A few feet back from a south or west window, or right beside a bright east window. A sheer curtain over a sunny window is close to perfect: lots of light, no direct beam burning the leaves.

Can strap-leaf anthurium survive in low light?

No, not really. Strap-Leaf Anthurium is a bright-light plant — in low light it etiolates: it stretches, pales, weakens and slows right down. It will not instantly die, but it steadily declines and never looks its best.

What are the signs strap-leaf anthurium is getting too much light?

Bleached, faded patches and dry, brown, papery scorch where direct sun strikes strap-leaf anthurium — the burn does not recover, so move it rather than wait. Crispy leaf edges and tips on the most sun-exposed side while shaded leaves stay green. Curling or cupping leaves angling away from an over-bright window. Confusing "bright indirect" with "any bright room". Strap-Leaf Anthurium needs to actually see a lot of sky — a sunless north wall or a deep corner is far too dim, even if the room feels light to you. The opposite mistake is parking it in raw afternoon sun, which scorches it within days.

What are the signs strap-leaf anthurium is not getting enough light?

New leaves come in small, pale and widely spaced as strap-leaf anthurium etiolates, stretching toward the light. Leggy, drawn-out growth, loss of any variegation or rich colour, and a thin, reaching habit. Lower leaves yellow and drop while the plant prioritises the few that get light. If you see this, move strap-leaf anthurium closer to the light or add a grow light — and check our guide on leggy, stretched plants.

Does strap-leaf anthurium need a grow light?

Strap-Leaf Anthurium responds well to a grow light if your home is dim: a mid-power full-spectrum LED about 30–45 cm above the plant, run 10–12 hours a day, comfortably stands in for the bright window it is missing — a useful fix for north-facing flats.
