Anthurium Warocqueanum Care

ABOUT 
Anthurium Warocqueanum, also known as the Queen Anthurium, is an epiphytic aroid native to Colombia. It has large, suede-like, leaves that are deep emerald green in color with an intricate pattern of bright light green veins. The leaves can grow 4-6 feet long.

FAMILY 
Araceae

LIGHT REQUIREMENTS

I would consider these guys moderate to semi-shade. If they're in a spot too dark, their growth will slow and they'll get a bit leggy, but if they're in a spot too bright they'll suffer light bleaching (lighter color, speckled appearance.) I would aim for the middle ground and adjust if you notice it going one way or the other.

TEMP / HUMIDITY 
65 - 75° F (18.5 - 24° C) / 60% + Humidity.
Queen Anthurium actually prefer temps a bit on the cooler side compared to a lot of other tropical plants. High humidity is definitely a plus (my shop plants are grown at around 80%) but they CAN be acclimated down to lower, more household-ish, humidity, though in those conditions I would expect slower growth. When acclimating, I usually recommend bring plants down 10% at a time to avoid shocking them.

WATERING 

Keep soil evenly moist but not waterlogged. These gals are actually pretty sensitive to both over and under watering. If you're giving it either too much or not enough you'll start to notice small yellow or brown spots around the leaf margins. I'd recommend keeping a close eye until you get a sense of her own, annoyingly specific, watering preferences.

GROW MEDIA 
Very chunky mix - Chunkier the better, topped with moss. (The one I personally use has almost no dense or "wet" ingredients, I think I use about 1 part in 10 of coco coir, the rest is all bark, husks, pumice and etc.)

They also do well in Pon, I actually don't recommend LECA... while I've found they tolerate it well (and even thrive in it) when they're young, they start to have issues with it as they size up. Large Queen just don't seem to like their feet SITTING in water, which is harder to avoid in LECA than in Pon. (Although in fairness, a lot of that might be down to the pots I use for the different media than the media itself.)

GROWTH RATE 

Growth rate for these guys really depends a lot on your humidity. They can get on fairly well in normal household conditions (if properly acclimated) but their growth will be slower than in a higher humidity environment. 

EASE OF PROPAGATION 
On a scale of 1 (easiest) to 5 (most difficult) I'd say... 2? Though again, it depends on your level of experience and supplies you have on hand. I'd suggest a prop box / cloche / humidity dome (high humidity is the goal) with a net pot and chunky perlite. 

TOXICITY 
Toxic to pets and humans.

ADDITIONAL INFO 
I've found Warocqueanums to be pretty sensitive to fertilizers. If using a standard NPK I'd recommend feeding less frequently at a lower concentration ("weekly, weakly") to avoid issues.
