The Anthurium Magnificum is one of my favorite anthuriums because of their large beautiful and striking leaves. They are dark green heart shaped with contrasting white crystal veins creating a pattern that truly makes this Anthurium Magnificent. Its soft leaves have a velvety like feel, with the under leaf a more subtle and pale green color that sparkles when the light hits it.
Lighting: Like most anthuriums, they are sensitive to light and heat. The ideal growing conditions for most Anthuriums is bright indirect or filtered light, in warm temperature of 25C or 77F. You don’t want to have the Anthurium in temperatures below 15C or 55F. I usually have mine about 10 feet away from my large south facing window to ensure they are not over exposed by the warm and bright light that I typically get in the summer.
Watering: I water my Anthuriums, when the mixtures is dry, and the pot is light in weight. Because my Anthuriums are in a very airy type of medium or mixture, I do water it more frequently than my other houseplants that is in my regular go to mixture. It’s important to not over water this plant, but also do not allow the mixture to dry out completely between watering. The medium and mixture will play a role in how much and/or how often to water your Anthuriums.
Medium Mixture: For most of my adult anthuriums like my Clarinervium and Dorayaki, I have them in a mixture with equal parts of orchid bark, coco husk, perlite, pumice and potting mix with a pinch of peat moss. Anthuriums thrive better in a very airy and light mixture with high nutrients. Some of my juvenile Anthuriums like the Silver Blush, Forgettii, and Anthurium Waracquenum are planted in sphagnum moss. I do like the sphagnum moss because it provides the moisture and humidity to the roots while providing an airy substrate to allow oxygen flow preventing the roots from getting root rot.
Do they need high humidity?
Anthuriums ideal growing condition is a tropical humid environment. It’s recommended that you provide good humidity and good air flow. While some specifies like the Waracqueanum require high humidity levels of 70%+, others can tolerate lower and average humidity levels of 30%, like the Clarinervium and Forgettii.
Can they thrive outside a greenhouse?
Yes, they can. Greenhouse is good for creating and maintaining high humid environment which is ideal and recommended for most Anthuriums. However, some anthuriums like a Clarinervium can be kept out of a greenhouse as long as they’ve been properly acclimated, and their location has some humidity either by using a humidifier, the old pebble and tray trick or constantly misting the area around your Anthuriums.
What’s a beginner type of Anthurium?
If you’re wanting to get an Anthurium and you’re a beginner when it comes to houseplants. I would recommend getting yourself one of those flamingo type of Anthuriums that you can find at your local grocery or garden shop. They’re mostly known for their blooms rather than their foliage. This will give you good practice on their basic care needs and get you familiar with their structure. They are also more cost effective, so if you happen to kill one it won’t hurt as much. However, if you are wanting one of these more exotic looking Anthuriums, then I think a Clarinervium is good for beginners, they don’t seem to be as fussy and can thrive outside a greenhouse in regular room temperature and humidity.
Here's a recent YouTube video of my Anthurium collections . I also share my experience so far on how I care for mine and propagated for the first time a baby Anthurium Clarinervium.
