UNITED STATES—Plants can inhabit nearly every climate on Earth. They live in hot and dry deserts, cold arctic regions, rainforests and just about everywhere in between. Plants seem to have it all figured out. Some even know how to live in our homes as houseplants, although they probably did not plan it that way. Most houseplants are tropical plants that are naturally endemic to tropical ecosystems.
It is actually their tropical heritage that makes them more comfortable in our homes. Tropical climates tend to be conducive to proliferation of all kinds of plants. Those that want to live there must be competitive. Trees compete by growing faster and taller than other trees. Vines compete by climbing the trees. Understory plants that live under taller plants compete by needing less sunlight.
It is these understory plants that do not mind the shade of our homes. Even those that like bright ambient light might never expect to get direct sun exposure. The various ficus trees that might naturally grow tall enough to reach the top of a forest canopy in the wild are still understory plants while young. Because they know how to use resources efficiently, tropical plants do well in pots.
However, these advantages are not so useful out in the garden. Tolerance to partial shade also means that some tropical understory plants need to be sheltered. If too exposed, foliage can get roasted by sunlight or arid wind. (Most tropical climates are more humid than local climates are.) Complaisant roots do not disperse well enough to sustain lush foliage without regular watering.
Ironically, roots of the various ficus trees are very aggressive because they to not disperse deeply, but instead spread out at the surface of the soil where they grow into exposed root buttresses.
The most familiar weakness of tropical plants is their susceptibility to frost. Even though it does not get very cold here, it gets cool enough in winter to offend plants that would never experience cool weather in the wild. Actual frost can severely damage foliage, and can even kill some tropical plants.
Just like potted chyrsanthemums, azaleas, hydrangeas and poinsettias, potted specimens of Guzmania magnifica are popularly purchased while beginning to bloom, enjoyed as house plants through a long bloom cycle, but then discarded as bloom eventually deteriorates. They are rarely allowed to produce new pups that can be divided and grown into fresh new plants to bloom later.
The bright yellow, orange, red or pink bloom stalks, as well as their rich green basal foliage, are so glossy that they seem to be plastic. The colorful parts of the blooms are pointy strap shaped bracts that arch outward from upright stalks. The leaves below have the same shape, but are longer, and more densely arranged in neat rosettes. Tiny flowers are mostly obscured by the bracts.
Guzmania magnifica, likes bright ambient sunlight without direct sun exposure, and can tolerate significant shade, especially if grown for only a few months while blooming. They seem to like misting, but probably do not need it. They should be watered only weekly to every two weeks, when the surface of the soil seems to be getting dry. Too much fertilizer might scorch the foliage.
