Black Coral Elephant Ear (Colocasia esculenta 'Black Coral')
Black Coral Elephant Ear is a dramatic tropical foliage plant valued for its glossy black leaves, blue-toned veining, and bold warm-season presence. Its large, heart-shaped foliage brings deep color and strong contrast to patios, poolside plantings, large containers, moist garden beds, and tropical-style landscapes. This clumping elephant ear offers a polished, reflective look that stands out without relying on flowers for impact. With warmth, rich soil, steady moisture, and sun to partial shade, Black Coral Elephant Ear adds depth, texture, and tropical character to indoor and outdoor displays.
Distinctive Features
Black Coral Elephant Ear produces large, glossy leaves in deep purple-black to near-black tones, often with blue to blue-green veining that becomes more noticeable as the foliage matures. The leaves have a smooth, reflective surface that gives the plant a sleek look compared with more matte dark-leaved selections. It forms a strong upright to spreading clump that can fill out quickly during warm weather when provided with moisture, fertility, and heat. Flowers may appear occasionally as a spathe and spadix, but this plant is grown primarily for its dark foliage, tropical texture, and high-impact color.
Growing Conditions
- Sun: Grows best in full sun to partial shade, with brighter light often supporting darker foliage color when moisture is consistent.
- Soil: Prefers fertile, humusy, organically rich soil that stays consistently moist while still supporting healthy root growth.
- Water: Performs best with medium to wet soil and should not be allowed to dry out completely during active warm-season growth.
- USDA Zones: Hardy outdoors in USDA Zones 7 to 12 in protected conditions, while colder climates should treat it as a seasonal container plant or overwinter the tubers indoors.
- Mature Size: Typically reaches about 3 to 4 feet tall and 2 to 3 feet wide in favorable outdoor conditions, with larger size possible in warm, well-watered sites.
- Habit: Forms an upright to spreading clump with large dark leaves rising from the base on sturdy petioles.
Ideal Uses
- Focal Point: Use as a glossy dark-foliage focal point in large containers, patios, poolside plantings, courtyard beds, tropical-style landscapes, or moist garden areas.
- Container Planting: Grow in a large decorative pot where its black foliage can provide strong contrast and be moved or protected before cold weather.
- Moist Garden: Plant in consistently moist beds, rain gardens, or pond-edge settings where its tolerance for wet soil can support strong growth.
- Tropical Garden: Pair with cannas, bananas, caladiums, gingers, coleus, and chartreuse foliage plants to create a lush warm-season display.
- Mixed Border: Use in large mixed beds where its dark glossy leaves can add depth, contrast, and bold texture behind lower plants.
Low Maintenance Care
- Watering: Water regularly during active growth to keep the soil consistently moist, especially in containers and hot summer weather.
- Mulching: Apply mulch around outdoor plants to conserve moisture, moderate soil temperature, and reduce weed competition.
- Fertilizing: Feed during the active growing season with a balanced fertilizer to support large foliage and vigorous growth.
- Wind Protection: Site in a sheltered location because strong wind can tear or damage the large ornamental leaves.
- Overwintering: Lift and store tubers or move containers indoors before frost in climates where the plant is not reliably hardy.
- Leaf Cleanup: Remove yellowing, torn, or frost-damaged leaves as needed to keep the plant looking clean and encourage fresh growth.
Why Choose Black Coral Elephant Ear?
- Glossy Black Foliage: Displays large deep purple-black to near-black leaves with a sleek reflective surface for strong landscape contrast.
- Blue-Toned Veining: Adds extra color depth with blue to blue-green veining that enhances the dark foliage.
- Moisture Tolerance: Performs well in medium to wet soils, making it useful near ponds, rain gardens, and water features.
- Fast Warm-Season Growth: Responds quickly to heat, water, and fertility with lush foliage during the growing season.
- Tropical Impact: Brings bold scale, dark color, and glossy texture to patios, pool areas, large beds, moist gardens, and seasonal displays.
Black Coral Elephant Ear is an excellent choice for gardeners who want dark foliage, tropical texture, and strong seasonal impact. Its glossy black leaves, blue-toned veining, clumping habit, and love of moisture make it a standout plant for containers, patios, pond edges, and dramatic warm-season landscape designs.

Fantastic speaker plug at a great price!
Size: 5 Pack, Pattern Name: Banana Plugs
This is a product that gets the job done effectively, and at a good price. Banana plugs are used to clean up speaker wire - you can generally screw in speaker wire, but banana plugs provide a nice interface that allows you to plug in and remove speaker wire as needed.
These closed plugs do a good job terminating / hiding the wire. They fit very well into various components and amps that I own.
INSTRUCTIONS to install / use them:
* Remove around 1" - 2" of the white casing to expose the red and white individual speaker wires
* Strip each wire so ~1/2" metal is showing
* Make sure the plug end is screwed in tightly (this does not need to come out)
* Unscrew the base of the plug from the other end
* WithOUT twisting the metal wiring, insert the wire (match wire color with plug color; start with either one) from the bottom of the plug until the metal sticks out the top
* Have ~1/4" metal hanging past the plug
* take the wiring and drape it down the sides of the plug (just the smooth side, do NOT cover any of the screw threading or it will be very hard to close it)
* Spread the draped wiring around the plug as evenly as possible (makes it easier to screw in later)
* Screw the two ends of the plug back together (the side with the draped wiring will go inside the plug)
* If you get stuck while screwing it back in, unscrew and adjust the wiring
* Repeat for the other side, and you're done!

pretty good banana plugs
Size: 5 Pack, Pattern Name: Banana Plugs
i bought these over 6 months ago and i just installed them to the front left and right floor standing speakers - sony ssf-7000 i have them for over 10 years hooked up to a yamaha 7.1 AVR.
alot of people have had trouble installing this - one single banana plug comes in 3 parts - the bottom and top (the banana plug tip) can be unscrewed.
what i did was tightened the top first (top being the tip of the banana plug) then unscrew the bottom off completely - make sure you have like 3/4" - 1" (depending on your gauge of wire) of exposed speaker wire that is straight - then thread it through the hole at the bottom up - i then rolled the exposed 3/4 - 1" exposed copper wiring into a ball that is bigger than the hole of the banana plug bottom piece so the wire doesn't fall back through where it came from. then i screwed on the top and middle piece back with the bottom piece - tightening it a bit so i know there's good contact. also make sure the tip is screwed in all the way as well as a double check. what you don't want to do is have the copper wire touch the threaded part of the bottom piece - the wire will cut off from the screwing action.
i plugged it into my sony speakers and it wasn't a real snug fit - a bit too loose to feel secure - it didn't seem to go all the way in - but it fit fairly well in my receiver. my intention was to use these banana plugs with my 2 channel set up but i decided to go pre-constructed mediabridge 12 AWG speaker cable instead - those fit my 2 channel set up on my receiver and elacs really snug and secure.
i tested it and it works fine. i didn't hear any loss of signal or any extraneous noise. none of my (14 awg?) wiring fell through the bottom and it sounds good. so no complaints there.
i bought 5 pairs - but i find that it is an odd number to include a package - even numbered pairs would be better.
anyway they seem constructed well - easy enough to install and they do work.
thanks for reading

High quality and robust
Size: 12 Pairs, Pattern Name: Banana Plugs
Easily the best plugs I've found at a reasonable price. Solid feeling with good quality and they look good with easy to see red/black labeling. The tips tend to unscrew too easily, but this is a non-issue when they are in use, just something you have to be careful not to lose when assembling. It's a bit tricky to spread the wire out evenly at the exact right length. If screwing the plug together is hard at all, go back and shorten how much wire you bend over the lip.

Solid banana clips
Size: 5 Pack, Pattern Name: Banana Plugs
Ah yes, I used these solid banana plugs to convert my wires. It’s pretty easy to set up once the wire housing has been stripped and really cleans things up nicely. I haven’t had any discernable hissing, noise problems, or connection issues.

Get the right wire guage
Size: 1 Count (Pack of 1), Pattern Name: Banana Plugs
I rate the banana plugs themselves 4 stars. They are everything I expected and work as advertised. It's the experience of assembly that I rate three stars. The way these work is -- you strip off the outer insullation of your wire and separate the two leads (positive and negative). Then you strip some length of insulation off the end of one of your leads, you unscrew the banana plug so that it separates into its respective base (lower) and contact (upper) halves, you slip the wire up through the base, you flare the copper strands of the wire and fold the individual strands over the very top of the base (about 1/16 of an inch) (taking care not to extend the strands over the threaded barrel of the base), then you screw the upper contact onto the lower base and voila, banana plug / wire assembly. It's not as complicated as it sounds. Go to the Monoprice website and watch their excellent instructional video.
Here's the thing though. While the assembly is not complicated, it is tricky, and if you don't get your proportions right the first or second or third time, you'll have to do it over. Fist of all, if your wire guage is relatively thin, like my 16-guage speaker wire, you'll find that the entire wire, insullation and all, will slip right through the base of the plug without butting up against the bottom of the base. If this is the case, then the wire is left to sort of flop around inside the plug and that has a kind of unfinished, amateur look and feel to it, whereas if the wire butts up against the bottom of the base, it has a solid, one-piece professional look. So, to my mind, there's a sweet-spot for wire guage that works best with this plug -- not too thin and not too thick. And since Monoprice has debunked the thicker-is-better myth (the quality of the copper is the real determinant), then you should feel free to get the wire guage that fits the plug.
Next -- and here's where it gets tricky -- once your copper extends beyond the top of the base, you'll need to limit this extension to about a sixteenth (no greatrer than a fourth) of an inch. Then you very delicately flare out the individual strands, in a 360- degree arc, and fold the strands over the top of the base. This takes a fair degree of manual dexterity, especially if the wire is "floating" inside the base and its travel is not stopped where the insullation meets the base. You'll have to hold the wire and base steady in the fingers of one hand, then flare out the wire strands with either your fingers or a suitable object (the working end of a ball-point pen worked for me) with the other hand. This one-sixteenth measure is important. If you extend wire strands beyond the top and over the threads of the base, you'll find that screwing the contact end onto the base is impossible and you'll need to start over. One or two strands is OK and almost unavoidable. In that case the screwing will catch but if you take a pair of pliers to it you can muscle through. By the way, you can avoid the whole mess by getting the open-screw type, which I'm sure will work just as well without any of the hassle of assembly.
Like anything else, if you do it a few times to make the mistakes and learn the tricks, then it will become second nature, and if you've already done that, then my review might seem overly fussy. In that case feel free to leave comments to help other readers.
