Diamond Head Elephant Ear (Colocasia esculenta 'Diamond Head')
Diamond Head Elephant Ear is a dramatic tropical foliage plant valued for its glossy dark leaves, ruffled texture, and bold warm-season presence. Its heart-shaped foliage develops rich chocolate, deep purple, to nearly black tones, giving containers, patios, poolside plantings, and moist garden beds strong contrast. This clumping elephant ear brings a polished, reflective look to the landscape without relying on flowers for impact. With warmth, rich soil, steady moisture, and sun to partial shade, Diamond Head Elephant Ear adds depth, texture, and tropical character to indoor and outdoor displays.
Distinctive Features
Diamond Head Elephant Ear produces thick, glossy, heart-shaped leaves with ruffled edges and dark chocolate to purple-black coloring. The foliage often points downward in classic Colocasia fashion, creating a bold, layered look as the plant fills out. It forms a strong clump that can gain impressive size during the growing season when provided with heat, fertility, and consistent moisture. Flowers may appear occasionally as a yellowish-green spathe and spadix, but this plant is grown primarily for its dark foliage, tropical texture, and glossy surface.
Growing Conditions
- Sun: Grows best in full sun to partial shade, with brighter light helping support 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 regular moisture during active growth and can tolerate moist to wet soil better than many ornamental foliage plants.
- USDA Zones: Hardy outdoors in USDA Zones 7b to 11 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 5 feet tall and 3 to 5 feet wide in favorable outdoor conditions, while container-grown plants may stay smaller.
- Habit: Forms a large upright to spreading clump with broad 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 dark reflective 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 love of moisture 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 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 Diamond Head Elephant Ear?
- Glossy Dark Foliage: Displays chocolate to purple-black leaves with a reflective surface for strong contrast in containers and garden beds.
- Ruffled Texture: Produces thick heart-shaped leaves with ruffled edges that add extra movement and depth to the planting.
- Moisture Tolerance: Performs well in consistently moist 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.
Diamond Head Elephant Ear is an excellent choice for gardeners who want dark foliage, tropical texture, and strong seasonal impact. Its glossy purple-black leaves, ruffled edges, clumping habit, and love of moisture make it a standout plant for containers, patios, pond edges, and dramatic warm-season landscape designs.

Everyone knows this is one of the absolute GOATS of Logitech Mice - get one before they're gone...
Style: M705
I've had many Logitech mice over the years I've really loved that were then discontinued. This is a long running mouse that pretty much ALL logitech users just love! And since it's long in the tooth, I'd recommend stocking up while you can. Here's some of the perks, but above all else, it feels so amazing!
1. It's a smallish, very light, simple mouse. I personally don't like the giant gaming mice. This has everything I need, including a scroll wheel you can click between smooth and ratcheted mode.
2. Uses 1 or 2 AA batteries - This gives it incredible battery life - many months at least. And when you do need to replace batteries, it's instant. I keep a pair in my backpack. So much more convenient than having to charge a rechargeable mouse, especially given rechargeable batteries slowly wear out.
3. Works like a dream on Macs with no drivers installed at all!
4. You can stash the wireless USB receiver dongle inside the mouse! Which is priceless.
Note that nowadays, I have an Apple Silicon Mac, I have to use a tiny adapter to plug the dongle into a USB-C port. But it's still tiny and convenient.
5. For me, Logitech still hasn't made anything better. I'd love to see a mouse almost like this with a USB-C receiver, but until then, it's as close as it gets to my perfect mouse. I have tons of these all over the place.

For the price, it's a very good wireless mouse. But it's not my MX Anywhere.
Style: M705
I have two first generation MX Anywhere Mice that have countless hours and probably thousands of "miles" on each of them. Didn't know what they were about until I'd owned the first one for a few months, which eventually led to my buying a second one. That second one was "refurbished" because it was purchased some time later (from Amazon), as by then the second generation had been released and I simply liked my first gen so much I wanted another. So why did I buy the M705 Marathon Mouse? Well, the MX I've used the most over the years turned out to be the refurbished one. Why? Luck of the draw? Don't really know, but because of the constant, daily use it began giving me problems with double clicking on the left button and occasionally on the right button. That's a lot of use! I looked at buying the latest MX Anywhere mouse, but didn't like the prices and couldn't be sure if they were as well made as my originals. So, I ordered the Marathon, which appeared to be a less expensive version of the MX. Well, unfortunately it's not. Compared to most other mice, the Marathon is fine; typical good Logitech ergonomics, tracking and getting the job done. But, park it next to my MXs and use them one after the other and you "feel" the difference. As old as my MXs are, they still feel more precise, tighter and more responsive than the Marathon. They also are a better fit for my hand; the Marathon is a larger mouse which for where I use it means it doesn't "fit" my work area as well. Also, Logitech claims you can "customize" the Marathon using their software, but it was a lot of work to actually find "that" software for the Marathon and once I did it simply did not work as well as the software/MX Anywhere combo I've used for so long. What the Marathon has going for it is it's price, it's still an RF (radio frequency) and not a Bluetooth mouse (I hate Bluetooth mice, totally different response curve), and it is "Logitech." So what does all of this mean? Well, I put the Marathon to work (yeah, no more unwanted double clicking!) and parked the refurbished MX. I then checked on Mouser Electronics, found the correct replacement switches for my MX ($0.80 each), ordered them, and upon arrival I replaced the old switches. It was an easy swap on the little MX circuit board (it did require some extensive tear-down), with the result of: My old MX is back in service! And what's to become of my Marathon? Well, it's a good mouse, so it has a new home out in my shop, as it replaced my Logitech wireless mouse for my Dell laptop I use out there. By the way, that Logitech is from the late 1990's (Win 98/Win XP period)! And I don't think that one will ever wear out!

Beware of the Top Button!!😁
Style: M705
A smooth but weighted feel on a mouse pad. I have mice that move with a much lighter touch, but this is great for the computer I use with my main TV screen. Beware of the top damnable button, the one just before the scroll wheel. It turns off the clicky graduations you wheel as you roll the scroll wheel with your fingertip. When used it unleashes a whirling dervish of a gremlin, your screen will continue to scroll after you want it to stop. Sometimes it will start on its own! Incantations, voodoo, chick bones, curses and magic wands have no effect. Yelling seems to make it worse. There is no other cure other than to push the top button from Hades again. Clicks from the two main buttons are easily audible but not obnoxious. The side buttons for screen forward & back work very well also. This is my second one of these, the first stopped moving smoothly on a pad, no amount of polishing seemed to help so I retired it.

Important Info for Connecting Replacement Mouse
Style: M705
I purchased the MK705 mouse to replace the same model that had simply worn out after over 13 years of faithful service. The MK700/710 Logitech keyboard is still going strong, albeit with a few worn keys.
I did however run into an issue when installing the new mouse. At first I left the old unifying receiver that came with the old mouse plugged into a usb port. I installed the batteries in the new mouse, turned it on, and found that it would not work. I figured it needed the new unifying receiver, so I turned off the keyboard and mouse and plugged the new receiver into the same USB port. The new mouse then worked but the keyboard would not. I couldn't figure out what was wrong, so I phoned Logitech support. The gentleman I spoke with walked me through the connection process, which was done on their website "logiwebconnect.com". Should you run into the same issue, the process is simple. You probably won't need any help from tech support, but if you do, they were easy to get in touch with.
