In this article, we will look at how we can grow and care for your Hemigraphis alternata at home.

They are herbaceous perennials and belong to the flowering plant family – Acanthaceae along with:

Purple Waffle Plant Care

Size and Growth

Purple Waffle Plant is a low-growing, sprawling forest floor plant with a prostrate, spreading growth habit. It may reach only a mature size of 8″ inches while spreading 18″ inches or more. 

Hemigraphis alternata feature 3″ to 6″ inches long oval leaves that are glossy, puckery, corrugated, and toothed. 

This tropical has beautiful oval leaves that are hairy and opposite with grayish-green metallic sheen tops and lighter green or purplish bottom surfaces. 

Excessive amounts of sun will prevent the leaves from developing their classic metallic sheen. 

Some cultivars have slightly different coloring. For example, the Snow White Waffle Plant has green leaves with large white markings and splashes of pink. 

On the other hand, the Belgian Waffle Plant has green leaves with cream-colored margins. 

Flowering and Fragrance

The bell-shaped blooms of Red Ivy are small, white, unscented, yet attractive, appearing in summer. However, the tiny white flowers are only secondary to the plant’s beautiful foliage.

They grow in clusters of inch-long racemes in the summertime. 

Plants indoors need ample bright, indirect sunlight to spur blooming.

Light and Temperature

Grow Red-Flame Ivy in full sun to part shade. Outdoors, full morning sun with protection from harsh noonday and afternoon sun will produce the best results. Avoid direct sunlight, as it can cause the leaf edges to scorch or the color to bleach. Direct sun can also result in the fading of the cool metallic sheen of the leaves. However, your Purple waffle plant may lose its rich purple color without enough light. A setting that provides consistently bright, indirect light will work well when kept as a houseplant. The plant can be placed directly in a north or east-facing window. If your only exposure is west or south-facing, place the plant a few feet away from the window. When you cannot access natural light, these plants thrive under artificial lights.Waffle Plant is winter hardy in USDA hardiness zones 10 and 11. In colder climates, the plant will die off after the first frost. 

Indoors, strive to maintain temperatures between 55° and 75° Fahrenheit.

Remember that they need high humidity conditions for healthy growth. If the humidity levels are low, you can increase them by misting or growing your plants in a pebble tray with water.

You can also maintain relatively high humidity levels (50% to 70%) through a humidifier.

Watering and Feeding

Keep the soil slightly moist by watering whenever the top quarter inch of soil becomes dry. However, don’t soak the soil, and never leave your plant standing in water, as this can lead to root rot. 

Fertilize once early in the spring and again in mid-summer. Excessive amounts of fertilizer will cause spotty leaves or white spots on leaves and leggy growth. 

Use a liquid fertilizer formulated for indoor plants. The NPK ratio should be 6-12-6. 

Using a slow-release 6-12-6 houseplant fertilizer will also provide the necessary nutrients, including phosphate, potash, and nitrogen, for healthy growth.

In the landscape, top dress/mulch with well-rotted compost very early in the springtime. The compost will provide nutrients on a slow, steady basis while helping maintain moisture in the soil surface. 

Add another layer of compost in mid-summer. Don’t fertilize in winter. 

Soil and Transplanting

This low-growing plant does best in fertile, moist soil with a great deal of humus content and a pH level of 6.1 to 6.9. 

Moist, well-drained soils will also work well for this plant.

If you are growing Red Ivy as a container or potted plant, repot with fresh soil early in the springtime. However, you may not find it necessary to repot every year. 

If the plant seems overcrowded in its pot or roots start to sprout from the drainage holes, you’ll know it’s time to repot. 

When grown as an annual or outdoor perennial, add leaf mold and compost to the moist soil to enrich it.

When grown as a houseplant, you can opt for commercial potting soil or an all-purpose potting mix.

Grooming and Maintenance

Remove dead and damaged leaves from your Purple waffle plant as needed. You can also trim lightly throughout the growing season to shape your plant or dig the offshoots, rooting themselves around the main plant, to keep the shape.At the end of summer, take cuttings from outdoor plants to start indoors and keep them as houseplants through the winter. When kept as houseplants, Cemetery Plants appreciate an occasional dusting to help keep the leaves bright and glossy and facilitate good photosynthesis. Indoors or outdoors, you may wish to spray your plants monthly with insecticidal soap or a neem oil solution to help prevent pest infestation. 

How To Propagate Purple Waffle Plant

It is easy to propagate Purple Waffle Plant through vegetative cuttings in water or soil. The plant spreads enthusiastically in the landscape and sets down roots as it rambles along. 

You only need to cut an actively growing stem with at least one node at the end using clean scissors or hand-pruning shears.

Then, plant the stem cutting in a container with moist potting soil.

You can also propagate Waffle Plant through division when you repot containers or potted plants. 

Red Ivy Main Pests Or Diseases

Whiteflies, mealybugs, and scale are the common problematic pests for this plant. 

Tackle whiteflies by soaking and rinsing your entire plant in your sink or shower. Pests leaving honeydew secreted saps and cottony matters may affect the underside of the leaves.

When you see them flying around your plants, you can also use the hose attachment on your vacuum cleaner to suck them up, but be careful not to damage your plants. 

If you see mealybugs on the plant’s undersides of the leaves, use a cotton ball soaked in isopropyl alcohol to wipe them away. 

Scale insects appear as small brown bumps on the stems and leaves of your plants. You can gently scrape them away with the edge of a knife blade or your thumbnail. 

If there are a lot of them, you may be better off pruning away heavily-infested stems and leaves. 

Follow up spot treatment for any of these pests with a thorough treatment of insecticidal soap spray or neem oil spray. 

Overwatering and excessive humidity can cause common problems with root rot and other fungal infections. 

If this happens, prune away affected leaves, stems, and roots using a very sharp, sterilized cutting implement. In addition, adjust your care habits to avoid excessive amounts of moisture. 

Repot your plant into an entirely clean potting mix and a new or sterilized pot or container. 

Take care not to overwater the plant in the future. Instead, provide gentle air circulation around your plants to help prevent fungal growth on leaves and stems.
