Plants That Look Like Watermelon

Watermelon peperomia and watermelon begonia both mimic that striped rind pattern, yet they need completely different growing conditions to thrive. If you are hunting for plants that look like watermelon, you have a few solid options beyond those two famous ones. Some mimic the striped leaves, while others produce actual fruit that looks like a tiny melon.

This guide covers the best lookalikes, how to care for them, and how to tell them apart. You will learn which ones work indoors, which ones need full sun, and which ones are actually edible. Let’s get straight to the list.

Several species have evolved to resemble watermelon in some way. The most common are the peperomia and begonia, but there are also trailing vines and even a succulent that fits the bill. Here is a breakdown of the top contenders.

Watermelon Peperomia (Peperomia Argyreia)

This is the most popular houseplant that looks like a watermelon. Its leaves are oval, fleshy, and marked with silver stripes that radiate from the center. The pattern is uncanny.

Leaf pattern: Silver and green stripes, very similar to a watermelon rind.
Growth habit: Compact, bushy, stays under 12 inches tall.
Light needs: Bright, indirect light. Direct sun will scorch the leaves.
Water: Let the top inch of soil dry out completely before watering.
Humidity: Prefers moderate to high humidity, but tolerates average home air.

This plant is non-toxic to cats and dogs, which makes it a safe choice for pet owners. It is also slow-growing, so you do not need to repot it often. The stems are fragile, so handle it with care when moving it.

Watermelon Begonia (Pellionia Pulchra)

Do not let the name fool you. This is not a true begonia, but it is often sold under that common name. The leaves are dark green with light green or silver markings along the veins. The pattern is more like a mosaic than a striped rind, but it still reads as “watermelon” to most people.

Leaf pattern: Dark green with lighter veins, creating a quilted look.
Growth habit: Trailing or creeping, perfect for hanging baskets.
Light needs: Medium to bright indirect light. Low light makes the pattern fade.
Water: Keep the soil consistently moist, but never soggy.
Humidity: Needs high humidity. Use a pebble tray or a humidifier.

This plant is a ground cover in its native habitat. It grows fast and will spill over the edges of a pot. If you want a trailing plant that looks like watermelon, this is your best bet. It is more demanding than the peperomia, so be ready to mist it regularly.

Melothria Scabra (Mexican Sour Gherkin)

This is a vining plant that produces actual fruit that looks like a miniature watermelon. The fruit is about the size of a grape, with green and white stripes. It is edible and tastes like a cucumber with a hint of sourness.

Planting: Start seeds indoors 4-6 weeks before the last frost.
Support: Provide a trellis or fence. The vines can reach 6-8 feet.
Sun: Needs full sun, at least 6-8 hours per day.
Harvest: Pick the fruit when it is firm and about 1 inch long.

This is an annual plant, so it will die after one growing season. It is a fun conversation piece for a vegetable garden. The fruit looks exactly like a tiny watermelon, which is why it makes this list.

String Of Watermelons (Curio Rowleyanus Var. …)

This is a rare succulent that is a variation of the string of pearls. The leaves are small, round, and striped like a watermelon. It is not commonly found in big box stores, but you can order it online from specialty succulent nurseries.

Leaf pattern: Green with darker green or purple stripes.
Growth habit: Trailing, with stems that can grow several feet long.
Light needs: Bright, direct light for several hours a day.
Water: Let the soil dry out completely between waterings. Overwatering kills it fast.

This succulent is more delicate than the peperomia. It needs excellent drainage and a gritty soil mix. If you are new to succulents, practice with a regular string of pearls first before trying this one.

Watermelon Pilea (Pilea Cadierei)

Sometimes called the aluminum plant, this species has leaves with silver patches that can look like a watermelon pattern from a distance. The markings are more like blotches than stripes, but it is a close relative of the peperomia and has a similar care routine.

Leaf pattern: Green leaves with silver quilted patches between the veins.
Growth habit: Upright, bushy, can reach 12 inches tall.
Light needs: Bright, indirect light.
Water: Keep the soil lightly moist. Do not let it dry out completely.

This plant is very easy to propagate. You can take a stem cutting and root it in water in about two weeks. It is a good alternative if you cannot find a true watermelon peperomia.

How To Tell Them Apart

It is easy to confuse these plants at a glance. Here is a quick comparison chart to help you identify what you are looking at.

Peperomia: Upright, thick waxy leaves, distinct silver stripes radiating from the center.
Begonia (Pellionia): Trailing, thin leaves, pattern follows the veins, not the center.
Pilea: Upright, thin leaves, silver blotches, not stripes.
Melothria: Vine with true fruit, not just patterned leaves.
String of Watermelons: Trailing succulent, round striped beads.

If you are still unsure, look at the stems. The peperomia has thick, succulent-like stems. The Pellionia has thin, wiry stems that break easily. The pilea has slightly fuzzy stems when young.

Care Tips For Striped Leaf Plants

Most of these plants have similar basic needs, but there are a few critical differences. Getting these wrong will cause the leaves to lose their pattern or rot.

Light Requirements

Striped leaves need enough light to produce chlorophyll in the green parts and reflect light in the silver parts. Too little light and the stripes fade. Too much direct sun and the leaves burn.

Place peperomia and pilea near an east-facing window.
Place Pellionia in a north or east window, but never in direct afternoon sun.
Place the string of watermelons in a south or west window.
Rotate the pot every week so all sides get equal light.

If you notice the silver stripes turning yellow, the plant is getting too much light. If the whole leaf turns dark green, it needs more light.

Watering Schedule

Overwatering is the number one killer of these plants. The peperomia and the string of watermelons store water in their leaves and stems. They can survive drought, but they will rot if left in wet soil.

Water peperomia only when the top 1-2 inches of soil are dry.
Water Pellionia more frequently, but check the soil first.
Water the string of watermelons only when the soil is bone dry.
Always use a pot with a drainage hole.

If you are unsure, wait one more day. These plants recover from underwatering much faster than from root rot.

Soil And Potting

All of these plants need well-draining soil. A standard potting mix is too heavy for the peperomia and the succulent. You need to add perlite or coarse sand.

For the peperomia and pilea, use a mix of 2 parts potting soil, 1 part perlite, and 1 part orchid bark. For the string of watermelons, use a cactus mix with extra pumice. The Pellionia is less picky, but it still hates soggy roots.

Fertilizing

These plants are light feeders. Too much fertilizer causes salt buildup, which burns the roots and makes the leaf edges turn brown.

Feed once a month during spring and summer.
Use a balanced liquid fertilizer diluted to half strength.
Do not fertilize in winter.
Flush the soil with plain water every few months to remove salts.

If you just repotted your plant, do not fertilize for at least 6 weeks. The fresh soil has enough nutrients.

Common Problems And Fixes

Even with good care, you might run into issues. Here are the most common problems and how to solve them.

Leaves Curling Or Drooping

This usually means the plant is either overwatered or underwatered. Check the soil. If it is wet and the leaves are drooping, you have root rot. If it is dry and the leaves are curling, you need to water immediately.

For root rot, take the plant out of the pot, cut away any mushy roots, and repot in fresh dry soil. Do not water for a week.

Brown Leaf Edges

This is usually a humidity problem, especially for the Pellionia. It can also be caused by fluoride in tap water. Use distilled water or rainwater. Increase humidity with a pebble tray.

Faded Stripes

If the silver stripes are not as visible, the plant is not getting enough light. Move it to a brighter spot. Do not move it directly into full sun, or it will burn. Acclimate it over a week.

Propagation Methods

All of these plants are easy to propagate. This is a great way to get more plants for free or share them with friends.

Stem Cuttings In Water

This works for the peperomia, pilea, and Pellionia.

Cut a 3-4 inch stem with at least two leaves.
Remove the bottom leaf.
Place the cutting in a glass of water.
Change the water every 3 days.
Wait for roots to grow to 1 inch long.
Plant in moist soil.

Roots usually appear within 2-3 weeks. Keep the new plant out of direct sun until it is established.

Leaf Cuttings For Peperomia

You can also propagate peperomia from a single leaf.

Cut a healthy leaf with a bit of stem attached.
Insert the stem into moist potting mix.
Cover the pot with a plastic bag to create humidity.
Place in bright, indirect light.
Wait 4-6 weeks for a new plant to form at the base.

This method is slower, but it works well.

Where To Buy These Plants

Watermelon peperomia is common at garden centers and big box stores. You can find it in the houseplant section. The Pellionia is less common, but you can find it at specialty nurseries or online. The Melothria seeds are available at most seed catalogs. The string of watermelons is the hardest to find, so check Etsy or rare plant shops.

When buying online, check the shipping temperature. These plants are tropical and will not survive cold weather during transit. Order in spring or early summer.

Frequently Asked Questions

Are Watermelon Peperomia And Watermelon Begonia The Same Plant?

No. The watermelon peperomia (Peperomia argyreia) has upright, thick leaves with silver stripes. The watermelon begonia (Pellionia pulchra) is a trailing plant with thin leaves and a different vein pattern. They are not related botanically.

Can I Eat The Fruit From A Melothria Scabra?

Yes. The fruit is edible and tastes like a sour cucumber. You can eat it raw, pickle it, or add it to salads. Do not eat the leaves or stems, as they are not commonly consumed.

Why Are The Stripes On My Peperomia Fading?

This is almost always a light issue. The plant needs more bright, indirect light. Move it closer to a window, but avoid direct afternoon sun, which can burn the leaves.

Is The Watermelon Peperomia Toxic To Pets?

No, the Peperomia argyreia is non-toxic to cats and dogs. The Pellionia is also considered safe. However, the Melothria fruit is edible for humans, but you should keep it away from pets to avoid stomach upset.

How often should I repot my watermelon peperomia?

Only repot when the roots are coming out of the drainage holes. This usually happens every 2-3 years. When you repot, go up only one pot size. A pot that is too large will hold excess water and cause root rot.

Final Thoughts On Watermelon Lookalikes

You have several great options if you want plants that look like watermelon. The peperomia is the easiest for beginners. The Pellionia is perfect for hanging baskets. The Melothria is a fun edible novelty for outdoor gardens. The string of watermelons is a rare treat for succulent collectors.

Pick the one that fits your space and light conditions. Start with one plant, learn its quirks, and then expand your collection. These plants are not difficult, but they do require attention to watering and light. Get those two things right, and you will have a thriving striped beauty for years.

If you are still unsure which one to choose, go with the watermelon peperomia. It is the most forgiving, the most widely available, and it looks the most like a real watermelon rind. You will not regret it.
