Key Identifying Features
The Waffle Plant (Hemigraphis alternata, also sold as H. colorata 'Exotica'), or red ivy/red-flame ivy, is a low spreading houseplant named for its heavily puckered, quilted leaves that look like a waffle, metallic grey-green to purple above and vivid purple-maroon below.
- Leaves deeply textured/puckered (bullate), like a waffle iron print
- Upper surface silvery grey-green with a metallic purple sheen
- Undersides bright wine-purple to magenta
- Low, trailing/spreading habit with purplish stems
Leaves & Stems
Leaves are oval to heart-shaped with toothed/scalloped margins, arranged oppositely, and the surface is strongly crinkled and dimpled between the veins, giving the namesake waffle texture. The color is a shifting metallic grey-violet on top, intensifying to purple in bright light, with a striking purple underside that shows as leaves flip in a breeze.
Stems are soft, purplish, and trailing, rooting where nodes touch soil, so the plant forms a low spreading mat. It is in the Acanthaceae family, related to polka dot plant and nerve plant.
Flowers & Fruit
Flowers are small, white, bell- or funnel-shaped, borne in short terminal spikes, modest and not the reason for growing the plant. Bloom is occasional indoors. Fruit is a small capsule. The plant is identified almost entirely by its distinctive waffled, purple-backed foliage.
How to Tell It Apart from Look-Alikes
- Purple heart/wandering types (Tradescantia) are solid purple and have smooth, non-waffled, lance-shaped leaves and three-petaled flowers.
- Polka dot plant (Hypoestes) is upright with pink-spotted, only lightly textured leaves, not metallic purple-backed waffles.
- Rex begonia can be metallic but has large lopsided leaves and a rhizome, not a low trailing mat.
- The strongly puckered metallic grey-green leaf with a bright purple underside on trailing stems is unique to Hemigraphis.
Where You'll Find It
Native to tropical Southeast Asia (Java and surrounding regions), growing as a ground-creeping plant in warm humid shade. Grown worldwide as a houseplant, terrarium plant, and warm-climate groundcover or hanging-basket filler. It loves humidity and bright indirect light to keep the purple tones.
Quick ID Checklist
- Deeply puckered, waffle-textured leaves
- Metallic grey-green/purple upper surface
- Bright wine-purple undersides
- Low, trailing, mat-forming purplish stems
- Small white funnel-shaped flowers occasionally
Frequently asked questions
Why does the plant look metallic and purple?
Waffle plant naturally has a metallic grey-green to purple upper leaf surface and a bright purple underside. The color deepens in bright, indirect light and is key to identifying it.
What gives the leaves their bumpy waffle texture?
The leaf surface is strongly puckered (bullate) between the veins, creating a quilted, waffle-iron appearance that gives the plant its common name.
How do I tell it from purple heart (Tradescantia)?
Purple heart has smooth, solidly purple, lance-shaped leaves, while the waffle plant has crinkled, metallic grey-green leaves with contrasting purple undersides.
Does the waffle plant flower?
Occasionally it produces small white funnel-shaped flowers, but they are minor. The plant is grown and identified by its distinctive purple, waffle-textured foliage.
