Rex Begonia

Why Rex Begonia Steals the Show

Forget flowers — the Rex Begonia is all about those jaw-dropping leaves. Swirls of metallic silver, deep burgundy, emerald green, and rosy pink create patterns so intricate they look hand-painted. No two leaves are exactly alike.

A Collector's Favorite

Often called the "painted-leaf begonia," Rex Begonias have earned a cult following among houseplant enthusiasts. They are a bit more particular than your average beginner plant, but the payoff is extraordinary foliage that draws every eye in the room.

Popular Varieties

• Escargot: Spiral-curled leaves resembling a snail shell
• Fireworks: Silver leaves with purple veins and edges
• Red Kiss: Deep red-black leaves with a metallic sheen
• Silver Dollar: Large silver leaves with green veining

Year-Round Color

While many houseplants rely on flowers for color, Rex Begonias deliver vibrant hues 365 days a year entirely through their foliage. Place one on a side table or shelf and watch it become the instant conversation starter.

Keep the soil consistently moist but never soggy — think of a wrung-out sponge. Water when the top half-inch feels dry, typically every 4-5 days in summer and weekly in winter. Always water at the base to keep leaves dry.

Tip: Bottom watering works beautifully for Rex Begonias and prevents crown rot.

Bright, indirect light brings out the best leaf colors. An east-facing window is ideal. Too much direct sun fades the patterns and scorches leaves. Too little light stretches stems and dulls the colors. Grow lights work wonderfully in darker rooms.

A light, airy mix is essential. Combine peat-based potting soil with perlite and a handful of orchid bark. The roots are shallow and delicate — heavy soil suffocates them quickly.

Feed every two weeks during spring and summer with a balanced liquid fertilizer at quarter strength. These are sensitive — too much fertilizer burns the delicate roots. Stop feeding entirely in winter when growth slows.

Leaf cuttings are the classic method. Cut a healthy leaf, make small slits across the major veins on the underside, and lay it flat on moist soil. Pin it down gently. New plantlets emerge from the cuts in 4-6 weeks. Rhizome division also works during repotting.

Repot every 1-2 years in spring using a shallow, wide pot. Rex Begonias have shallow root systems — a deep pot holds too much moisture below. Choose a container only slightly larger than the current one.

Crispy leaf edges: Humidity too low — aim for 50%+ and consider a pebble tray.
Powdery mildew: Poor air circulation plus wet leaves. Improve airflow and water at the base only.
Leggy, reaching stems: Not enough light — move closer to a window.
Leaf drop: Overwatering or sudden temperature changes are the usual culprits.
