rubber plant · Asked on Facebook · 5 November 2026

What plant is this with thick dark leaves and a red central spike?

This is a Rubber Plant (Ficus elastica), likely a dark or ‘Burgundy’ type. The red “pencil-like flower” in the middle isn’t a flower at all, but the sheath of a new leaf that will soon unfurl.

The question

“Does anyone know what plant this is? It has unique, pencil-like flowers.”

What's likely going on

The plant in the photo is a Rubber Plant (Ficus elastica), commonly grown as a houseplant or small landscape tree. The variety looks like one of the dark-leaved types (often sold as ‘Burgundy’ or similar).

The red, pencil-like spike in the center is not a flower. It’s a leaf sheath – a protective wrapper around a new leaf. As the leaf grows, this red sheath will dry and fall away, and the new glossy leaf will unfurl from inside it.

Rubber plants do flower, but very rarely in home or garden conditions, and the flowers are not showy. Most people grow them just for their bold, shiny foliage.

What to do

  1. Let the “spike” be – it’s a normal part of growth. In a few days or weeks, watch for a new leaf to emerge from it.
  2. Give it bright, indirect light outdoors in light shade or indoors near a bright window. Strong afternoon sun can scorch leaves, deep shade slows growth.
  3. Water when the top of the soil feels dry. Don’t keep it constantly soggy; rubber plants dislike sitting in water.
  4. Check the pot and drainage if it’s in a container. Use a well-draining mix and a pot with holes.
  5. Wipe the leaves occasionally with a damp cloth to remove dust and let them breathe and shine.

How to prevent it

Nothing to prevent here – that red spike is just healthy new growth. To keep new leaves coming:

  • Avoid overwatering or letting the soil stay waterlogged.
  • Feed lightly with a balanced fertilizer during the growing season (spring–monsoon).
  • Keep it out of cold drafts or sudden temperature drops.

When to worry

  • If new spikes turn brown and mushy before opening, the plant may be overwatered or the soil may be poorly drained.
  • If leaves are yellowing and dropping in large numbers, check for root rot (sour smell, black roots) and improve drainage.
  • If you see sticky residue or tiny insects on leaves, look for pests like scale or mealybugs and treat promptly.

Also note: the sap of rubber plants is irritating and mildly toxic to pets and people, so avoid letting children or animals chew the leaves, and wash skin if the white sap gets on it.
