❓❗ Why are my Cape sundew (Drosera capensis) flowers different colours?

Cape sundew (Drosera capensis) flower colour variation light pink vs deep pink

Short answer: Cape sundews (Drosera capensis) can produce slightly different flower colours — from soft light pink to deeper, richer pink tones — depending on the form and how the plant was grown.

At first glance, it can look like two completely different plants. But this is completely normal within Drosera capensis, which is known for its natural variation in colour, size, and growth.

This is especially common in one of the most popular beginner carnivorous plants, the Cape sundew, which is widely grown for its easy care and fast growth.

Why do the flowers look different?

There are a few key reasons why Cape sundew flower colour can vary:

  • Different forms: Wide-leaf plants often produce slightly darker, more vibrant flowers, while narrow-leaf forms tend to be lighter pink.
  • Light levels: Plants grown in strong light usually develop deeper, richer colours.
  • Growing conditions: Temperature and overall plant health can influence pigmentation.

Seed-grown vs cloned plants

Another important factor is whether the plant is seed-grown or cloned.

  • Seed-grown plants show natural variation — meaning flower colour, size and even leaf shape can differ slightly from plant to plant.
  • Cloned plants (divisions or tissue culture) are usually more uniform, with consistent appearance and flower colour.

This is why two Cape sundews growing side by side can look slightly different — and it’s often part of what makes them so interesting to grow.

Wide leaf vs narrow leaf – what does this mean?

You may hear growers refer to “wide-leaf” and “narrow-leaf” Cape sundews. These are not officially named varieties, but rather informal ways to describe how different plants grow.

  • Wide leaf: Plants with broader, more robust leaves and often a shorter, chunkier overall appearance.
  • Narrow leaf: Plants with thinner, strap-like leaves and a more delicate look.

These differences can sometimes be linked to flower colour, but there is a lot of natural variation — especially in seed-grown plants.

👉 Because of this, leaf shape and flower colour should be seen as general observations rather than strict identification rules.

Why this matters for growers

Small differences like this are completely normal and are often a sign of healthy, well-grown plants.

At Cultivo Carnivores, many of our sundews are seed-grown or carefully selected, meaning you’re getting strong, unique plants — each with their own subtle character, not just mass-produced clones.
