Drosera bulbosa

Drosera bulbosa (or Drosera bulbosa ssp. bulbosa) usually is a pale-green species reaching up to 6 cm in diameter. The colour will change to golden-yellow towards the end of the growing season. This species produces up to 8 scapes 2 to 3 cm long each with a single flower.
D. bulbosa can be distiguished from D. rosulata by the golden-yellow colour and the raised ridge along the length across the middle of the leaf. The tubers are red.

Tubers of typical plants



Typical plant in the during the first half of the growing season. Please note the raised mid rib of the leaves.





Emerging plant of the Eastern Wheatbelt Form. The plant emerges with the leaves protecting the developing flower buds and it starts to flower while the leaves are unfolding.


Plant with swelling seed pods. The plant has developed its leaves now.

Narrow Leaf Form

A colourful form with - surprise, surprise - narrow leaves. In contrast to the colouration of typical plants (green early in the season, slowly changing to yellow) this form shows quite a reddish colour due to the intense colouration of its tentacles.


Tubers of narrow leaf form



Emerging plant of the narrow leaf form. All leaves are already visible but are not yet fully developed. In the background you can see a full grown plant past its flowering season.


Flowering plant. This species flowers early in the growing season. As you may have noticed, even at this stage some leaves are not fully developed.


Flower. The flowers open for a single day only (unlike e.g. D. macrophylla or D. monantha flowers).
