Description

Drosera arcturi is a perennial, temperate carnivorous species of sub-alpine or alpine herb native to Australia and New Zealand. This plant is a summer grower, and after flowering its leaves gradually reduce in size to form an elongated, horn-shaped hibernaculum.

Origin:
Australia

Description:

  • Climate: temperate
  • Life-cycle: perennial (Winter dormancy)
  • Form: erect
  • Leaf: green
  • Trap: green with slightly red like traps if exposed in full sun

Care instructions

How we grow Temperate Drosera?
In-vitro plants are acclimated in a Grow Chamber with controlled temperatures and humidity. This indoor setup ensure an easy adaptation to extra-vitro condition, guaranteeing the best conditions for plants in this delicate stage. All plants available at the Diflora shop have been acclimatized for at least 3 months. After this first step the plant is brought outside, under direct sunlight with the classic tray system as watering method and so, keeping always some amount of water in the tray. As with the majority of carnivorous plants, we use distilled water produced by our reverse osmosis system.

Lighting:
Full sun all year round! It is highly suggested to shade slightly in the warmer summer months to avoid excessive temperatures that may stunt the plant’s growth.

Watering:
Temperate Drosera likes stagnant water all year round (3-4 cm of distilled water always in the saucer). This serves to faithfully imitate the natural environment in which they live. It is important to use only distilled water or alternatively all waters that have an extremely low mineral salt content. For example rainwater or all condensation water (air conditioner, dehumidifier). The conductivity of the water must have a value of less than 50 micro-siemens.

Substrate:
While 50% peat and 50% perlite is fine as a general substrate, we recommend the mineral substrate for Drosera we have developed and tested for the optimal growth of plants that thrive on ultramafic soils.

Seasonally and temperature:
This Drosera is a carnivorous plant from Temperate climate, it’s grown outside all year long, under direct sunlight both in winter and in summer. The plant starts to sprout out from late March, early April and continue to grow until late October when the cold temperature become more and more strong. When fall comes Temperate Drosera produce a rosette of smaller dimension than the previous vegetative leaves with the aim of protect itself from freeze, exposing as less surface as it can to the below zero temperatures of winter. This resting period is called “dormancy”: the central part of the rosette stay alive while all the rest turns brown and seems to be dead. BUT IT’S NOT DEAD! It’s the normal seasonal adaptation of a subtropical Drosera that goes in dormancy until the first warm days of spring.

Diflora has begun the propagation of this Drosera using seeds germinated in vitro in our laboratory. This specimen was chosen for its uniqueness in terms of shape and color, resulting in a distinctive product in the market.

Trapping technique

Drosera catch mainly small flying insects using sticky modified trichomes placed all over their leaves. These trichomes secrete droplets of water and polysaccharides attracting insects that are searching for sugary substances, like nectar. As the unawares visitors fatally fly on those sweet and lethal leaves, they stay glued and unable to fly away. It is caused mainly by droplet viscosity. Slowly, the viscous liquid from the nearby trichomes envelops the insect, sealing a macabre fate for the unfortunate victim: the tracheas, respiratory holes placed on the surface of the exoskeleton of insects, are obstructed causing their death by suffocation.
