Pygmy Drosera

Drosera mannii

Drosera mannii in cultivation.

 

This is a guide to help identify pygmy Drosera common in cultivation.

The first picture of the plant is taken early in the growing season showing them at their "best". You can get the scale of the plants by looking at the sand grains. The soil surface has 16 mesh silica sand, about 1.5 mm diameter, in all the plant photos. The flower photos were taken as close as possible so the details of the flower morphology can be seen. Note the differences in the naughty bits as well as petal shape, color, and pattern. The photos of plants in an 83mm square pot ARE to scale. The images show an 8 cm square.

Species names were verified using Lowrie, A., R. Nunn, A. Robinson, G. Bourke, and A. Fleischmann (2017) Drosera of Oceana. IN: Drosera of the World, Volume 2. Redfern Natural History Productions, Poole, Dorset, England.

Species

Drosera dichrosepala (?)

Distributed as Drosera paleacea.

 

 
 

In cultivation.

Drosera echinoblastus

The flowers are large for such a small plant, about 2 cm across, and an orange metallic. After blooming the plants enter summer dormancy. It takes a lot of energy to make those flowers and many plants don't survive the effort.

 

 
 

In cultivation.

Drosera mannii

This species blooms early in the season so the plants don't produce flowers their first year from gemmae.

Drosera meristocaulis

This species is found on the Cerro de la Neblina tepuis along the border of Venezuela and Brazil.

 

 
 

In cultivation.

 
 
 

Drosera occidentalis

This plant is tiny. Each flower may produce one or two seeds.

 

 
 

In cultivation.

Drosera omissa

This is a rather large pygmy. It produces seed readily and grows quickly. (was Drosera ericksoniae)

 

 
 

In cultivation.

Drosera oreopodion

This plant is much like a white flowered Drosera echinoblastus. The flowers are smaller and there are more of them per plant. It's grow habit is identical with dormancy after flowering.

 

 
 

In cultivation.

Drosera parvula (?)

 

 

 
 

In cultivation.

8cm x 8cm image of plants.

 
 
 

Drosera patens

A relatively boring plant that has been the mother of many spectacular hybrids. It is quite fecund.

 

 
 

In cultivation.

Drosera pedicellaris

 

 

 
 

In cultivation.

8cm x 8cm image of plants.

 
 
 

Drosera pulchella

This species has very nice flowers and grows well in terrariums. It has many flower color variants from red to white to orange. It does best when summers are relatively cool. It produces seeds.

 

 
 

In cultivation.

Drosera roseana

This is a great pygmy. The plants are very cute and do well in terrariums. It will not bloom or produce gemmae in terrariums. 

 

 
 

In cultivation.

Drosera scorpioides

This is the easiest pygmy to grow. It is large and grows fast. It can live for years in a terrarium. I have had plants get 8 cm tall after a few years. This species blooms very early in the spring so only plants one year old or more will bloom.
