Lithops gracilidelineata ssp. gracilidelineata v. waldroniae 'Fritzís White Lady' C189A

of Cacti and Succulents.


 Clear pastel body and knobbed top with fine brown lines  
 

Description*: This form appeared in 1980 among seedlings grown by Ernst E. Fritz from plants collected by D.T. & N.A. Cole in colony C189. No specimens have been found in habitat, but presumably they have occured there naturally at some time. This form is very similar to acf 'Ernst's Witkop' which may not really be distinct from it.
Flowers:  White (instead of yellow), but the plants otherwise indistinguishable from var. waldroniae and therefore identifiable only when in flower.

Remarks:
Lithops are partly subterranean, with only the clear 'window' in each leaf tip exposed above soil. A type of optical system exists whereby a layer of apical tissue rich in calcium oxalate crystals acts as a filter to intense sunlight before it reaches the thin chlorophyllous layer below. They are also called mimicry plants as they show a striking similarity to their background rocks and are difficult to detect when not in flower. These are the commonly known as pebble plants or living stones; each species is associated with one particular type of rock formation and occurs nowhere else. Its soil-embedded, subterranean growth form also reduces the need for chemical defences against herbivores.

Cultivation: Need an open mineral, fast draining mix and the maximum amount of light you are able to give them. The basic cultivation routine is: Stop watering after flowering. Start watering after the old leaves completely dry. (Usually late March or Early April) Water freely during the growing season, soak the compost fully but allow it to dry out between waterings, no water when cold. Some growers fertilize frequently, some hardly ever. Keep them dry during the winter. Nearly all problems occur as a result of overwatering and poor ventilation especially when weather conditions are dull and cool or very humid. This plant is best for a well lit area (Bright shade to full sun).

Family: Mesebrianthemaceae (Aizoaceae)

Scientific name:  Lithops gracilidelineata Dint. (1928) subsp. gracilidelineata var. waldroniae cv.  Fritz's White Lady (1985)

Origin: 60 km SE of Swakopmund, Namibia (TL)



Flowers are small and white.
 

 

 

Note: After flowering in the autumn and extending through winter season the plant doesnít need watering, but they will still be growing, the new bodies will be increasing in size extracting water from the outer succulent leaves, allowing them to shrivel away.  In fact the plant in this time extracts water and nutrient stored in the outer succulent leaves, allowing them to dehydrate relocating the water  to the rest of the plant and to the new leaves that form during this period until the old leaves are reduced to nothing more than "thin papery shells".
