growing rubies

verruculosa 1
Lithops verruculosa inae
C129 is an inconspicuous littel grey seedling. Things change whith the first pair of true leaves. Even through the ‘eye’ of the cotyledons you can spot the little red gems mounted on the Lithops.

After sowing, L. verruculosa germinated well, cotyledons and young plants always fragile in comparison to other Lithops seedlings.
verru dead head 2
The first summer was hard. A sudden death episode which affected a few species, as well as most of the nice little rubies. They don’t like to much water, nor watering in hot spells at all. I hope I recall next summer: more shadow for these!
rubies 4
Two of the happy survivors just at their birthday. One year old they prepare for a benign drought – the community compot gets more waterings and mistings than individual adult Lithops – and hopefully a new pair of leaves in springtime next year. The rubies have faded somewhat.

Anything but nice

Rarely you will find an entry dealing with our dead ones. The end of our efforts, the loss of a plants life, the sad outcome of a wrong culture. Though every gardener has made the experience, it seldom makes a subject for photographs. The failure in sucess is taboo. You don’t want to show nor share.

Taboo 1 optica rubraAlready bought as a replacement of another Lithops optica ‘Rubra’, this one didn’t survive the first summer. Odd colours bid farewell. And again there is no partner for the eventual flower of the remaining ‘Rubra’.

Taboo 2 verruculosaA young hatchling of Lithops verruculosa had successfully managed to grow it’s first pair of true leaves and then suddenly dies. The brothers of the same batch grow without problems.

Taboo 3 bromf mennelliiThis shrunken head of Lithops bromfieldii mennellii was a fairly recent acquisition. The biggest of three didn’t make it over the first watering. The other two are happy and growing.

Yesterday the day begun cloudy. Unshaded, the planter with Lithops seedlings stood in full sun for some hours as the day got sunnier. Some resented it and did not fully rehidrate during the night. They still are turgent to some extend though, so it  could be that those who went whitish are those preparing a new pair of leaves. There is always a bit of wishful thinking when it comes to taboos!

tabooDeath is spreading. Not only this four pretty verruculosa, but the  Frithia seedling, three more L. hallii, one L. dinteri, three L. fulviceps, … are collapsing. What begun as sun-stress has turned out being some much more virulent rot.

This is sad. No wonder I’d prefer not to write about it.

taboo 8 o 9
Did I mention? Water quality is paramount when watering the first time after summer – in fact, not only the first time, but every watering. Never use ‘old’, ‘rest’-water. The bacteria and other microorganism will feed on the Lithops. Even more if the weather is still warm. I know that. But why do I – mindlessly – just pour some old cup with water in it over my Lithops? Didn’t need to verify an old  theory ,,, This is part of what is left of Lithops lesliei albinica.

taboo 10
Still hope for this one, Lithops salicola, which has severe damage on one leaf. The rest is still turgid and looking right, so hopefully this one may survive.

The first leaves in the life of different Lithops species – a comparison

Lithops generally are easy to germinate. Most seeds, if not to fresh, will sprout in a few days, and there will be germinations many weeks later, too.

The embryo quickly forms a body, consisting of the two cotyledons or seed leaves and a tiny tap root.

At this stage, all you see is very green and extremely frail. Two green tips and a fissure in the middle – one millimeter all in all.

green cotyledon

The fine gravel looks like big boulders but soon the young plant will be able to push its way up to more light and sun. The tiny plant  changes quickly into the caracteristic shape of its species – a flat cotyledon like e.g. in L. lesliei or L. aucampiae, or barrel-shaped as for instance in L. bromfieldii. One other characteristic is the length of the tiny fissure, where the two fused cotyledons leave a gap for the next pair of leaves to emerge – the first true pair of leaves of the young Lithops plant.

 Lithops terricolor ‘peersii’ C131 has an apple-shaped cotyledon with short fissure. The hatchling changes  into a loaf-of-bread-like  shape with a short fissure.

verruculosa 39dverruculosa 51dverruculosa 170d

left: 39 days old; right: 51 days old, bottom: 170 days old

Lithops verruculosa var. verruculosa C129 has little, reddish-grey, barrel-shaped cotyledons with long fissure and a distinct pair of first leaves . The fissure extends over the whole face, bordered with ruby-red verruculae.

pseudotruncatella 36 dayspseudotruncatella 47dpseudotruncaella 176d

left: 36days old; right: 47days old; bottom:176 days old

Lithops pseudotruncatella ‘alpina’ C068 quickly forms ruby red, tiny barrel-shaped bodies. The colour fades to a dull greenish brown just until the first true leaves appear. The little plant is 2 – 4 mm wide. Very short fissure, hardly visible.

otzeniana 39dotzeniana 86dotzeniana 170d

left: 39days old; right: 86 days old; bottom: 170days old

Lithops otzeniana C280 does not germinate as readily. The young cotyledon-bodies are green with a red hue and apple-shaped. The fissure runs through 3/4 of the surface. While the first pair of leaves appear, the cotyedons persist and split deeply. The fissure of the newly formed body runs from side to side.

lesliei maraisiilesliei maraisii 86dlesliei maraisii 103d

left: 14days old; right: 86 days old; bottom: 103 days old

 The cotyledons of Lithops lesliei ‘Maraisii’ C 153 form a flat elliptic body, shiny, grey with a lilac hue, and a small central fissure. The first true pair of leaves resemble the adult Lithops and have a short, reddish fissure.

julii brunnea 39djulii brunnea 98djulii brunnea 138d

left: 39days old; right: 98 days old; bottom: 138 days old

Lithops julii brunnea C179 has green or dull coloured, barrel-shaped bodies,  with a long fissure that nearly runs from side to side. The emerging Lithops looks like the adult and has a complete fissure.

hookeri subfenestrata brunneoviolaceaHookeri subfenestrata brunneociolacea

left: 126 days old; right: 175 days old

Lithops hookeri var. subfenestrata ‘brunneoviolacea’ C019 makes fairly big, flat-topped, barrel-shaped cotyledons, reddish and dark, with short fissures. Just before hatching the cotyledons fade to a dull beige. The emerging colourful body is flat,  with a short fissure that sometimes runs over half or more of the surface.

hallii hallii 86 dayshallii hallii 138 days

left: 86 days old; right: 138 days old

Medium dark grey cotyledons are characteristic of Lithops hallii C119, shiny and flat, with a strong and long fissure over rhe whole face of the body. The first true leaves display a new colour, and a complete fissure.

julii fulleriJulii fulleri 170 days

left: 39 days old; right: 170 days old

A very distinct first pair of leaves emerge from small and inconspicuous cotyledons.  The cotyledons of Lithops julii var. fulleri C162A are round and dull coloured, the fissure is long. The new body formed by the two true leaves rises high above the slowly drying cotyledon, with a complete fissure and the fully visible grey conus of the typical Lithops. These plants have recieved the same amount of light and sun as all those previously shown!

aumpiae cotyaucampiae hatchling

both plants are 175 days old!

Lithops aucampiae C333 do their own thing. While some hatch and grow, others still await looking at the outside world. Flat, shiny cotyledons, barrel-shaped with a distinct concave face with a rim, grey or reddish, always dark, short fissure. The new pair of leaves form a nearly round, textured body, with a short fissure.

L. lesliei lesliei 'luteoviridis'Lesliei luteoviridis 173d

left: 86days old; right: 173 days old

Lithops lesliei lesliei ‘luteoviridis’  has flat, elliptic, rimmed cotyledons. The fissure is half the length of the smaller diameter. The first leaves look like a small Lithops luteoviridis; with a short fissure, as in all lesliei- seedlings I’ve seen.
