Lithops Optica Rubra seeds very tiny seeds hardly visible to eyes, if you are uncomfortable with tiny seeds then these seeds maybe not for you
Lithops Optica Rubra seeds Description: (a.k.a. Stone plant) is a tiny perennial, caespitose, succulent plant resembling a grouping of tiny pebbles split down the middle like cleft hooves. It grows to a maximum eight of 4 cm above ground and spreads to form small clumps with up to 12 or more heads (usually 2-6). It is one of the more variable species, with uniformly coloured or variously ornamented plants, and yet with opaque or obscurely windowed forms; there is also a great variation in the colours. Plants from different localities show strikingly different colours or patterns, but all natural populations show some degree of variation among individuals, and in some all possible intermediates colours and pattens occur.
Stem: Almost stemless.
Lithops (commonly called „flowering stones“ or „living stones“) are true mimicry plants: their shape, size and color causes them to resemble small stones in their natural surroundings. The plants blend in among the stones as a means of protection. Grazing animals which would otherwise eat them during periods of drought to obtain moisture usually overlook them. Even experts in the field sometimes have difficulty locating plants for study because of this unusual deceptive camouflage.
In the wild, Lithops inhabit vast dry regions of southern Africa. Several areas in which these plants grow receive less than 2 inches of rainfall per month throughout the entire year. In an extreme situation of low rainfall, at least one species of Lithops depends on mist or fog to provide its main source of moisture *. Lithops could not survive in many areas that they are found were it not for their capacity to store water. In fact, almost the entire plant is devoted to this function. The “body” of the plant is divided into two succulent leaves fused together in the shape of an inverted cone. The fissure or slit at the top of the plant is the division of the two leaves. There is no stem as such, but rather the taproot joins abruptly at the base of the leaves. The structure of the plant reveals to the imagination the harsh environment in which Lithops live: the scarcity of water demands that young plants limited to only two leaves and a root system, as more extravagant growth would only serve to waste water. The leaves are thick to store enough water for the plants to survive for months without rain. The plants are small and keep a low profile to minimize the effect of the intense heat and light of their climate.
The above information can be taken into account when growing Lithops in the home or greenhouse. Because they thrive in low humidity and need infrequent watering and care, they make ideal houseplants, providing the conditions of adequate light and proper watering are met. Care must be taken to select a well lit location for the plants. Because they have adapted to intense sunlight in the wild during their evolution, they need a good amount of direct sunlight when grown as houseplants.
Lithops do well if they receive about 4 or 5 hours of direct (or only slightly filtered) sunlight during the early part of the day, and partial shade during the afternoon. Usually a southern window is the best location, unless it exposes the plants to full sunlight most of the day, which should be prevented. An unobstructed eastern exposure is a good alternative. A window facing west may be suitable, although not ideal, and of course a north facing window offers no direct sunlight at all.
If the plant do not receive a certain amount of direct sunlight for a few hours a day (when the weather permits, of course), they begin to grow slender and elongated, leaning to one side to receive more light. They also lose coloration and the sides of the plants turn greenish. They will eventually die if better lighting is not given them when these signs become evident. In some situations however, it is advisable to shade the plants a little from intense sunlight in the spring to prevent sunburn, especially in areas that experience poor light during most of the winter. This is because the plants lose resistance to bright light during a prolonged period of overcast weather, and the sudden brightness of a clear day will cause them to become burned, causing a whitish scar tissue to form on the surface of the plant. A badly burned plant may be so severely injured that it may die. This is why you should expose the plants to bright light gradually over a period of several days if they have been in dim light for some time. This is especially true of newly purchased plants.
