Lithops, often called “living stones,” are succulents that mimic pebbles in their native southern Africa. Their ability to blend into a rocky landscape is a primary fascination for growers. The emergence of a flower from the fissure between the two fleshy leaves is a significant event. This bloom indicates a healthy, well-cared-for, and mature plant, confirming the grower’s practices are aligned with the plant’s unique needs.
A Lithops plant reaching flowering maturity requires patience, as a plant must be three to five years old to produce its first bloom. Younger plants focus their energy on establishing a strong root system and developing their leaf bodies. Forcing a bloom before the plant is ready is often unsuccessful and can stress it. Once mature, they can rebloom annually under the right conditions.
Flowering is closely tied to the annual life cycle. Blooming occurs in late summer or autumn, following the plant’s main growing period. After growth and a summer dormancy, the plant channels its stored energy into producing a flower, which precedes the development of the next set of leaves.
Providing sufficient sunlight is a primary requirement for a Lithops to bloom. These plants are adapted to intense sunlight and need similar conditions in cultivation to photosynthesize and store energy for flowering. Place them where they can receive at least four to five hours of direct morning sunlight. An east-facing window is often suitable, as it provides bright light without the intensity of the afternoon sun, which can scorch the leaves.
Watering practices are deeply connected to the plant’s seasonal rhythm and are a primary trigger for flowering. During the spring and early summer, when new leaves are growing, the plant should be watered thoroughly, allowing the soil to dry out completely between waterings. As late summer and early autumn approach, watering should be reduced and then stopped. This period of dryness signals the plant to shift from vegetative growth to flower production.
A distinct winter dormancy period is another component for successful blooming. After flowering in the autumn, the plant enters a state of rest. During this winter period, from approximately November to April, watering should be withheld almost entirely. The plant will use this time to absorb the old outer leaves, drawing moisture from them to develop the new bodies growing inside.
When a mature Lithops flowers, a single bud emerges from the fissure separating the two leaves. The daisy-like flowers are often large for the plant’s size and are most commonly bright white or sunny yellow. Many species also have blooms with a sweet, often spicy, fragrance that is most noticeable in the afternoon.
The flower will open in the afternoon and close in the evening, a cycle that repeats for several days. The entire blooming period usually lasts for one to two weeks. Once the flower has finished its cycle, it will wither and dry up. Leave the spent bloom attached until it is completely dry and brittle, at which point it can be gently removed without damaging the plant.
If a Lithops fails to bloom, the first consideration should be its age. As previously mentioned, plants under three years old are generally not mature enough to flower.
For a mature plant that isn’t blooming, the most common reason is insufficient light. A plant that appears elongated or has lost its vibrant color patterns is likely not receiving enough light. Moving it to a brighter location may resolve the issue for the next blooming season.
Improper watering, particularly during the wrong season, can inhibit flowering. Watering a Lithops during its autumn flowering window or its winter dormancy period can confuse its natural cycle, causing it to focus on leaf growth instead of producing a bloom. A plant that does not experience a cool and dry winter rest period may not gather the necessary energy to flower later in the year.
