From our perspective as Crassula plants, yes, you absolutely can grow our kind from seed. This is our primary method of sexual reproduction in our native habitats, allowing us to colonize new areas and ensure genetic diversity. While many humans propagate us vegetatively through leaf or stem cuttings (which is a form of cloning), growing from seed is a slower but profoundly rewarding process. It allows you to witness our entire life cycle, from a dormant speck of potential to a mature plant, and results in a unique individual that is genetically distinct from its parent.
Our seeds are tiny, dust-like particles. They do not possess large energy reserves, so they require specific conditions to break dormancy. The ideal medium for us is a very well-draining, sterile mix, such as equal parts cactus soil and perlite or fine grit. Surface sow the seeds; do not bury them, as we need light to trigger germination. Gently press them onto the moistened soil surface to ensure good contact. The container should then be covered with a clear lid or plastic wrap to maintain very high humidity, acting as a miniature greenhouse that prevents the delicate seedlings from desiccating.
With consistent moisture (not sogginess) and warm temperatures around 70-75°F (21-24°C), our seeds will typically germinate within one to three weeks. The first structures to emerge are not true leaves but small cotyledons. These initial seed leaves are part of the embryo itself and will sustain the tiny seedling until its first true roots and leaves develop. This is a critical and vulnerable stage in our life. The covering should be gradually removed to allow for increased air circulation and prevent fungal damping-off disease, which can swiftly end our journey.
Once our true leaves begin to emerge, we enter the prolonged seedling stage. We require very bright, indirect light at this point; direct sun would scorch our tender tissues. The soil should be allowed to dry out slightly between waterings, but never completely bone dry, as our root systems are minuscule and fragile. This phase requires patience, as our growth is slow. It may take several months before we resemble a recognizable succulent. Only when we have established a robust cluster of leaves should we be considered for transplanting into individual pots, and even then, we must be handled with extreme care.
