Crassula barbata - 20 seeds
Crassula barbata (Bearded Leaved Crassula) is a biennial or annual rosette-forming succulent species up to a span high when flowering, usually with one rosette with leaves spirally arranged and old ones remaining attached to stems. Leaves are glabrous but characteristically bearded along the truncate apex with long white spreading hairs. The spikes of small, white to pinkish flowers appear in spring. The rosette will open up as the centre extends to form the tall flower stem, and after flowering it will die. Fortunately the dying rosette usually produces a number of basal rosettes which can be detached and grown on to repeat the cycle.
Crassula barbata is a one of the most frustrating species to grow, but properly grown, in a compost that is not too rich, in a good light, and not overwatered, a single rosette will become a beautiful sight as the leaves curve inwards and the plant assumes the appearance of a hairy ball. They are often grown in small bonsai pots. Growth rate: It is a pretty fast grower. Soil: Plants grow well in a well-drained mineral soil. Pots: It needs a relatively shallow pot to accommodate its fibrous roots and provide a very good drainage. Exposure: It cannot take direct sun in summer, too much sunshine and the leaves will scorch, but generally needs sun part of the day to bloom. In deep shade it gets pretty weak and eventually rots and dies. As houseplants, give crassulas up to 6 hours a day of sun. Watering: It needs moderate water – not too wet nor too dry from autumn to spring with regular water in summer (careful watering required in winter), insufficient water and they will shrivel; too much water and the rosette will open up into a hairy cabbage. Fertilization: Light fertilizer seems to boost its growth whenever additional water is given. Feed it during the growing season with a fertilizer specifically formulated for cactus and succulents (high potash fertilizer with a dilute low nitrogen), including all micro nutrients and trace elements diluted to ½ the strength recommended on the label. It thrive in poor soils and needs a limited supplies of fertilizer to avoid the plant developing excess vegetation, which is easily attacked by fungal diseases. Special need: Provide very good ventilation. Nearly all problems occur as a result of overwatering and poor ventilation, especially when weather conditions are dull and cool or very humid. Pest and diseases: It does not suffer from pests, other than the occasional mealybugs. Protect against frost. Hardiness: Outdoors in frost free areas, indoors all other zones. Propagation: Seeds/ Offsets. Sow seeds in autumn. Place cuttings in clean river sand, mist every three to four days, roots should appear within 2-3 weeks. More...
