Puzzle bush (Ehretia alba) is a semideciduous, much-branched shrub or small tree of dry southern African shrubland and scrubland. Its native range includes Botswana, Namibia and South Africa. [2]
Description[edit | edit source]
The plant is described as reaching about 4 m and developing many branches. It is associated with dry shrubland or scrubland rather than a permanently wet forest setting. [2] The name was published in 2001; the type collection came from Breitenberg in Namibia's Gobabis District. [3]
Cultivation[edit | edit source]
Soil and water[edit | edit source]
The dry-shrubland habitat makes sharply drained soil a sensible starting point, with irrigation kept cautious rather than allowing the root zone to remain persistently wet. This is a habitat-based inference, not a tested Ehretia alba watering schedule. [2]
Sun and humidity[edit | edit source]
The same dryland origin supports beginning with bright light and good airflow rather than a stagnant, continuously humid position. Treat that placement as a habitat-based inference: the species' measured shade tolerance and humidity limits are not supplied by the available account. [2]
Seasonal changes[edit | edit source]
Because the plant is semideciduous and native to dry shrubland, seasonal changes in leaf cover should be expected. In cultivation, keep irrigation responsive to active growth and substrate moisture instead of maintaining a fixed wet-season schedule through the dry part of the year. This seasonal approach is an inference from habitat and habit, not a species-tested calendar. [2]
Propagation[edit | edit source]
Fresh seed is described as germinating rapidly. Use fresh seed when available; a numeric germination schedule, pretreatment, storage protocol and transplant procedure would be speculative from the present evidence. [4]
Flowering, fruiting, and harvest[edit | edit source]
The flowers are described as fragrant and white to cream. Mature fruit is red, nearly globose and fleshy, measuring about 4–6 mm across. [4] [5] A flowering calendar, pollination requirement, bearing age and more precise harvest index are not included here; the red mature color is the practical description available for recognizing fruit maturity. [4]
Fruit and uses[edit | edit source]
The small red fruit is locally eaten raw. Its flavor assessment is subjective: it has been described as tasteless to many adults while appealing to some children, so that characterization should not be generalized to every plant or growing condition. [4]
