Cultivation Details
Hesperocyparis sargentii is found wild at elevations up to 915 metres in the coastal ranges of California, where the climate is of the Mediterranean type with hot, dry summers and winter rain[1]. Grows well in a hot, dry situation[2]. Prefers a pH of 6 or lower[2]. Sargent Cypress is a fire-adapted, fire-dependent species. It has slightly fire-resistant bark and serotinous cones, although its low branching habit makes it susceptible to crown fires. Reproduction is generally restricted to burned sites[3]. Trees commence producing female cones when around 5 - 6 years of age or olde, and male cones from 6 - 7 years of age. Female cones require 2 years to mature and contain about 100 seeds each. When cones are closed they persist on the tree for several years until opened by the heat of a fire or from desiccation due to age, and then release the seeds over several months[3].. Detached cones will open, but they rarely result in seedling establishment in the wild, usually due to lack of a suitable seedbed[3].
Propagation
Seed - Seeds require bare mineral soil for germination and establishment. Seedling mortality is high on shaded sites with abundant litter because of damping-off fungi as seedlings are sensitive to excessive moisture. Seedlings are shade intolerant and survive best in full sunlight[3].
