Gaultheria antipoda G. depressa
These are our Ericaceous dwarf shrubs. Mature seed may be collected in late summer or early autumn. The three species mentioned need light for germination, and are little effected by stratification. Germination may be slow with a burst about 3 weeks after sowing. Germination can proceed spasmodically for 3 or 4 months. However, in the wild germination and establishment of some seedlings would occur before winter, with shade or low temperatures suppressing germination until spring for some individuals. The strategy seems to be rapid germination with the possibility of some germination over a much longer period.
