flowers

The goal of flowers is to provide a lodgepole pine flowering phenology dataset in an accessible format. This package contains 15 years of lodgepole pine (Pinus contorta var. latifolia) phenology data for pollen shed and cone receptivity. The data were collected in seed orchards in British Columbia and represents multiple BC provenances.

Installation
