Bloom times

When a plant is actually in flower, state by state, computed from dated observations that people really made. The same species flowers on different dates in different places, and a national average is the wrong answer to a local question. Every curve here is built only from observations made in that state.

Why there is no page for your plant

A page appears here only when enough people in that state actually recorded whether the plant was in flower: at least 50 flowering observations, and at least four months with enough examined records for a proportion to mean anything. Below that the chart would be mostly blank, and a page whose only artefact is a chart with two bars on it is not a page. That threshold excludes far more species than it admits, and it is the reason the ones here can be trusted.
