When does Asian mazus bloom in Mississippi?

Most often in February. Across 120 dated, research-grade observations of Mazus pumilus in Mississippi, the flowering season runs roughly February to November.

Peak February In flower 120 Examined 120 State Mississippi

Flowering 120 in flower of 120 examined

Peak flowering in Feb. Each bar is the share of Mazus pumilus in Mississippi observations in which someone actually recorded the reproductive state and found the plant in flower, not the raw number of flowering records. That distinction matters: people observe plants far more in spring than in winter, so a bare count of flowering records partly measures when people go outside. Dividing by the number examined removes that. 120 of 120 examined observations were in flower, every one of them research grade. The whisker on each bar is a 95% Wilson interval. 3 months have fewer than 5 examined observations, so no proportion is drawn for them. This is still a global aggregate and not a forecast for your garden: the same species flowers on different dates in different hemispheres. Where a species has fewer than 30 flowering records we do not draw this chart at all. Computed from 10.15468/dl.wt38fd.

What this is, and what it is not

This is a record of when people in Mississippi found Mazus pumilus in flower, not a forecast. It is computed only from observations made in Mississippi, so it is not the species’ global average dragged onto a map: the same plant flowers on different dates in different places, and that is the entire point of the page.

It will not tell you what your particular plant will do this year. Bloom time moves with the season, with altitude, and with the weather, and a warm February pulls everything forward. We publish the distribution and the sample size, and we refuse to draw a month that too few people examined.
