When does Sidneya tenuifolia bloom in Texas?
Most often in February. Across 379 dated, research-grade observations of Sidneya tenuifolia in Texas, the flowering season runs roughly January to December.
Flowering 379 in flower of 387 examined
Peak flowering in Feb. Each bar is the share of Sidneya tenuifolia in Texas 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. 379 of 387 examined observations were in flower, every one of them research grade. The whisker on each bar is a 95% Wilson interval. 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 Texas found Sidneya tenuifolia in flower, not a forecast. It is computed only from observations made in Texas, 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.
