Every time a gardener marks a plant as blooming, Hortus records the day and how warm the season has been at that spot. Season after season, that becomes a picture of when native plants actually first bloom, garden by garden, that cannot be scraped from anywhere else.
This is an early, thin dataset. Every number below rests on a small sample, so treat it as a first glimpse, not a finding. That is exactly why it needs more seasons and more gardens.
| Species | Region | Logs | Typical first bloom |
|---|---|---|---|
| Rubus idaeus | Nova Scotia | 2 | too few logs to say |
| Monarda didyma | Ontario | 2 | too few logs to say |
| Achillea millefolium | Nova Scotia | 1 | too few logs to say |
| Asclepias incarnata | Nova Scotia | 1 | too few logs to say |
| Calendula officinalis | Nova Scotia | 1 | too few logs to say |
| Centaurea cyanus | Nova Scotia | 1 | too few logs to say |
Each record pairs a first-bloom date with the accumulated season warmth at that location, so shifts can be read against a real climate signal, not just the calendar.
No names, no addresses, no coordinates. Location is only ever the province or state, and the export carries no account identifiers at all.
This is a compounding dataset. The more gardeners log blooms, the more regions and species cross the threshold where the numbers start to mean something.
