About Rosette Row
Rosette Row is a working record of one balcony succulent collection, kept in the order a shelf imposes rather than the order a search engine prefers. Every species file, care guide and propagation log on this site describes a plant that is physically present and a job that was actually done.
Why light is written in lux
"Bright indirect light" is not a measurement. It means a north-facing windowsill in one house and a 400 W grow tent in another, and a plant that gets the first will etiolate in a fortnight. This collection records light as a number so the instruction survives leaving the room it was written in. Where a figure is given as a range — 28,000–45,000 lux, say — the lower bound is the point at which the rosette starts to open and the upper bound is where the leaves begin to scorch in still air.
The same reasoning applies to water and to substrate. Watering intervals are given in days at a stated temperature, because a pot that dries in nine days in May takes twenty-two in December. Substrate is given as a volume ratio of named fractions, because "well-draining mix" tells you nothing you can act on.
How the figures are drawn
Every rosette, light bar, seasonal band and stage diagram on this site is a parametric SVG generated at build time from the parameters printed on the page it appears on. The petal count, the ring count and the form come from the species record; the gauge readings come from the watering interval, the light ceiling and the cold floor. Nothing is a photograph, a stock image or a bitmap, and no two species in the collection produce the same figure.
That has a practical consequence for the reader: if a figure looks wrong, the parameter underneath it is wrong, and you can check it against the tables on the same page. It also means the whole site loads without a single image request beyond the SVG itself.
What this site is not
This is a cultivation record, not horticultural advice, and not a plant-pathology service. The numbers describe what happened on one balcony in a temperate northern-hemisphere climate, in a specific substrate, under a specific light rig. You should expect your own results to differ, and you should treat any treatment mentioned here — fungicide, miticide, sterilising agent — as subject to the product label and to local regulation.
There is no sponsored content on this site. Species are not included because a supplier sent them, and no page carries an affiliate link. Where a product is named by type — 3 to 5 mm pumice, a 100 W LED bar — it is because that is what the plant in question is actually growing in.
Updates and corrections
The collection is written up as it changes rather than all at once: entries carry a publication date and are released in the order the work was done. Substrate ratios and light figures are revised when a plant is moved or repotted, and the revision is made in place rather than appended as a new entry.
If a number on this site does not match what you observe in the same conditions, that is worth writing in about. Corrections are welcome at [email protected] and are made on the page, with the date changed.
