Nicotiana × sanderae 'Starmaker Lime' · also called Starmaker Lime Nicotiana, Lime-green Flowering Tobacco · flowering
A compact bedding flowering tobacco bearing masses of upward-facing, star-shaped flowers in a fresh lime-green that pairs with almost any colour scheme. From the well-branched Starmaker series, 'Starmaker Lime' is bred for tidy mounds, weather tolerance, and non-stop bloom in beds and containers. It performs in sun to part shade and draws pollinators through summer.
Preferred mix: Fertile, moisture-retentive but well-drained soil or quality potting mix
Watch for — Wilting when soil dries: Flowering tobacco droops fast in dry conditions. Keep soil evenly moist, mulch beds, and check containers daily during hot, sunny spells.
Why nicotiana × sanderae 'starmaker lime' needs this mix
Nicotiana × sanderae 'Starmaker Lime' hates drying out, so it wants a mix that stays evenly moist — but it still needs perlite so "moist" never tips into "waterlogged".
- Nicotiana × sanderae 'Starmaker Lime' comes from damp, shaded forest floors and has fine roots that scorch and brown the moment the rootball dries — the mix has to hold a steady reserve.
- Coir and compost give that reserve, while perlite keeps enough air that the constantly-moist mix does not turn anaerobic.
- Even moisture also keeps its thin leaves from crisping at the edges, which is this plant’s most visible stress signal.

What goes wrong with the wrong mix

- A free-draining, gritty mix dries too fast for nicotiana × sanderae 'starmaker lime' — you get crispy brown edges and frond or leaf drop within days of one missed watering.
- A pure, airless peat mix swings the other way: it holds water but suffocates the fine roots and rots the crown.
- Letting the mix dry to the point it shrinks from the pot is very hard to re-wet evenly and stresses the plant badly.
