About Impatiens walleriana 'Xtreme Salmon'
Impatiens walleriana 'Xtreme Salmon' · also called Xtreme Salmon Impatiens, Busy Lizzie Salmon · flowering
A shade-loving busy lizzie with abundant flat salmon-pink flowers on a compact, mounded plant. Classic bedding and basket impatiens, it flowers non-stop in shade to part shade through summer. It needs consistently moist, humus-rich soil and shelter from hot afternoon sun, and remains self-cleaning, dropping spent blooms without deadheading right up to first frost.
Preferred mix: Rich, moisture-retentive but well-drained soil
Watch for — Wilting in heat or drought: Plants flag dramatically in hot sun or dry soil. Move to shade, keep soil evenly moist and mulch; they usually recover quickly once watered.
Why impatiens walleriana 'xtreme salmon' needs this mix
Impatiens walleriana 'Xtreme Salmon' hates drying out, so it wants a mix that stays evenly moist — but it still needs perlite so "moist" never tips into "waterlogged".
- Impatiens walleriana 'Xtreme Salmon' 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
The wrong soil is one of the most common reasons impatiens walleriana 'xtreme salmon' struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A free-draining, gritty mix dries too fast for impatiens walleriana 'xtreme salmon' — 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.
Using a sharp, fast-draining "houseplant" or cactus-leaning mix that lets impatiens walleriana 'xtreme salmon' dry out. It needs a moisture-retentive but still airy blend.
