Briiliant red flowers with a hint of orange can cover the low mounds of fresh green foliage. The first flush appears in early summer and the plant can produce flowers all summer. Eventually it can look tired and tatty but a quick trim back to an inch or two above ground and it will soon restart flowering on fresh growth - we often dispatch plants that have been freshly cut back.
Like all Mimulus it enjoys moist soil and a slighly cooler spot so is happy in a bit of shade but will flower abundantly in full sun as long as it doesn't dry out. About 7 cm (3") high.
'Whitecroft Scarlet' is an old variety becoming less and less common; not because it has faults, but due to newer, seed-raised varieties (much cheaper and easier for the nurseryman) overtaking it, especially all the 'Highland' ones (Highland Red, Highland Rose etc.) but we have never found them as truly perennial as 'Whitecroft Scarlet'.
