This species is also unusual in its genus in including diploid, tetraploid and hexaploid races. The hybrids produced from it are often tetraploids.[2] AppearanceIt produces five tall flower spikes of yellow to scarlet flowers, often streaked red over a yellow ground color, generally with a yellow throat.[2] CultivationIt prefers a light sandy neutral to slightly acid soil with a pH between 6.5 and 7 in a sunny sheltered position and requires a stony gritty loam.
