Catnip flowers are largely creamy-white or pink, clustered in spike-like racemes. Each flower is small (1/3-1/2") and has two unequal lips. The upper lip has two tiny lateral lobes, is smaller than the lower, and wider than long; the three-lobed lower lip is much larger, is longer than wide, has pink or purple spots, and has a frill on the lip of the middle lobe. The four stamens have anthers that are dark purple; the style protrudes just beyond the upper lip and has a bifurcated tip (the stigma). The fruit is four one-seeded nutlets nestled in the persistant calyx.
