Click on terms for botanical definitions.



Marsh gentian is an annual herbaceous wildflower found sporadically throughout the state. Its showy flowers are comprised of bright bluish-purple petals (sometimes white) with dark purple bases. Petals are fused at the base, forming a cup or bell shape with a dark throat. Leaves are elliptical to ovate, sessile and clasping. They are oppositely arranged. Stems are smooth and erect. Seeds are born in a sticky capsule.



Marsh gentian may bloom year-round, but typically blooms in the winter, spring and into summer. It occurs in salt marshes, beach dunes, coastal flats and moist prairies.



Marsh gentian is also known as seaside gentian and catchfly prairie-gentian.



The genus name, Eustoma, comes from the Greek eu, or “good,” and stoma, or “mouth,” and refers to the wide “mouth” of the corolla. The family name, Gentianaceae, refers to the Illyrian King Gentius (181-168 BC), who was thought to have discovered tonic properties in a species of gentian.
