Finding Eustoma

It fascinates us that such a widespread native like Eustoma exaltatum isn’t more widely grown in gardens. Often known by the common names prairie gentian or lisianthus, eustoma is prized by flower arrangers, but not gardeners. Eustoma is native from coast to coast…Florida to California, and north to the Canadian border in Montana.

In the wild, Eustoma exaltatum is a short-lived perennial that can also behave as a biennial or even an annual in some sites. The key is to plant it where it can happily reseed as we have done in our gravelly crevice garden, which is odd, since in the wild, they are found in moist meadows and streamsides.

Below are our plants in peak flower now, during the brutal heat of summer. So far, we’ve struggled to keep this happy in a container, in the hopes we could make this available, but we continue to try.

Commercially, eustoma has been hybridized ad nauseam to create better cut flowers, but these hybrids seem to have lost all of their perennial nature compared to the wild genetics. Our plant pictured below is the large (2′-3′ tall) subspecies russellianum from wild collected seed from Bastrop County, Texas.
