Lisianthus (Eustoma): colours, meaning, where it grows and when it blooms

Lisianthus, also called prairie gentian or Eustoma, is a small genus in the gentian family, wild in warm parts of Mexico, the southern United States, the Caribbean and northern South America. It grows on grassland and broken ground, carrying funnel-shaped flowers in pink, purple, white and blue, and is grown for the cut-flower trade.

What does Lisianthus look like?

Eustoma are herbaceous plants, meaning they have soft stems rather than woody ones, and they live for a single year. They stand 15 to 60 cm tall, though flowering plants are often given as 30 to 90 cm, with dwarf kinds reaching only about 200 mm. The leaves are bluish green and a little succulent, so they hold water. The flowers are large, funnel-shaped and sit on long, straight stems, either a single upright stem or a branching one. Each bloom can reach 50 mm across and comes in many shades of pink, purple, white and blue, with some bicoloured, and now and then yellow or carmine red.

Where does Lisianthus come from?

Wild Eustoma grows in the warm belt that runs through Mexico, the southern United States, the Caribbean and northern South America, on grassland and on broken, disturbed ground. The genus is small, holding only two or three species. Its scientific name comes from Greek: eu- means good or well, and stoma means mouth, so the whole word can be read as having a pleasing mouth. The older name Lisianthus was built from lissos, smooth, and anthos, flower. That name is now counted obsolete, yet people still use it. Eustoma russellianum is the species most often grown, and it has many named cultivars.

When and how Lisianthus blooms

Growing lisianthus takes patience. The seeds are tiny and must be pressed onto the surface of the soil rather than buried. The plants want rich soil that drains well, full sun, and steady moisture without being waterlogged; too much water encourages fungal disease. Temperature has to be watched, because the wrong conditions make the plant form a tight rosette instead of a stem, and growing under cover helps stop spots appearing on the petals. Flowering starts in early summer, and some plants keep going through the later summer months.

How Lisianthus is used

Lisianthus is grown as a cut flower, and a costly one: the trade treats it as a high-end bloom, sold for arrangements and bouquets. It is also planted in gardens for its summer flowers. The cut stems are valued for their staying power, holding their looks for two to three weeks in a vase. Most of what is sold comes from cultivars of Eustoma russellianum, bred and grown for the cut-flower market. Raising it for the trade takes attention, since the plant dislikes being overwatered and needs its temperature managed.

Kinds of Lisianthus

Flowers come in two forms, single and double, and both appear across the whole range of colours. Plants differ in height too: ordinary kinds reach about 30 to 90 cm, while dwarf varieties stop at around 200 mm, which suits pots and edges. The genus itself is small, with only two or three species, and Eustoma russellianum is the one taken furthest, with many cultivars selected for the cut-flower trade.

What Lisianthus means

The names carry the plant's history. Eustoma is Greek for a pleasing mouth, and the older Lisianthus means smooth flower; the pair has a long and confused record, with a third spelling, Lisyanthus, tangled in as well. Beyond the naming, the plant's standing rests on the flower trade, where it is counted a high-end cut flower, and on the patience it asks of growers, since it is regarded as tricky to raise from seed.

Is lisianthus easy to grow?

No. It is described as tricky and as needing maintenance. The seeds are tiny and must lie on the soil surface, not be buried, and the plants need rich, well-drained soil, full sun, steady moisture and careful control of temperature.

How long do the flowers last?

On the plant, blooming begins in early summer and in some plants carries on through the later summer months. Once cut, the stems keep for two to three weeks in a vase.

Why does it have two names?

Eustoma is the current genus name, from Greek words for good or well and mouth. Lisianthus is the older name, taken from Greek for smooth and flower, and though it is now counted obsolete it is still the name most people use.
