Chinese Crown Orchid: Invasive Species Identification Guide

In this guide

People often see a grassy plant with small greenish flowers popping up in mulch. They assume it is Bletilla, the well known Chinese ground orchid. In much of Florida, that plant is actually Eulophia graminea, commonly called the chinese crown orchid.

It is not something anyone planted on purpose. The chinese crown orchid is a naturalized, invasive terrestrial orchid. It spreads through mulch beds and disturbed soil on its own.

University of Florida records show it was first found in mulch in South Florida in 2007. Since then it has rapidly spread to thirteen Florida counties. This article explains what it is, whether it is a problem, and how to deal with it.

What a chinese crown orchid looks like

A chinese crown orchid grows from a pseudobulb that sits right at the soil surface. Each bulb looks like a small onion. Grassy, pleated leaves emerge from the top of every bulb.

New bulbs cluster together over time. They form a dense patch within a season or two. Left alone, a single plant can turn into a colony fast.

In spring, a tall bare spike rises straight up from the base. It carries many small greenish flowers, each with a pink lip and darker markings. A flowering plant can reach about a meter, or roughly 3 feet, tall.

The flowers are not showy compared to a typical potted orchid. That is one reason people miss the plant until it has already spread. By the time it gets noticed, a bed can hold dozens of pseudobulbs.

Common look alikes before it flowers

Before the flower spike appears, a chinese crown orchid looks like ordinary grass. The pleated blades sit low and blend into a mulch bed or lawn edge. Many people only notice it once the tall spike stands out.

By then the plant has usually formed several pseudobulbs already. A single clump can hide five or six bulbs under the soil surface. That underground spread is why pulling the visible leaves alone rarely works.

Is the chinese crown orchid invasive

Yes, it is. The Florida Invasive Species Council classifies it as a Category II invasive species. That ranking means it has increased in abundance across the state.

Category II does not yet prove it displaces native plants the way Category I does. Researchers are still tracking that impact. The trend line is still worth taking seriously.

This plant is native to tropical and subtropical Asia, not Florida. It does not appear on any list of Florida’s native orchids. Finding it in a mulch bed does not mean a native orchid is nearby.

It has now been documented from Brevard County south through the Keys. Its range also runs west into Collier, Lee, and Manatee counties. New counties get added most years as the plant keeps expanding.

How the chinese crown orchid spreads

  • Tiny, dust like seeds travel easily on wind, much like many other terrestrial orchids.
  • Seed capsules and broken pseudobulb pieces hitch rides in bagged mulch and topsoil.
  • Disturbed ground, construction sites, and freshly mulched beds give new seedlings an easy foothold.

This pattern explains why the plant shows up in yards before it reaches wild areas. Landscaping crews often move it without knowing. A broader ground orchids overview shows most terrestrial species spread far more slowly.

Which “Chinese orchid” do you actually have

Two very different plants share the nickname Chinese orchid. Mixing them up leads to bad advice either way. Use the table below to tell them apart before deciding what to do.

Feature Eulophia graminea Bletilla striata
Growth habit Pseudobulb at the surface, spreads on its own Stays where it is planted
Leaves Grassy, pleated, plain green Broad, pleated, variegated forms exist
Flower Small, greenish with a pink lip Larger, purple pink or white
Hardiness Naturalized in warm Florida climates Hardy outdoors in zones 5 to 9
Status Invasive, never sold on purpose Sold at nurseries as a landscape plant

Bletilla striata is the plant most people picture when they hear “Chinese orchid.” It behaves nothing like the invasive species covered on this page. If your grassy orchid stays in one clump, it is likely Bletilla instead.

Should you grow a chinese crown orchid on purpose

Honestly, no. The flowers are small and greenish, not the showy bloom most gardeners want. It already spreads on its own where conditions allow it.

Compare that to orchids people actually cultivate for bloom. A Phalaenopsis wants roughly 1,000 to 1,500 foot candles of light. Nighttime temperatures should stay around 60 to 65 F for that genus.

Cattleya needs roughly twice that light level to bloom well. A chinese crown orchid needs none of that attention. It thrives in bare mulch with no fertilizer and no temperature control at all.

That lack of demands is exactly why it spreads so easily. If you want an orchid that rewards real care, start with our guide to types of orchids. It points to genera that actually flower well indoors.

Feeding decisions matter more for orchids worth growing on purpose. A quarter to half strength dose from a balanced orchid fertilizer routine suits most potted genera during active growth. That kind of care is wasted on a weedy species you are trying to remove.

Some gardeners also ask which orchids tolerate an outdoor spot year round. Our page on whether orchids can live outside covers realistic options for a patio or garden bed.

Local extension offices track this species mainly through reports from home gardeners. A large patch in a natural area, rather than a yard, is worth reporting.

Your county extension office wants to know. That reporting helps track how far the range keeps expanding.

How to remove a chinese crown orchid

Timing matters more than technique here. Dig out the whole pseudobulb before the flower spike sets seed. A mature seed capsule can release thousands of dust like seeds at once.

  1. Dig several inches around the base to lift the entire pseudobulb, not just the leaves.
  2. Check the surrounding soil for smaller bulbs that have already split off the main clump.
  3. Bag everything, including any spent flower spikes, rather than adding it to a compost pile.

Do not till the area afterward. Tilling can chop pseudobulbs into pieces, and each piece can resprout on its own. One patch can turn into several within a season.

Recheck the bed every few weeks through spring. Missed bulbs will send up a new spike the following year. Persistence matters more than any single treatment.

Frequently asked questions

Is the chinese crown orchid the same as Bletilla?

No. Bletilla striata is a different species sold as a garden plant. The chinese crown orchid, Eulophia graminea, is an invasive Florida species nobody plants on purpose.

Where did the chinese crown orchid come from?

It is native to tropical and subtropical Asia. It was first found in mulch in South Florida in 2007 and has since spread widely.

Can you compost a chinese crown orchid after pulling it?

No. Bag the whole plant, including any flower spikes, instead of composting it. Seed capsules can still mature and release seed even after pulling.

Is it illegal to grow a chinese crown orchid?

It is not illegal to leave one growing, but nobody sells or plants it on purpose. It is listed as a Category II invasive species in Florida.

How can you tell a chinese crown orchid from ordinary grass?

Before it flowers, the pleated leaves do look like grass. A tall bare spike with small greenish flowers in spring is the giveaway.
