An orchid keiki is a small plantlet the mother plant grows on its own, usually on a flower spike or a cane. The word comes from Hawaiian and means “baby.” A keiki grows its own leaves, then later its own roots.
What an Orchid Keiki Looks Like
An orchid keiki starts as a tiny cluster of leaves at a node. The node sits on a flower spike in Phalaenopsis, or on a cane in Dendrobium. At first it looks like a bump under a papery bract.
A keiki is easy to confuse with a new flower spike or a root. A new spike is flat and pointed, and it grows upward from the base or a node. A root is round, smooth, and grows straight down with no leaves.
Some nodes send out a single root with no leaves at all. This is not a keiki, and it will not grow into a separate plant. Leave it in place, since it still helps feed the spike or cane.
A keiki grows leaves first, then roots weeks or months later. If the growth has leaves, it is a keiki. If it is flat and pointed with no leaves, wait to see if it opens into a spike.
Keiki vs New Spike vs Root
These three growths get confused often, especially on Phalaenopsis. Here is how to tell them apart at a glance.
| Growth | Shape | Direction | What Grows First |
|---|---|---|---|
| Keiki | Small cluster with leaf tips | Outward from a node | Leaves, then roots |
| New spike | Flat and pointed | Upward | Buds along its length |
| Root at a node | Round and smooth | Downward | No leaves at all |
Why Orchid Keikis Form
Keikis form when a hormone called cytokinin builds up at a node instead of triggering a flower. Warmth and high humidity favor keiki growth over spike growth. Some hybrids, especially certain Dendrobium types, are simply prone to it.
Stress is a common trigger too. Root loss, inconsistent watering, or heat stress can trigger one instead of a bloom. Read this as a signal: check the roots and watering routine, not just the keiki itself.
Treat a keiki as information, not just a surprise. If the plant lost roots recently or dried out for weeks, the keiki confirms that stress happened. Fix the growing conditions so the mother plant does not repeat the pattern.
A dying or badly stressed mother plant will sometimes push out a keiki as a last effort to reproduce. If the mother has few healthy roots or shriveled leaves, treat this keiki as a backup plan.
Orchid Keiki Stages and Timeline
Most keikis follow a similar pattern, though the pace varies by genus and conditions. Here is a general timeline for a Phalaenopsis keiki.
| Stage | What You See | Typical Timing |
|---|---|---|
| Bud swell | A node swells under its bract | Weeks 1 to 4 |
| First leaves | Two tiny leaves emerge | Weeks 4 to 10 |
| Leaf growth | Two to three leaves, no roots yet | Months 2 to 6 |
| Root emergence | First roots appear, still short | Months 4 to 9 |
| Ready to remove | Two to three roots, 2 to 3 inches long | Months 6 to 14 |
Dendrobium cane keikis often move faster once they start, sometimes reaching removal size in 4 to 6 months. After you pot the keiki, expect its first bloom in about 2 to 3 years.
When and How to Remove a Keiki
Many care pages say to remove a keiki as soon as you see a root. That advice comes too early. A single short root cannot support the plant once it is cut away from the mother.
Wait until the orchid keiki has two to three roots, each 2 to 3 inches long. It should also have two to three leaves of its own. Removing it earlier often kills it.
Check the roots before you cut. Green or silvery white tips mean active, healthy roots. Brown, mushy, or bone dry roots are not ready to support the keiki alone.
- Sterilize scissors or a blade with rubbing alcohol or a flame.
- Cut the keiki free about half an inch from the node, leaving a small stub on both sides.
- Let both cut surfaces dry for a few hours; some growers also dust them with cinnamon, though a clean, dry cut matters more.

When to Leave a Keiki Attached
Removal is not always the right move. If the mother plant is weak, an attached keiki can draw resources at a bad time. Leave it in place until the mother plant regains some strength.
Dendrobium canes sometimes produce several keikis at once. If the cane still carries healthy leaves, leave the smaller keikis attached and remove only the largest, most rooted one.
A keiki left attached through winter will often pause its growth. That is normal, and growth resumes with warmer weather and longer days in spring.
Potting and Caring for a New Keiki
Choose a small pot, just big enough for the roots with a little room to grow. Fine fir bark, sphagnum moss, or a bark and moss mix all work well for a young keiki.
Set the keiki so the base sits at the surface, not buried. Water it in, then let the top layer dry slightly between waterings. Bright, indirect light and 60 to 70 percent humidity help it settle in.
Many new keikis fail from rot, not from cold or low light. Keep the mix barely moist until you see active root growth. A clear bag or humidity tent over the pot for the first few weeks helps new roots establish.
Skip fertilizer for the first few weeks. Once you see active new root growth on the orchid keiki, feed at quarter strength every other watering. For repotting once it outgrows this first pot, see our step by step repotting guide.
Does Keiki Paste Work
Keiki paste contains a cytokinin hormone. It can nudge a dormant node toward making a keiki instead of staying inactive. It only works on nodes that have not yet committed to a flower or gone fully dormant.
Once a node starts forming a bud, paste will not change its path. Results vary by plant, node position, and timing, so treat it as a nudge, not a guarantee. For full instructions on application and timing, see our keiki paste guide.

Most growers reach for a small tube such as rePotme KeikiGrow Plus Keiki Paste. Apply a thin layer directly to an exposed node.
Dendrobium Keikis vs Phalaenopsis Keikis
Phalaenopsis keikis grow at a node on the flower spike, usually after blooming or when a spike stays green. See our guide to the orchid flower spike for more on spike care and reblooming.
Dendrobium orchids form keikis along the cane, often near the top, and sometimes several on one cane. This is common in nobile type Dendrobiums. It often follows a skipped winter rest or overwatering during that rest period.
Cattleya and Oncidium keikis are rare but can appear at the base of a pseudobulb under stress. Vanda keikis are uncommon and usually signal a struggling root system in the crown or lower stem.
Paphiopedilum and Cymbidium rarely form true keikis at all. Instead they multiply by dividing at the base, which is a separate process from cutting a keiki. For general Phalaenopsis care, see our phalaenopsis orchid care guide.

Frequently asked questions
How long does it take for an orchid keiki to root?
Most Phalaenopsis keikis take 6 to 12 months to grow roots long enough to remove. Dendrobium cane keikis can be faster, sometimes 4 to 6 months.
Can I remove a keiki with no roots?
You can pot a keiki with very short roots, but it needs closer humidity and moisture control. Waiting for 2 to 3 inch roots gives it a far better survival rate.
Will removing a keiki hurt the mother plant?
No, a clean cut with sterile tools does not harm a healthy mother plant. If the mother is already stressed, focus on her care first.
Does every orchid grow keikis?
No. Some plants never produce one, while certain Dendrobium hybrids produce them readily. Genetics, stress, and growing conditions all play a role.
How do I get an orchid to produce a keiki on purpose?
Keiki paste applied to an active node can encourage one to form, though results are not guaranteed. Warm, humid conditions also favor keiki growth over new spikes.
