Golden Shrimp Plant (Pachystachys lutea) blooms in bright light with some sunshine, warm and humid conditions and moderately moist, rich, well-drained, all purpose soil coupled with fortnightly feeding in the growing season.
Pachystachys lutea also called Yellow Shrimp Plant, Lollipop Plant or Candle Plant is among the upright, evergreen, popular flowering plants which bears a bright yellow spike from which white, two-lipped flowers emerge.
The spike is made up of bright yellow bracts and short-lived white two-lipped flowers which emerge sequentially. Yellow Shrimp flowers from spring through summer.
The common name, 'Shrimp Plant', is in reference to the layered (overlapping) bright yellow bracts which resemble a shrimp's layered scales.
The dark-green leaves in Golden Candle Plant are heavily veined which gives them a corrugated appearance. The inflorescence are held upright on long stalks above the dark-green foliage.
Pachystachys lutea is similar to Beloperone guttata (Mexican Shrimp Plant) which features bright reddish-yellow bracts instead of bright yellow bracts.
Botanical name: Pachystachys lutea
Family: Acanthaceae
Common names: Golden Shrimp Plant, Yellow Shrimp Plant, Lollipop Plant, Golden Candle Plant
Origin
Pachystachys lutea is native to the subtropical regions of Peru.
Size
Golden Shrimp Plant can grow to a height of about 3-6 feet.
Toxicity
A Research directed by C. Daehler (UH Botany) indicates that Pachystachys lutea is toxic to animals and causes allergies or is otherwise toxic to humans. Keep it away from the reach of children and pets. Always wear gloves when handling the plant.
Pachystachys lutea Care Indoors
Golden Shrimp Plant (Pachystachys lutea) blooms in bright light with at least 4-6 hours of sunshine, average warmth of 15-280C, humidity of 60-70% and moderately moist, rich, well-drained, all purpose soil coupled with fortnightly feeding during the growing season.
Pachystachys lutea requires regular grooming to keep it neat and annual cutting back to rejuvenate growth. Annual repotting is needed for the young plants while the mature plants require annual top-dress of the soil. Keep reading for more on these growing conditions and how to provide them.
Light Requirements
Golden Shrimp Plant grows best in bright light with 4-6 hours of morning or evening sunshine but too hot sunshine will scorch the leaves.
If light is not enough for Yellow Shrimp Plant, it will become leggy with wide spaces between the leaf nodes and will not bloom. Therefore, you may grow the plant under a grow light where the natural light is not sufficient. Check out these full spectrum grow lights on Amazon.
Turn the pot regularly to ensure the plant receives light on all sides for even growth and prevent leggy growth.
Golden Candle Plant can also be grown outside under direct sunshine but it needs to be acclimated gradually before being exposed to direct sunshine to avoid sunscorch.
Watering
Water Golden Shrimp Plant thoroughly during the growing season while allowing the top 1-2 inches of soil to dry out between waterings and keep the soil consistently moist through out.
Reduce watering during the cold season to maintain the soil slightly moist as growth is minimal at this time. Do not allow the soil to dry out as it can lead to wilting and leaf drop.
Ascertain that the soil is free-draining and the pot has a drainage hole to avoid getting soggy soil as it can result in root-rot and loss of the plant.
Temperature and Humidity
Average room temperature of 15-280C is ideal for Golden Shrimp Plant. Keep it away from drafty conditions as cold temperatures can cause stunted growth and leaf drop.
Average to above average humidity of 60-70% is ideal for Golden Shrimp Plant. The plant thrives in warm, humid conditions like in its natural environment. Too low humidity will lead to brown leaf tips and edges. To increase humidity especially where the room temperatures are very high, set the pot on a wet pebble tray or use a cool mist humidifier. Read more on how to elevate humidity for houseplants.
Occasionally clean the leaves by damp-wiping with a soft cloth to get rid of dust as well as discourage pest and disease infestation. Ensure that there is good ventilation to minimize fungal diseases.
Fertilizer
Feed Golden Shrimp Plant with a phosphorous-rich, water-soluble fertilizer every 2-3 weeks during the growing season to promote flowering. Do not feed in the cold season as growth is minimal at this time and feeding at this time can cause fertilizer burn.
Potting Soil
The best soil for Golden Shrimp Plant should be rich in organic matter and free-draining to prevent it from getting soggy while providing the required nutrients. All purpose potting mixes are ideal for this plant.
Repotting
Repot the young Golden Shrimp Plant at the beginning of the growing season into a pot one size larger than the current one. Ensure that the pot has a drainage hole and the soil is free-draining soil to avoid getting soggy soil as it can lead to root-rot. Take a look at these pots with drainage holes on Amazon.
Do not repot a plant that is in flower as the repotting shock can shorten the flowering period. The large plants can be top-dressed annually at the beginning of the growing season by replacing the top 3-4 inches of soil with fresh soil.
Pruning
Prune Golden Shrimp Plant by removing dead blooms and leaves to maintain the plant neat as well as discourage pests and diseases infestation. Cutback the stems at the beginning of the growing season to rejuvenate growth as the plant becomes straggly and unattractive with age.
Propagation
Golden Shrimp Plant (Pachystachys lutea) can be propagated at the beginning of the growing season from stem-tip cuttings.
How to propagate Golden Shrimp Plant from stem-tip cuttings
Take a 4-6 inches stem-tip cuttings from a healthy Golden Shrimp Plant. Strip off the lower leaves of the cuttings and coat the lower part of the stem with a rooting hormone.
Carefully insert the coated cuttings in moist, free-draining soil and ensure the rooting container has adequate drainage holes to prevent the soil from getting soggy as it can lead to rotting.
Cover the set up with a clear plastic bag or sheet to create a greenhouse effect to hasten rooting. A warm and humid environment is needed for rooting to happen.
Place the set up in bright light but away from direct sunlight to avoid cooking the cuttings.
Maintain the soil moist through out until the cuttings are rooted. Rooting should occur in about 6-8 weeks and is indicated by new growth.
Once rooted, remove the plastic cover a little every day over a period of 2 weeks to acclimate the new plants to normal indoor growing conditions.
Allow the new Pachystachys lutea to be well established before transplanting after which you can begin routine care.
Pachystachys lutea Problems
Golden Shrimp Plant (Pachystachys lutea) problems include drooping leaves, lack of blooms, brown leaf tips, pests and diseases among others. Keep reading for more on these problems and how to fix them.
Pests
The common pests in Golden Shrimp Plant are mealy bugs, scales, aphids, whiteflies and spider mites. Isolate the affected plant to prevent spread to the other plants and treat it for the pests. Learn how to identify and control houseplants pests.
Wilting and droopy leaves
Underwatering is the cause of wilting and droopy leaves in Golden Shrimp Plant. Water the plant thoroughly during the growing season while allowing the top 1-2 inches of soil to dry out between waterings to maintain the soil moist. Decrease watering in the cold season to keep the soil slightly moist but do not allow the soil to dry out completely. Learn more on how to water indoor plants the correctly.
No blooms
The are three possible causes of lack of blooming in Golden Shrimp Plant. One possible reason is too little light. Move the plant to a brighter spot where it can receive bright light with 4-6 hours of morning or afternoon sunshine or instal a grow light if the natural lighting is not adequate. Check out this guide on understanding light for houseplants.
The second possible reason why Golden Shrimp Plant will not bloom is feeding it with a nitrogen-rich fertilizer which promotes foliage growth at the expense of flowering. Feed the plant with a phosphorous-rich, water-soluble fertilizer every 2-3 weeks during the growing season to promote flowering. Read on how to feed houseplants.
The third possible reason why Golden Shrimp Plant is not blooming is underwatering. Water the plant thoroughly during the growing season and keep the soil moist through out. However, cut down on watering in the cold season to maintain the soil slightly moist but do not allow the soil to dry out completely.
Brown leaf tips and edges
Two reasons are responsible for brown leaf tips and edges in Golden Shrimp Plant. One reason is dry air (low humidity). Set the pot on a wet pebble tray to raise humidity or grow the plant in a well-lit bathroom, kitchen, laundry area and other moist areas in the home.
The second reason for brown leaf tips and edges in Yellow Shrimp Plant is soggy soil. Maintain the soil moist but not soggy by ensuring that the pot has a drainage hole and that the soil is free-draining (drains easily).
