Sun Loving



Bright starry blooms cluster atop narrow leaves for a striking display of bold color and crisp form. Use solo as a centerpiece or arrange amongst a backdrop of foliage plants. Once flowering has ended, reduce watering to a minimum. Use caution when handling Ornithogalum dubium. All parts of the plant are toxic to humans, cats, and dogs. Wearing gloves is recommended when handling the plant for pruning or potting. Keep this plant out the reach of children and pets.


A great potted plant for a sunny window or table centerpiece. Makes a nice gift plant!

Sun Star, Orange Star Plant Indoors (Ornithogalum dubium) Care Guide

If the plant was purchased in a pot, then it is probably already in a quality potting soil and requires little more than watering and grooming for a while.

If potting a flowering plant to bring indoors or to give as a gift plant, start with a good quality, commercial potting soil. These are usually lighter in weight than topsoil, sterile and pest-free. Many are available with a mild starter fertilizer in the mix.

Select a container with a drainage hole or be prepared to drill holes for drainage if there are none.

Prepare the container by filling with potting soil up to 2” (5cm) from the rim of the planter. Make a small hole in the soil slightly larger than the root ball either by hand or using a trowel. Insert the plant into the hole and press soil firmly around the roots and just covering the root ball. When all the plants are potted, water thoroughly to settle the soil and give plants a good start. Place plant in bright location for best performance.

Repot every 2 years in the same container or in a container slightly larger than the diameter of the roots.

Most potted flowering plants prefer consistently moist but well-drained soil. If the soil gets too dry the blooms can wilt and they may not recover. Check the soil moisture with your finger. If the top 2-4” (5-10cm) of soil is dry, or plants are wilted, it is time to water.

Apply water at the soil level if possible to avoid wetting the foliage. Water the entire soil area until water runs out the base of the pot. This indicates that the soil is thoroughly wet.

Remove the flowers as they fade. This keeps the plant looking tidy and may encourage more blooms depending on the type of plant. After flowering many blooming plants make attractive houseplants. Be sure to trim the foliage to maintain the desired size and shape. Occasional trimming encourages the plant to develop more side-shoots and flowers, and reduces the demand for the plant to develop a larger root system. This is important since the roots are in a confined space.

Some plants will re-bloom on their own, but others may have very specific day-length or temperature requirements to flower again. A bit of research may be necessary to determine what is needed to encourage future blooming. Some plants, such as bulbs or perennials, can be turned into wonderful garden additions after the flowers have been enjoyed indoors.

Fertilizers are available in many forms: granulated, slow-release, liquid feeds, organic or synthetic. Determine which application method is best for the situation and select a product with a nutritional balance designed for foliage plants.

Too much fertilizer can damage plants so it’s important to follow the package directions to determine how much, and how often, to feed plants.

Slow-release fertilizers are an especially good, care-free choice for container plants. Follow the product directions for proper timing and application rates.

    I have a Sun Star plant, purchased in a pot. I will keep it indoors as I live in 6a. My concern is that there are four spikes that are flopping all over. The plant is very healthy, but I’d like to repot it, and wonder if it should be staked or cut back.

      Hi E.M.,
      You should stake the stems. If they continue to flop, it’s just a matter of time before the weight bends them to the point of causing damage or even breaking. The fact that they are flopping suggests that the stems may be stretching for light and becoming weak in the process. If possible, move your plant where it can get plenty of bright, indirect sunlight. If that’s not possible, supplemental lighting could be helpful.

    I was given a Sun Star Ornithogalum as a gift for mothers’ day. I love this plant and its color, but I had it on my patio in indirect light and when it stopped blooming it started to look sick. I want to revive it and move it into my house next to a sunny window. How do these plants propagate and how and what do I do to save it.

    • My Garden Life

      Hi Thurma,
      After flowering sun star naturally starts to die back and goes dormant for a while. To propagate your plant remove it from the pot and separate the bulbs. Plant them at a depth about twice the height of the bulb and at least 2” apart. Place the pot(s) by a bright window and water when the top 2” of soil is dry to the touch. New growth will eventually emerge and the plant(s) repeat the cycle of growth, bloom, and dormancy. If you live in a region with mild winters, you could plant your sun star bulbs in a sunny location outdoors. Apply a layer of mulch to provide extra protection in the winter, in case unexpectedly cold weather hits.

      Use caution when handling Ornithogalum dubium. All parts of the plant are toxic to humans, cats, and dogs. Wearing gloves is recommended when handling the plant for pruning or potting. Keep this plant out the reach of children and pets.
