How to Grow Orange Ornithogalum Flowers

Fill a container with well-drained potting soil, leaving 1/4 to 1/2 inch between the top of the soil and the rim of the pot. The size of the container depends on how big the bulbs are and how many will be in the container. Choose a pot that is larger in diameter than the depth and will permit the recommended space between each bulb.

Plant the bulbs depending on when you want blooms. For December flowers, plant the bulbs in September. For February flowers, start the bulbs in mid-October. If the bulbs are started in mid-November, the plant will flower in March or April.

Examine the bulb to find the top. Plant with the pointed end facing up and the flat end, or the root section, facing down. Plant orange ornithogalum bulbs 1 inch into the soil and space each bulb 2 inches apart.

Water the soil thoroughly, or until the water comes out of the drainage holes at the bottom of the pot.

Store the pot of orange ornithogalum bulbs in a cellar or basement for eight to 12 weeks. When the leaves begin to push upward, bring the pot out of the basement or cellar.

Place the pot into a sunny location where the temperature remains around 65 to 75 degrees Fahrenheit.

Water the orange ornithogalum flowers to keep the soil moist but not soggy. Remove the spent flower spikes at the base of the plant. As the leaves begin to die back, reduce watering and allow the soil to dry as it prepares for dormancy.
