Star of Bethlehem: A Beautiful but Invasive Plant
Introduction
Star of Bethlehem is a winter bulb that blooms in late spring or early summer. It is native to the Mediterranean region and is similar to wild garlic. Its foliage has arching leaves but does not have the garlic odor when crushed.
Description
Star of Bethlehem flowers are small and star-shaped, and they rise on stems above draping foliage. The plant can quickly spread and take over when planted in beds with other ornamental bulbs.
Invasive Nature
Star of Bethlehem is considered an invasive plant in many areas. It can quickly out-compete native plant life and become a danger to their survival.
Uses
Star of Bethlehem is sometimes used as an ornamental plant, but it is important to be aware of its invasive potential. Some people believe it is best not to plant it at all, while others recommend growing it in containers or areas where it can be controlled.
Growing
If you decide to plant Star of Bethlehem, it is important to do so in fall. The plant is hardy in USDA Zone 3 with mulch and grows in Zones 4 to 8 without mulch. Plant the bulbs in a full to mostly sunny area of the landscape. They should be planted about 2 inches apart and at a depth of 5 inches to the base of the bulb.
Control
To prevent Star of Bethlehem from spreading, you can plant it in a buried container or an area that is lined and edged. You should also deadhead the flowers before seeds develop. If the plant becomes too prolific, you can remove the entire bulb to stop its growth.
Star of Bethlehem and Wild Garlic
Star of Bethlehem is often confused with wild garlic, but the two plants are not related. Wild garlic has a strong garlic odor when crushed, while Star of Bethlehem does not.
Star of Bethlehem in Alabama

Conclusion
Star of Bethlehem is a beautiful plant, but it is important to be aware of its invasive potential. If you decide to plant it, be sure to take steps to prevent it from spreading.
