Plant Profile: Crinum

Crinums are stunning summer-blooming bulbs that have adorned Southern gardens for many years. They evoke a sense of nostalgia while introducing a charming tropical flair to outdoor spaces. Their glossy, upright leaves create a striking contrast against more delicately textured plants.

As a member of the amaryllis family, crinums are among the more resilient bulbs, capable of withstanding temperatures as low as 25 degrees Fahrenheit (2 degrees Celsius). They can be safely cultivated in the eastern parts of our mountainous regions. For those residing in the western areas of North Carolina, crinums can be grown in pots that can be brought indoors during the winter months. The ideal planting period for crinums is from April through late October. They flourish in sunny spots with moist soil or in areas with filtered shade. If you're seeking plants suitable for woodland shade gardens, consider C. moorei.

Newly planted crinums require a season or two to establish themselves before they start to bloom profusely. They prefer not to be disturbed. After the initial flowering season, it’s beneficial to apply a high-phosphorus fertilizer in mid-May each year. Ensure they receive ample water during dry spells while they are in bloom. After four to five years, you can remove the offsets and replant them to expand your collection or share with fellow gardening enthusiasts.

NOTE: Consuming crinums may result in low toxicity.
