Frequently Asked Questions

How do I know when my Cactus Queen of the Night is about to bloom?

Watch for a slender bud swelling at the stem margins over several weeks. The flower typically opens in the evening and stays fully open for just a few hours overnight, so check in the late evening once a bud looks close to bursting.

Why has my Cactus Queen of the Night never bloomed?

Infrequent blooming is normal for this species even under good care — it may only flower once a year or so. Insufficient light, a root-bound pot, or lack of a cooler winter rest can delay flowering further.
