Care Guide
Keep soil consistently moist but not soggy during active growth and blooming.
Apply a very light, low-nitrogen organic feed if soil is extremely poor.. This species thrives in low-nutrient environments; excessive fertilization will harm it.
Eggshell Tea：Crush clean, dried eggshells and steep in water for 3-4 days. Strain and use the water to provide gentle minerals without overloading this low-nutrient alpine plant. Avoid high-nitrogen materials.- Deadheading: Remove spent flowers if you wish to tidy the plant, but leave some if you want it to self-seed.
- End of Season: As a biennial, the plant will die after setting seed; clear away dead debris in late autumn to prevent rot.
Toxicity
