Harvest Tips
Harvest flowers in early morning after dew dries but before heat stress, when petals are most crisp and flavorful. Cut blooms at the base of the stem. Use within a few hours of harvest for best quality, or refrigerate in a paper towel-lined container for up to 3 days. Only harvest flowers from plants grown without pesticides or fungicides. Remove stamens and pistils before eating unless specified otherwise. Harvest regularly to encourage continuous blooming.

- 🌱 Nasturtiums contain glucosinolates, compounds also found in cabbage and broccoli, and have been shown in some studies to have antimicrobial properties.
