Caring Tips for Recipient

  • Place in a cool, bright room away from direct midday sun and heat sources.
  • Refresh vase water and trim stems every one to two days.
  • They fade quickly if kept in warm rooms or left in cloudy, dirty water.

How to present as a gift

Keep arrangements rustic and airy—bundle loosely or place in a simple jar. Pair with meadow elements (grasses, daisies) and avoid heavy, perfumed companions. Remove lower foliage, recut stems, and note short vase life (about 3–5 days). Avoid gifting to anyone with known mustard allergy.

Ideal delivery time

Best in early spring when fields are in bloom; deliver in the morning and as fresh as possible after cutting.

  • From tiny seeds, great things grow—wishing you new beginnings.
  • Sending a little field of sunshine to lift your spirits.
  • May your season be bright and abundant.
  • Faith as small as a mustard seed can move mountains—cheering you on!
  • Here’s to growth, resilience, and brighter days ahead.

Things to Know Before You Gift This

Use this as a quick check if you’re gifting to a household with children or pets.

Mustard flowers and foliage are generally considered low in toxicity, but concentrated seeds and large amounts of plant material can cause mild digestive upset if eaten.

Risk areaLevelPractical advice
ChildrenMild risk if ingestedDiscourage children from chewing large quantities of seeds or raw plant parts and keep garden seeds stored out of reach.
PetsMild to moderate if ingestedPrevent pets from grazing heavily on plants or spilled seed, as this can cause stomach upset or discomfort.
Skin contactLow to moderateMost people tolerate casual contact, but those with sensitive skin should rinse off sap and wear gloves when handling large amounts.

If a child or pet swallows a large amount of seeds or develops worrying symptoms, contact a doctor or veterinarian for advice.

Helpful if you’re choosing for someone with fragrance or pollen sensitivities.

Mustard flowers usually cause few problems as short-lived garden or cut flowers, but sensitive individuals may react to pollen or to airborne dust from seed and foliage.

FactorLevelSuggestion
PollenLow to moderate outdoorsThose with strong hay fever should avoid placing flowering plants close to frequently opened windows or bedroom areas.
FragranceLight and generally unobtrusiveScent-sensitive people usually tolerate mustard flowers, but good room ventilation is still recommended.
Best placementBetter outdoors or in well-ventilated spotsKeep potted or cut mustard stems in airy spaces rather than small enclosed rooms for those with allergies.
* For severe respiratory allergies, it’s always best to follow the recipient’s own doctor’s advice.
