Harvest Tips

Fun Facts
- 🌱 Iris reticulata blooms so early it often flowers through snow, earning it the nickname 'Netted Iris' from the mesh-like veining on its bulb tunics.
- 🌱 The flowers are highly fragrant with a sweet, grape-like or violet scent, unusual for such a small flower, making them prized for perfumery and scented arrangements.
- 🌱 Unlike many irises, Iris reticulata naturally naturalizes and spreads over time in suitable conditions, creating stunning early spring drifts of color that return reliably year after year.
