Robert Swanson Oriental Trumpet Lily
Robert Swanson Oriental Trumpet Lily (Orienpet Lily)
Oriental Trumpet Lily ‘Robert Swanson’ is one of our favorite Oriental Lilies, with its big striking red blooms (up to 7"), edged in a buttery yellow. Its light-green stigmas add another layer of contrast for a mid to late summer show that’s perfect in your perennial plant bed. Long-lasting and sweetly fragrant, the flowers (up to 40 per bulb!) make lovely cut flowers as well as pollinator friendly additions to the garden.

USDA Hardiness Planting Zones
To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.
- If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
- If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
