Peruvian daffodil 'Zwanenburg'

Keep in mind when planting that Zwanenburg is thought of as tender, so it is really important to ensure that the outside temperature is well above freezing before planting or moving outdoors.

Soil temperature should be kept higher than 16°C / 61°F to ensure good germination.

Ensure that temperatures are mild and all chance of frost has passed before planting out, as Zwanenburg is a tender plant.
