Spring Fever® Yellow Papaver

Spring Fever® Yellow is the yellow color selection in Syngenta Flowers’ Spring Fever series of Papaver nudicaule.

[Syngenta product detail](https://www.syngentaflowers.com/emea/product/flower/70004237) ## Seasonal display The yellow flowers rise on short stems above finely divided, gray-green foliage. The series can flower from spring into summer depending on sowing time; Syngenta’s production notes list spring flowering, with timing varying by crop schedule. This entry is the yellow selection, distinct from the mixed-color series product. ## Growing conditions Grow in full sun in well-drained soil. The Royal Horticultural Society describes Spring Fever as a short-lived perennial or biennial series suited to cool climates, with a typical height around 35 cm; Syngenta lists this color selection at 20–30 cm tall and 7–9 cm wide.

Water to establish and maintain evenly moist but well-drained soil. Avoid excess moisture around the roots, and treat the plant as a short-lived perennial or biennial rather than assuming a permanent clump.
