Overview
'Firestorm' was registered in 2007 by K. Ziarek of Delafield, Wisconsin, as a sport of 'Prairie Fire'. The leaf is small, 5 in (12.7 cm) by 3 in (7.6 cm), yellow with a narrow medium green margin of 0.1 to 0.2 in (0.3 to 0.5 cm), lightly folded and wavy, with glaucous bloom on both surfaces. The registrant's note explains the color: it emerges green and turns an intense gold, leaving a green edge, which the record classes as a lutescent center.
In the Garden
The plant is registered at 25 in (63.5 cm) across and 18 in (45.7 cm) high with a moderate growth rate. Because the gold develops after emergence, the spring look differs from the summer one.
How it compares
'Prairie Fire', the parent, is an all-gold plant: deep gold leaves, dull on top, on a semi-upright clump registered at only 12 in across and 13 in high. 'Firestorm' adds the thin green margin and was registered as a wider mound.
'June Fever' sits in the same show class with a golden yellow leaf and a 0.2 in dark green margin, nearly the same edge width. Its seasonal change runs in the opposite direction: the center becomes chartreuse by midsummer, whereas 'Firestorm' gets brighter. The 'June Fever' registrant also noted sun tolerance, which the 'Firestorm' record does not claim. Its clump is registered at 29.5 in across and 15 in high.
'Rainbow's End', in the same class, was AHS Hosta of the Year for 2021 and Benedict winner the same year; 'Firestorm' has no award in the lists we checked. 'Rainbow's End' is registered at 21 in across with a slow growth rate, with a center that moves from yellow to creamy white and a much wider green margin, plus red scapes.
Flowers and other notes
Near-white flowers are recorded from July 15 to August 15 in Delafield, Wisconsin, but no scape height or seed information is given. The registrant notes that the leaves emerge green and turn an intense gold. General care is in the hosta care guide.
