Overview
'Blue Flame' (2004) is a sport of 'Fragrant Blue', noted in the registry as a "marginated 'Fragrant Blue'". Its leaf is intensely blue green with flat, creamy white margins .1 to .5 in (0.3 to 1.3 cm) wide, and carries a glaucous bloom on top and underneath.
In the Garden
It is registered at 16 in (40.6 cm) tall and 22 in (55.9 cm) across; habit and growth rate are not part of the entry. Leaves are 6 in (15.2 cm) long and 4.5 in (11.4 cm) wide, broadly ovate with a cordate base, lightly corrugated, with 8 vein pairs. Blue-green scapes are recorded at 16 in (40.6 cm).
How it compares
'Fragrant Blue' (1988), the parent, registered by P. Aden, has its leaf color entered only as "blue green". It is registered smaller, 8 in (20.3 cm) tall by 12 in (30.5 cm) across, with a 5 in (12.7 cm) by 3 in (7.6 cm) leaf and 5 vein pairs. Choose the parent for a leaf without the creamy white edge; 'Blue Flame' adds the margin on a larger registered plant.
'Sleeping Beauty' (1997), in the same show class, is also intensely blue green with a creamy white margin, .38 in (1.0 cm) wide, and shares the 16 in (40.6 cm) height on a 20 in (50.8 cm) spread. Its leaf is narrower, 6.5 in (16.5 cm) by 3.75 in (9.5 cm), with 10 to 12 vein pairs, and its scapes are recorded at 18 to 24 in (45.7 to 61.0 cm).
'Minuteman' (1994), a sport of 'Francee', has a dark green leaf with a wider .75 in (1.9 cm) creamy white margin. It is registered at 12 in (30.5 cm) by 24 in (61.0 cm), with green scapes of 18 to 30 in (45.7 to 76.2 cm).
