Brilliance Autumn Fern questions
Is Brilliance Autumn Fern evergreen?
It's evergreen in milder climates (roughly zones 7-9) and semi-evergreen toward the colder end of its range (zones 5-6), where fronds may brown or flatten over winter.
Does it need shade?
Yes, it performs best in part to full shade; it can tolerate more morning sun in cooler climates if soil moisture is kept consistent, but afternoon sun in warm regions tends to scorch the fronds.
Is it toxic to pets?
It is not known to be toxic to pets or people, though as with any plant it's best to discourage pets from chewing on it.
How do I propagate it?
Divide established clumps in spring; this is far more reliable for home gardeners than growing from spores.
Why is the new growth reddish instead of green?
That's a hallmark trait of the cultivar — new fronds unfurl in coppery-red/bronze tones before maturing to dark green over a few weeks.
