Fun Facts
- 🌱 The name 'Fairy Duster' comes from the delicate, feathery appearance of the flowers, which look like tiny red or pink powder puffs that seem to float on the branches. The common name 'Powder Puff' refers to this same whimsical resemblance.
- 🌱 Calliandra flowers have a fascinating structure: the colorful parts are actually long stamens (male reproductive parts), not petals. The actual petals are small and inconspicuous, hidden beneath the showy stamens.
- 🌱 This plant is native to Mexico and is hardy enough to be considered semi-evergreen in zone 9b, sometimes retaining foliage through mild winters while remaining fully deciduous during harder freezes.
