4-6 weeksNewly planted divisions or transplants develop roots and produce initial foliage shoots
Keep soil consistently moist for 4-6 weeks; apply 2 inches of mulch around base; do not fertilize heavily

Spring through early summerPlant develops its characteristic mounding habit with upright, arching green foliage
Water during dry periods; light feeding in spring with balanced fertilizer; thin out dead foliage from previous year
Flowering
Late August through OctoberFeathery, reddish-bronze plumes emerge above the foliage canopy
Do not deadhead if you want seeds for birds; allow plumes to develop fully for best ornamental effect
Dormancy & Winter Color
November through FebruaryFoliage fades to bronze-gold, plumes persist and dry out; plant goes dormant
Cut back to 4-6 inches above ground in late winter (February-March); do not cut back in fall as dried foliage provides winter interest and protection

Fun Facts
- 🌱 Dwarf fountain grass is often confused with pink muhly grass, but 'Hameln' is hardier, more compact, and blooms earlier in the season (late August vs. October).
- 🌱 The plumes can persist on the plant through winter, creating a shimmering effect in frost or ice that catches light beautifully.
- 🌱 This grass is relatively sterile and self-seeds minimally, unlike some other ornamental grasses, making it a good choice for areas where you want to prevent volunteer seedlings.
