White Mistflower

Ageratina havanensis

White mistflower is perennial shrub that grows 2’ – 4’ tall and 2’ – 3’ wide. It
produces ageratum-like clusters of fragrant, pinkish-white blooms in the fall that
are popular with butterflies. It grows in full sun but might appreciate some
shade in the late afternoon.

Planting Sites: White mistflower will grow in sand, loam, clay, or limestone soils. It needs good drainage and is
drought tolerant once established.

Planting Instructions: Dig hole slightly larger than, but the same depth as, the nursery container. Carefully remove
plant from container, gently loosen any compacted soil or circling roots around the root ball. Plant slightly higher
than the surrounding soil. Add 2 to 3 inches of mulch.

Watering Instructions: Water deeply after planting, using a root stimulator mixed according to directions. For
about 3 months, water deeply when top 2 – 3” of soil is dry to promote deep roots that will withstand drought. Skip
a watering after a rainfall of ½” to 1”.

Comments: Nectar source for butterflies and hummingbirds. Cut back severely each winter for best bloom and
attractive plant. Host plant for the Rawsons Metalmark butterfly. Moderately deer resistant.
