Ageratum--Floss Flower

Floss flower has fluffy looking flowers and can be
used for edging or in containers. The taller cultivars may
be used as cut flowers. Other uses are in rock gardens or
as a winter house plant. Ageratum grows in well drained,
medium rich soil and does not tolerate dryness. Provide
full sun or partial shade and remove the old flowers to
promote continuous blooming. Floss flower dies at the first
frost. Plants are 6 to 12 inches tall depending on
cultivar.

Seed can be planted inside or in the garden. Do not
cover ageratum seed as light is needed for germination.
Germination occurs in 5 to 10 days at temperatures between
70 and 75 degrees. Pinch seedlings to encourage branching.
Plant ageratum 10 to 12 inches apart.
