Cosmos Bipinnatus ‘Early Wonder’

Trial: Annual

Years Trialed: 2001

Good Qualities:

Colors/good color range (3); Prolific producer (3); multi-petals on flowers; Strong stems; Bright daisy flower, good height; Some of my customers loved it and others won=t buy it; Looked great out in the field, not a lot of interest from buyers though, Zone 2 – still looks wonderful Sept 25th!; Very dependable cut flower, use a lot of this cultivar in mixed bouquets, no deer damage (as opposed to Cosmos >Bright Lights=); Did very well in spite of no rain; Very hearty – kept producing until I mowed the bed – my other cosmos in the bed had stopped, but it was still producing.

Problems:

Short vase life of 3-5 days (3); Difficult to decide when to harvest as 1st flower or as a spray; Few problems, need to be careful on cutting; cut buds early to avoid shatter; Easily bruised flowers; Aphids; Quite tall – some wind (blown down) damage, late in the season, these are not staked.

Comments:

Started out as a problem, but ended as a success, we seeded in the greenhouse but far too early — so pinched the crop twice before setting out, plants out in the field were 32 ft tall and many very strong breaks; Similar to Purity, Sensation, Dazzler, and Combo; Some powdery mildew late in growth cycle, but not significantly more than other cultivars; Planted too late – short day plant, got lots of plant but little flowering. Light to deep pink, have been harvesting 1st bloom; Good in combination with >Early Wonder=, extends the Cosmos bloom.
