Collapse ▲Trial: Perennial
Years Trialed: 2000, 2001
Good Qualities
Year 1
Uniform stem length, sturdy stems, happy color!, some rebloom (though shorter stems); Heleniums are diehards here and I really like that they can be potentially treated as annuals; Long vase life, great stem length, very popular fall/late summer filler, excellent production in latter years.
Year 2
Heavy branching; Yellow, tall; Excellent vase life, very productive.
Problems
Year 1
Bit of messy pollen shed after 5 days in the vase; Postharvest: Turns water with preservative cloudy in 1 day, not desirable cut flower; These are so easy to grow – but wind and toppling is a huge problem – so support is required to get a saleable crop; Can get too tall, can flush all at once – weed sequential pruning to stagger bloom.
Year 2
Seemed to have more trouble with lodging than some other heleniums; Very tall, cut back at 12; to keep below 4′, cut back immediately after first bloom, 2nd bloom in September at 29; possible.
