Trial: Perennial
Years Trialed: 1999, 2000Good Qualities
Year 1
The few flowers that I got were rather pretty; Jury still out. Grew well; Plants left have filled in nicely and only show little burn from heat.Year 2
Great vigor, easy, large heads; Much more vigorous 2nd year, therefore, foliage and stems are extremely nice.Problems
Year 1
Perhaps it was the drought or maybe they didn’t like being transplanted but they never did do very well. Seemed to be very weak and they flopped on the ground. Maybe I should have staked them; Powdery mildew; Flower is inconspicuous. Deer love this one.Year 2
All of the ones I ended up with flowered white; colors are more exciting; Very unimpressive flower, poor color, very poor yield.Year 2
Similar to Thalictrum delavayi and Thalictrum delavayi 'Hewitt's Double'; Must pick just before flower open; to pick later reduces vase life 2-4 days, oasis preservative lasted 9 days, in plain water, lasted 7 days; All species and cultivars appear uneconomic by the few cuttable stems produced.Trial Data

|---|---|---|---|---|---|
| Average | 2.0 | 17.0 | 1.3 | 1.7 | 3.3 |
¹Data shown are from those respondents who harvested stems. Some respondents may not have harvested stems because they were too short. Flowering stems may be longer next year after plants are established. See comments section for more details.
²1 to 5 scale, with 5 being the best. Market ratings are based on sales to wholesalers, retailers, or final consumers direct.

Comments
Year 1
Has similar foliage to Columbine; I really like the Thalictrums and maybe they will do better next year; May require vernalization. Probably should be fall planted (in California); May get better in future years; All survived, just didn’t flower yet, am optimistic about future.
