Abstract:

Coastalplain honeycombhead (Balduina angustifolia) is a southeastern USA native wildflower with ornamental and pollinator value and limited horticulture information. We investigated its cutting propagation, stock plant feasibility, and landscaping performance (growth, visual quality, and flowering). While auxin was not needed to achieve .80% rooting percentages, application of 5,000 ppm IBA to cuttings improved rooting performance compared to cuttings treated with 0-2,500 ppm IBA. Photoperiod affected stock plant growth but not flowering, indicating photoperiod may be used for stock plant management as a source of cutting material. Cutting performance was improved in a peat-based mix compared to a 1:1 mix of perlite and vermiculite. In landscape trial 1 (testing effect of planting site), there was a low visual quality rating for plants installed in south Florida while plants in northwest and central Florida had higher visual quality (3 to 4 of the 7 months had a rating 3 out of 5). For landscape trial 2 testing the effect of population, there was high visual quality (3 of the 6 months had a rating 3 out of 5) for plants collected from all 3 populations, though there was a trend of reduced visual quality for plants from Navarre Beach compared Archbold or Bok Tower.
