Abstract

A new and distinct cultivar of Baptisia plant named ‘PIIBAP-06-21’, characterised by rich indigo flowers that are held upright and contrast exquisitely with the yellowish green foliage. There are no other cultivated Baptisia exhibiting these characteristics known to the invention.

Description

Genus and species of plant claimed: Baptisia hybrid.

Variety denomination: ‘PIIBAP-06-21’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of hybrid Baptisia, hereinafter referred to by its cultivar name ‘PIIBAP-06-21’. This cultivar is grown primarily as an herbaceous perennial for landscape and cut flowers. This cultivar originated from an open pollination of Baptisia x variicolor ‘Twilite’ (U.S. Plant Pat. No. 19,011) in Watkinsville, GA in 2019, and was selected from the progeny by continued evaluation for growth habit, floral, and foliage characteristics.

‘PIIBAP-06-21’ has been asexually reproduced by softwood cuttings since 2021 in Watkinsville, GA. The characteristics of the cultivar have been stable and reproduced true-to-type in successive vegetative generations.

SUMMARY OF THE INVENTION

‘PIIBAP-06-21’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with changes in light, temperature, soil and rainfall without, however, any variance in genotype.

The following traits have been observed and represent the characteristics of the new cultivar. In combination, these characteristics distinguish ‘PIIBAP-06-21’ from all other varieties in commerce known to the Inventors. 1) Rich indigo flowers are held upright and contrast exquisitely with the yellowish green foliage. 2) Produces abundant flowers and stems with numerous flowers. 3) Strong stems holding inflorescence vertical. 4) Columnar shaped plant habit becoming more vase-shape as foliage develops.

PARENTAL COMPARISON

‘PIIBAP-06-21’ is distinguished from its parent plant Baptisia x variicolor ‘Twilite’ (U.S. Plant Pat. No. 19,011) by leaf and leaflet color. ‘PIIBAP-06-21’ has yellowish green foliage, whereas ‘Twilite’ has green foliage. ‘PIIBAP-06-21’ has rich indigo flowers, but ‘Twilite’ has violet flowers.

COMMERCIAL COMPARISON

‘PIIBAP-06-21’ can be compared to the cultivar ‘White Gold’ (unpatented). ‘White Gold’ has chartreuse golden foliage with spikes of creamy white flowers. ‘PIIBAP-06-21’ has yellowish green foliage with rich indigo flowers. The flower spikes of ‘PIIBAP-06-21’ are longer than those on the cultivar ‘White Gold’.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying illustrations show characteristics of the new cultivar in photographs as true to color as is reasonably possible to make in illustrations of this nature. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Baptisia.
