Primulina 'Wu Gang' -- Is this the Breakthrough for Flowers from Seed?

Primulina 'Chasity' - Propagated by leaf



 Primulina ‘Wu Gang’  ---   Is this the breakthrough for flowers from seed?

 

            Primulina has a problem.  It takes a young plant too long to flower.  We sell Primulina as small foliage plants with a ‘hope and a promise’ that it will flower when it’s older.

 

            Here is the description of Primulina ‘Wu Gang’ (P. gueilinensis selection) in the Gesneriads journal, Vol 70, # 4, 2020.  You will find the picture on page 32.

Primulina ‘Wu Gang’, 2020, IR201531, (P. gueilinensis chance seedling selection), Wen Fang, Wei Yi-gang, and Li Shu of the Guangxi Institute of Botany, CAS & GCCC, Guilin, China. Cross made in Apr. 2018, seeds planted Jul. 3, 2018, first flowering Apr. 6, 2019. Fertile, true from seeds. Basal rosette, stem 1 cm long. Leaves green with white veins, 8-10 cm long × 5-7 cm wide, linear, with cuneate base, acute tip, and entire margin, hairy, petiole 2 cm long. Calyx split, green, 1 cm Fourth Quarter 2020 Return to Table of Contents 33 long. Pedicel 0.8-1 cm long, 5-10 flowers per axil. Corolla salverform, 6 cm long × 5-6 cm wide, purple. This cultivar is the choice selection from wild stock with larger flowers and linear leaves. It was determined that this variation is stable and these desirable features are passed through seeds. Shade tolerant but enjoys bright scattered light; prefers moist but well-drained substrate; will not bear temperatures below freezing.

 

So, where is the news?

 

It flowers in 10 months and will get 5-10 purple flowers per axil.

 

            Maybe this could be the flowering Primulina we need.  A lot of 2” wide purple flowers could make this Primulina worth growing.

 

            Commercial crops need to be fast, as in 3 months.  A 10-month crop would not be considered.  But if in 7 of those months, the seedlings didn’t take much space and if there is a big show at the end, it has a chance.

 

            We don’t know how many seed per seed pod, but it is a fertile selected species.

 

            Who has this seed?
