Hosta ‘Branching Out’ – a breeding breakthrough

Hosta Branching Out PDN04-098 flowers3(64708)ccOne of the most rewarding parts of our work is being able to introduce a plant we’ve taken from idea (branched flower scapes) to reality. We are finally able to share our latest creation this week with the introduction of Hosta ‘Branching Out’. The first cross in the long road from creation to market took place here in 1989.  A seedling was selected that was later crossed with another 1995 seedling, which was later crossed with a 1999 seedling, which in 2004 was crossed with the blue-leaved Hosta ‘Pewterware’, after we noticed that both hostas would occasionally produce a single-branched flower scape.  We evaluated the resulting 2004 seedlings for several years before paring down their numbers in the semi-final cut. We were looking for good branching, attractive flowers, and sturdy stems. Once the final selection was made, we watched it for four more years to make sure it consistently branched in the garden, during which time, we also sent it north to evaluate its performance in colder climates.  Not wanting to significantly disturb the main clump, we removed a single division in 2012, which was divided annually.  Finally, in 2016, we are pleased to release our new baby to gardeners around the world.  We hope you find this as exciting in your garden as we do in ours.

 

Hosta parentage

Thanks for the great feedback on the hosta image.  Since most folks don’t have experience in plant breeding, we thought it might be interesting to share the crosses and parents involved to get to this point.  Our Hosta is PDN#10-004 and is a cross of PDN07-0793  x ((PDN05-156 x PDN04-180) (kikutii x ‘Gemstone’ (venusta ‘Minima’ x ‘Dorset Blue’) (longipes ‘Tardiflora’ x sieboldiana) x (venusta ‘Minima’ x self)) x PDN07-0100 ((‘Faith’ (‘Evening Magic’ (montana gold x sieboldiana) x ‘Big Daddy’ (‘Fortunei Robusta’) x PDN04-182) (kikutii x ‘Gemstone’) venusta ‘Minima’ x ‘Dorset Blue’ (longipes ‘Tardiflora x sieboldiana) x ‘Blue Mouse Ears’ (Blue Cadet sport))  So, the species included in creating this are Hosta venusta, sieboldiana, kikutii, longipes, and montana.
