New Buddleja globosa

I though I’d share a photo of my new Buddleja globosa cultivar, just flowering now for the first time. The flowers are primrose-yellow rather than the more common orange. It’s a descendant of HCM98017, a wild-collected B. globosa with very pale greenish-yellow flowers.

 

Mine, planted last June, is also starting to flower for the first time.

That is a nice looking plant, I like the colour.
How long did it take from seed to flowering?

 

I can get them to flower at a year old, but this stresses the plants and they’ve sometimes died straight after flowering. Generally, I allow two years from sowing to flowering. The females are shier to bloom, and I’ve had to wait three years for some.

The really time-consuming part is going from a seedling to being absolutely sure the cultivar is healthy and vigorous. There’s no point breeding from a plant until you know it’s a good ‘un. This yellow-flowered plant is line-bred, so it was essential the seed parent had no weaknesses that would be reinforced by the back-cross to the pollen parent.

 

Mine was not grown from seed but planted as a shrub.

 

That's interesting and useful.

 

I grew one of the orange ones when I still lived at home with my parents - but that was over 50 years ago! I'd never thought of growing one from seed but there are 100s of the other ones growing all over the place here! They often grow in a crack between a house wall & the pavement! In fact, till it was removed a couple of years ago, I got some photos of one that was growing in a wall of the underpass close to our flat!

I was going to upload one of the photos I took of it flowering but it's not on this computer, it must still be on the old one that I stopped using in January when I got this one.

I planted out a yellow Globosa a month ago. At the moment it's about 18 inches in height and I've grown it from a cutting.
