Buddleia davidii ‘Nanho Blue’

Buddleias are pretty tough plants and the only one I have ever lost was a dwarf one in the old garden after a very hard winter. This spring I was certain I had pruned mine back too early and a late frost appeared to have finished them off… a disaster for my Butterfly Bed where four different shrubs are the main focus of the bed.

I was wrong. By May they were all sending out shoots with new leaves appearing daily. Now they are back to the size they were last summer and the first flowers are opening. I am writing this down as a record to remind myself not to panic again next spring!

My favourite is Buddleia davidii ‘Nanho Blue’ (also called Buddleia davidii v. nanhoensis). This was featured in my vase last Monday (see here) and a few comments prompted me to take a second look at this shrub.

The reason I love it is partly for the fragrance of its flowers, which is not as overpowering as some. But the main reason is its foliage. The leaves are narrow – longer and thinner than other buddleias – and smoother too. As with my other buddleias they are also silvery. The combination of the smooth silver with the blue flowers is rather attractive, but even when it is not in flower it looks pretty. It retained most of its leaves throughout the winter as well, although they do look a bit worse for wear by the time I prune it in spring.

The flowers are also longer and thinner than other buddleia I have grown.

But what stood out in the photos of my vase the other day was the bubbly clusters of petals on each panicle.

This occurs on most of the flower heads it seems, and the effect is rather pretty. I think most of my buddleia have similar clusters, but because they are shorter and fatter flower heads it isn’t noticeable once they are in full bloom.

I planted a second Nanho Blue in the Oval Bed. This one is still quite compact….

 …… but the one in the Butterfly Bed is already about 2m tall and at least 1.5m wide. It isn’t supposed to get any bigger than that….

I will have to post some more photos once it is in full bloom… preferably with a few butterflies on it. 😉🦋

I think almost every garden has a buddleia, doesn’t it? So which buddleias have you grown and do you have a favourite? Are they invasive in your part of the world? Do they grow in warmer climates?

Thanks for reading and have a great gardening weekend!
