Gardeners' Notes:


On Aug 2, 2016, coriaceous from ROSLINDALE, MA wrote:

This is a hybrid of Buddleia fallowiana x Buddleia davidii.

Buddleias aren't long-lived (usually under 10 years). Hard pruning (to 6") annually in early spring helps it renew itself and improves bloom.

All B. davdii cultivars and hybrids require weekly deadheading for them to look and bloom its best.

Butterfly bushes may be good nectar sources for adult butterflies, but they are not food sources for the caterpillars of any Lepidoptera native to the continental US.

In some places, B. davidii can be an invasive weed: England, France, New Zealand, and the states of Oregon and Washington. It has naturalized in eastern N. America but is not considered invasive there. Recent cultivars are usually selected for dramatically reduced fertil... read more

A beautiful and unique buddleia. The growth habit is stately and upright. The leaves are soft and beautifully proportioned. The whole plant, stems included, are very "silver" and contrast with rich green plants in the summer garden. The flowers are a very icy lavender color and the orange eyes just make them glow, especially in twilight. Very aromatic.

There seem to be a few photos in this plant listing that may not be 'Lochinch.' Marilynbeth's pics are very accurate.

More praise for this plant:

I had two davidii butterfly bushes in addition to my lochinch. The past 3 years the davidii became more and more diseased with curling powdery leaves and thin growth (I've noticed this on other butterfly bushes in my region). Eve... read more

Buddleia fallowiana 'Lochinch' BUTTERFLY BUSH Dec (z7) (Fra,Bfly,Hon)
The undersides of the wide, gray-grn leaves are covered with white, woolly hairs on this tender med-sized shrub, but that doesn't keep the butter-flies from enjoying the long clusters of fragrant lilac-blue fls.S/M

This is one of my favorites, seems to bloom longer then all the other Buddleja I grow, and the silvery foliage is a nice contrast.

This plant grew for 4 years in my yard, and I just loved it's rounded shape and silvery foliage. However, this past winter was wet and wild (back to normal) and the lochinch never appeared at all this year. I"ve replaced it with nanho blue, hopefully hardier.

I purchased a collection of 6 butterfly bushes from Springhill nurseries in early spring. Of the 6 tiny plants I received, only the Lochinch, and Potter's Purple seem to have thrived and bloomed, although all received similar locations and care. The rest - honeycomb, pink delight, harlequin and royal red appear stunted and I don't know if they will survive their first winter here. I am pleased with the two noted above, however.
