Buddleja glomerata is a shrub endemic to the mountains of the Karoo desert in South Africa and is relatively hardy (-7°C to -10 °C), so can be grown in our gardens in Europe as long as it’s planted in a warm spot, for instance against a wall, and in rocky soil that is perfectly well-drained in winter.
Its main decorative attraction is the intensely silver colouring of the foliage which we like to associate with light pink flowering roses, the indented foliage of Artemisia arborescens, the steel blue of the Perovskia, the purples of Sedum, or the shimmering flowers of Salvia microphylla.
Cultivation and care:
Grow Buddleja glomerata in the sun in ordinary soil, which can be poor and dry. In its natural environment, this fast-growing shrub can grow up to four metres in height with a three metre spread!
In an ornamental garden it’s good to prune it drastically after flowering. Apply a thick mulch of rough compost at the beginning of winter.
