Today I thought I would share with you one of my all-time favourite plants, Bouvardia longiflora humboldtii.
There are many reasons why not only I but many gardeners love this plant in particular. Bouvardia.L. humboldtii is a very attractive plant; it has beautiful lush green leaves that are a great contrast against most other plants. The pure white flowers form in clusters all over the shrub, forming summer – autumn. The main attraction for most people and the main reason why these plants are so popular is the fragrance that is produced when these shrubs are in flower. Most of the Bouvardia genus originates from North America and South America and are a part of the Rubiaceae family. However, this species of Bouvardia in particular is native to Mexico. Bouvardia .L. humboldtii is a small growing shrub that grows to a maximum height of 1.5 meters and 1 meter wide.
Bouvardia humboldtii can be planted in full sun to semi-shade but requires a sheltered position from strong winds. It can also tolerate small frosts but may get tip burn on the foliage if it’s still young. Once these plants are established they are fairly hardy and resistant against frosts. Make sure to prune your Bouvardia humboldtii at the start of spring to encourage compact healthy growth otherwise prune once they have finished flowering. Feed with a complete ‘all-purpose fertilizer’ such as ‘Uplift’ from Yates in spring when new growth will start to emerge, and feed them once more when the flower buds appear in late spring. Well drained soil is best suited for Bouvardia humboldtii. If you have clay soil, mix some organic compost into the soil as this will help with water retention and loosen up the soil, making it easier for the plant’s roots to grow.
