Care tips
It requires full sun for optimal flowering and well-drained soil, preferably sandy or sandy loam. Watering should be moderate once established, tolerating periods of drought, but benefiting from deep watering during hot summers. A common mistake is over-fertilization, which can promote leafy growth at the expense of flowering and weaken stems, making them prone to flopping. Prune in early spring to encourage dense growth and abundant flowering.
