Vitex agnus-castus Pink Pinnacle - Chaste Tree

Vitex agnus-castus 'Pink Pinnacle' is a new variety of Chaste Tree with reduced growth, perfectly suited to small spaces and container gardening. This shrub with a rounded habit has more than one advantage: summer flowering of fragrant light pink spikes, decorative and aromatic fruiting, beautiful palmate grey-green foliage that emits a scent, good cold resistance, and exemplary frugality and sobriety. The list of its qualities would be incomplete without mentioning that it tolerates coastal conditions and adapts to salty, sandy, poor, or even limestone soils. Objectively speaking, few plants can compete with this versatile Vitex, which is ready to make its entrance in any garden.

Vitex agnus-castus is a shrub from the Verbenaceae family, native to the Mediterranean basin and Asia Minor. While it is particularly robust and easy to grow, it is often criticised for its excessive growth and disorderly habit. These flaws are corrected with this new 'Pink Pinnacle' dwarf variety, recently obtained after years of experimental breeding in the United States, at the University of Georgia.

'Pink Pinnacle' has a very round and bushy, compact habit, with gracefully upright branches. When mature, it will reach approximately 1.5 m (5 ft) in all directions. Its flowering occurs from July to September, depending on the climate, on the current year's growth. Erect spikes, adorned with tiny light candy-pink flowers, cover the plant. Then small fruits the size of peppercorns appear, which are very aromatic, dark red and shiny, and persist until winter. The fast-growing stems are sturdy and very flexible. They develop palmate leaves, divided into 5 slender lobes, quite late in spring. The colour is a dark greenish-grey, matte and slightly silvery when they emerge. The foliage emits a strong pepper scent when crushed, hence its nickname of "Pepper Tree". Vitex plants have a very deep root system, allowing them to draw moisture from deep down when the summer is dry. In very cold regions, the above-ground parts of the shrub will be destroyed, without detrimental effects to the plant, which will regrow within a few months and flower abundantly on new shoots. The deciduous foliage falls in autumn.

Often found by the coast, sometimes very close to the shore and anchored in the sand between rocks, Vitex agnus-castus withstands drought once well established, much like the Tamarisks with which it gets along. Having retained the qualities of this undemanding and sturdy shrub, the 'Pink Pinnacle' variety proves to be more compact, brighter, and easier to use in the garden, even in limited spaces. Its moderate growth allows it to be planted in small perennial beds, in a container on the terrace, or at the front of a shrub border. For example, associate it with oleanders (in mild climates), dark pink repeat-flowering roses (‘Pink Knock Out’), dwarf buddleias, or even a summer-flowering tamarisk. This shrub, resembling a giant pink lupin, looks stunning surrounded by yellow daylilies, shrubby lavender, and grasses like Yaku jima Miscanthus, etc.

Its vernacular name, 'Monk's Pepper', dates back to the Middle Ages when some clergymen consumed the shrub's berries to resist carnal temptations. Since then, studies have proven the plant's properties in alleviating problems related to hormonal fluctuations in women. In Ancient Greece, Vitex stems were used to make strong bindings. Legend has it that Ulysses bound his companions with such ties, under the bellies of sheep, allowing them to escape from the Cyclops' cave.
