Santolina Pinnata Sulphurea, also known as ‘Cotton Lavender’, is a compact, rounded shrub that is ideal for a border or gravel garden as it typically grows to a height and spread of 1 metre.

One of the most striking features of this Santolina is its foliage, which is a grey-green colour and has a finely divided texture, they are linear and have a feathery appearance, giving the plant a delicate and elegant look. In the Summer, the plant produces small, yellow button-like flowers that are held above the foliage on thin stems which are highly fragrant and often used in potpourri and other fragrant preparations.

This is a highly adaptable plant that is tolerant of a wide range of growing conditions but it prefers a location that receives full sun and has well-drained soil, although it can also tolerate poor soil and dry conditions.

It is commonly used in gardens as a low hedge or border plant, where its unique foliage colour and texture can add interest and variety to the landscape. It is also highly attractive to bees and other pollinators, making it a valuable addition to any garden that supports wildlife.

Overall, this is a highly desirable plant that combines visual appeal with a range of practical uses, making it a great choice for gardeners of all levels of experience. With proper care and attention, this shrub can provide years of beauty and enjoyment in any landscape.

How to care for your Santolina Sulphurea

  • Planting: Choose a location that receives full sun and has well-drained soil. Dig a hole twice as wide and as deep as the root ball of the plant, and add compost or other organic matter to the soil to improve its nutrient content. Plant the shrub at the same depth as it was growing in its container, and water thoroughly after planting.
  • Watering: It is drought-tolerant and does not require frequent watering. Water deeply once a week during the plant’s first year of growth, and thereafter only during extended periods of drought.
  • Fertilising: Does not require fertilisation, but can benefit from an annual application of a balanced, slow-release fertiliser in the Spring to promote healthy growth.
  • Pruning: Prune in late Winter or early Spring to maintain its shape and encourage healthy growth. Remove any dead or damaged wood, and trim back any old or weak growth. If you are using as a hedge, prune it regularly to maintain the desired shape.
  • Mulching: Apply a layer of organic mulch around the base of the plant to help retain moisture and suppress weed growth.

By following these basic care guidelines, you can keep your Santolina Sulphurea healthy and looking beautiful year-round. With proper care and attention, this unique and visually striking shrub can provide years of enjoyment in your garden.
