A fine-textured, needle-like perennial that produces chartreuse flowers and foliage in spring, turning reddish in autumn. Extremely drought-tolerant once established and suitable for rock gardens or dry borders.

Why grow it

Cypress spurge offers fine texture and early season color interest uncommon among drought-tolerant perennials, with needle-like foliage and chartreuse flowers that shift to reddish tones. Once established, it requires minimal supplemental water and performs well in poor soils where many ornamentals struggle, making it suitable for low-maintenance xeric gardens or rocky sites. It presents a useful alternative to coarser sedums or junipers for gardeners seeking a more delicate visual character in dry settings.

Watch out for

This plant self-seeds readily in favorable conditions and may require deadheading or periodic removal to prevent unwanted spread within the garden. In regions outside its prohibited range, monitor for seedling establishment in adjacent areas if naturalistic conditions are present.
