Great masterwort is a unique and attractive perennial that is popular among gardeners for several reasons. Here are some of the special features of this plant:

The great masterwort (Astrantia major) is a herbaceous perennial plant that is native to Europe and western Asia. It is a member of the Apiaceae family, which also includes plants like carrots and parsley. The plant typically grows to a height of about 1 to 2 feet (30 to 60 centimeters) and produces clusters of small, star-shaped flowers that are surrounded by papery bracts (modified leaves).

The flowers can be white, pink or greenish-yellow, and bloom from late spring to early summer. The bracts are often more showy than the actual flowers and give the plant a distinctive appearance. It can be planted in garden beds or borders, and works well as a cut flower.

One of the defining characteristics of great masterwort is its foliage. The plant has deeply lobed, palmate leaves that are a rich green color and can grow up to 12 inches (30 centimeters) wide. The leaves are somewhat hairy and have a slightly rough texture.

In terms of care, great masterwort prefers to grow in partial shade or full sun in well-drained soil. It is fairly drought-tolerant but will benefit from regular watering during dry spells. The plant does not typically require fertilizer, but a light feeding in the spring can help promote healthy growth.

Overall, great masterwort is a fairly low-maintenance plant that can thrive in a range of growing conditions, and can provide color and interest to a garden for many years.
