Iris Ceasers Brother (Siberian Iris)

“Caesars Brother” is a variety of Siberian Iris that produces spectacular flowers. The showy, dark blue blooms are borne atop sturdy stems in spring and are great for attracting butterflies and other insects. The leaves are arching, narrow, blue-green, and grass like in appearance. This perennial typically grows to 40 cm tall and the same wide with the flowers standing up to 65 cm tall. It performs best when positioned in full sun on a well-drained site and is tolerant of short periods of dry, frost, and cool climates. It will generally die back during these times to regrow when conditions start to warm. “Caesars Brother” is commonly included in cottage gardens, planted around outdoor living areas, used in border plantings, or planted around the base of deciduous trees and shrubs. A mass planting is a must with this variety to give impact.

What is Siberian Catmint?

Siberian catmint is a popular common name often associated with a few different species and hybrids in the Nepeta genus, best known for their aromatic leaves and dainty, tubular flowers beloved by pollinators. While the true Nepeta sibirica is occasionally grown, most gardeners are seeking robust varieties such as Nepeta mussinii (Catmint) or Nepeta faassenii, which thrive in New Zealand conditions. These varieties tend to form compact, spreading tufts of grey-green foliage topped with abundant lavender-blue flower spikes.

How to Grow Siberian Catmint in New Zealand

Siberian catmint is perfectly suited to New Zealand’s diverse climate. It flourishes in full sun and well-drained soil—making it ideal for both coastal and inland gardens. After planting, water regularly until established; these plants are impressively drought tolerant once their roots take hold. Prune back after the first flush of flowers to encourage a second bloom later in the season. Even in a small garden, siberian catmint finds its place along paths, at the front of beds, or spilling over walls for that classic, relaxed look.

Why Choose Siberian Catmint?

Siberian catmint isn’t just about good looks. Its aromatic foliage helps repel pests like aphids, making it a smart companion for roses, vegetables, and other susceptible plants. Bees and butterflies love its flowers, while cats find the scent irresistible—though siberian catmint is generally tougher than its relative, catnip. For gardeners wanting to expand their Nepeta collection, consider exploring further options: Nepeta 'Walkers Low' (Catmint) offers an informal, sprawling habit with long-lasting blooms, while Nepeta 'Six Hills Giant' (Catmint) is perfect for a bolder statement in spacious borders.

Best Varieties and Companions

Among the standout siberian catmint choices for New Zealand, Nepeta mussinii (Catmint), Nepeta 'Blue Wonder' (Catmint), and Nepeta faassenii each offer subtle differences in size, hue, and flowering period. Try pairing siberian catmint with roses, lavender, or ornamental grasses for a vibrant, wildlife-friendly palette that lasts for months.
