Irises are highly popular flowers in many gardens and for good reason – they’re hardy, reliable, and beautiful. Many gardeners prefer them because, in addition to being graceful and colorful – after all, the word “iris” means “rainbow” in Greek -- they attract butterflies and hummingbirds.

Among the over 300 species of irises worldwide, Siberian Irises in particular are popular because they are among the easiest to grow in a temperate climate like ours, easily adapting to USDA Plant Hardiness Zones 3 to 8. While the name might sound like they prefer a colder climate, they are in fact a group of hybrid flowers developed from two blue-flowered Asian species. The Siberian Iris (Iris sibirica) sports amazingly long lasting flowers in a cool and consistent spring. Too much rain and heat will wilt flowers prematurely. The most common is ‘Caesar’s Brother’ (photo).

Every landscape – both natural or managed – is dynamic. Nothing is frozen in time. Without proper, ongoing care, all built landscapes and managed environments will experience a slow and steady degeneration until the only remedy is complete renovation. Even with care the maturing and aged landscape of 15 plus years can start to outpace the space.

What’s needed to avoid major landscape surgery is periodic, year-round assessment that enables you to see and gage your landscape’s performance and determine what needs focused, more proactive attention and what can coast along with minimal care. Take notes and photographs to refer back to later in the year. Use them to review progress at each new phase and season and to act as a baseline for change. Keep in mind, that you can only put off care and change for so long. If you see an issue, address it as soon as you can.
