A few weeks ago, my sister-in-law asked me to come and look at her garden. She needed some advice. The flowerbed at the front of her house was full of weeds, and she didn’t like the path to the front door, or the old stone wall. Time to start again!
Her main question was: what plants should I put in so as to have as little maintenance as possible? She and my brother are often outdoors in the summer, and they have very active children who have to be transported here and there. In short, they don’t have much time to maintain their garden. No problem!
My father, Larry Hodgson, has dedicated his career to making gardening as simple as possible, so that we can enjoy beautiful flowerbeds without sacrificing all our free time. There is such a thing as an almost maintenance-free garden. Let’s take a look at a few perennials that, according to him, are not only easy to maintain, but are hardy and will last for decades.
Bear’s Breeches

Uncommon in our gardens, this is a perennial with a long flowering period. Its cut foliage comes out early in spring and remains attractive until autumn.

Recommended species and cultivars: A. × cammarum ‘Eleanora’, A. × cammarum ‘Pink Sensation’, A. × cammarum ‘Eleanora’, A. carmichaelii ‘Arendsii’, A. napellus ssp. vulgare ‘Albidum’
An easy-to-grow, resilient perennial, wolfsbane can live up to 40 years.

Hardiness: depending on species, 3-5 (USDA 3 to 9)

One of the few plants with truly blue flowers. It remains attractive after flowering thanks to its pointed, willow-like leaves and sturdy stems. Its main attraction is its golden-yellow autumn color.
Wild Indigo
Baptisia
Size: depending on species, 25-200 cm (10-78″) high x 60-200 cm (24-78″) wide

With its violet-blue flowers, Wild indigo resembles lupine, a close relative. A large perennial, it acts as a shrub. Slow to establish, it is nevertheless almost permanent.

A classic in our gardens, but what a bloomer! This perennial forms small, heart-shaped flowers. Plant it where it won’t be seen, as it often goes dormant and its leaves turn yellow in summer.

Daylily flowers last only one day, hence the name “daylily”. There is usually more than one bud per stem. With flowering times ranging from three weeks to several months, depending on the species and cultivar, they have a reputation for being very easy to grow.
