Did you know that perennials are the backbone and fundament of any garden? They are the most show-stoppingly beautiful and easy-going of all plant groups. Perennials are plants that will return year after year. Unlike annuals, which complete their life cycle in one growing season, perennials are typically hardy plants that will make a comeback after a few months of rest. They usually flower for one (long) season and will die back in winter, only to reappear the following year with a grand display of flowers. However, some perennials bloom in winter or flower multiple times during one season. Echinacea, Rudbeckia and Salvias are some examples of perennials. Do you want to know more about this fantastic plant group? Stop by Ahern Nurseries & Plant Centre to find the perennial matching your garden plans.

Want a garden that is visually attractive year-round?

Perennials give structure to the garden because, as mentioned, they return every year - some even for decades. Combining these perennials with annual plants provides a new experience every year. While bedding plants are the one-season wonders that add colour and need to be replaced every spring, perennials are the strong foundation of your garden. To make the most of your garden, you probably don't want a day without a splash of colour. If you make a nice little plant-plan, you'll have something in flower for every week of the year.  By carefully selecting the different bloom times, you can create a garden that grows and blooms all year round - even in the year's darkest months. We have various perennials in stock according to the season.

Why you should add some perennials to your garden

Many perennials have leaves that are visually appealing even when not in bloom. There is also a wide variety of flower colours and shapes to choose from in the world of perennials. One advantage of perennials is that they require minimal maintenance. They often only need well-draining soil supplemented with compost or organic matter. We supply perennials in pots that can be placed directly in the border or a container. Plant the right plant in the right place: there are perennials for every spot in your garden, whether shady, sunny, dry or damp. Ask our garden centre staff in Limerick for help if you're unsure which to choose.

Containers & planters


Some piece of advice: plant in threes or fives for the most significant impact: drifts or groups of the same plant catch your eye and demand to be noticed.

When to plant perennials

We often get questions about the most suitable time to plant. The answer is simple: you can grow a perennial at any time, but the best time is autumn or spring. This allows the plant to settle down well before winter or a very hot and dry summer is approaching. We prefer autumn because the soil has already warmed up and is relatively moist. You can also plant in the summer, but you must water regularly. In any case, avoid periods of frost.
