UK Grown, Herbaceous & Evergreen Perennials

Most perennials are grown for their flowers, some for their foliage, but they are all hard-working plants that fill your borders with colour and texture - most of them are happy in patio containers as well.

Strictly speaking, a perennial plant is anything that lives for more than two years, so trees and shrubs are all woody perennials. But in common garden usage, perennial usually refers to herbaceous (i.e. non-woody) plants, which produce new stems every Spring; these stems flower the same year and then die back to the ground in Winter, sometimes remaining in place for interest until you trim them off the following Spring. The cycle is repeated annually, and the plant has a life expectancy of never less than three years (and typically much longer), otherwise they are an annual or biennial flower (commonly called bedding). Evergreen perennials are also non-woody, but they are always in leaf, and only their flower stalks come and go each year.

Most of them are hardy, but some appreciate the protection of hay or mulch to insulate them in winter: the hardiest perennials are generally smaller alpine plants, which are best for rockeries. Perennials usually flower in spring and summer, some in early autumn, bringing colour and structure in summer, invariably attracting bees and butterflies in the process.

We grow tried and tested favourites, and new varieties. Our top quality, disease-free plants are grown in pots that are increasingly recyclable, and we use peat-free compost whenever possible. 

All our perennial plants are covered by our no-quibble Guarantee, which means you can order with complete confidence. Best advice & friendly support throughout.

Choosing Perennials

Our herbaceous perennial collections of eight plants give you a bit of a surprise and the best value. Agapanthus and heucheras are both bushy evergreens, the former is less hardy and has showier flowers, the latter is hardier with nicer leaves. Salvia is a flexible, tough plant that loves poor dry-ish soil and is superb for bringing in the bees and butterflies. Lupins are some of the world's funkiest looking flowers, the taller ones are good anywhere in the border, and the smaller ones are also excellent in patio pots.

Growing Perennials

For the most part, the joy of perennials is their relatively undemanding nature: give them a well drained soil and more than half a day of sun, and they will thrive with only a bit of tidying, some feeding and watering in the growing season, and hopefully almost no weeding because they cover the soil so well. 

As perennials mature past a few years, they tend to form clumps that bulge or spread. In many, but not all cases, you can dig these up, split them, and replant the pieces - remember to water them as if they are new plants in their first summer.
September-October is a great time to divide early flowering perennials, so they can put down some roots before winter, and Spring is also fine for late flowering plants, right as the new foliage shows signs of emerging - remember that if your soil is sticky clay, early Spring is always the best time for moving any perennials.
As long as you water them, you should get away with splitting them during the growing season if you have no choice, but it's best done while they're still dormant.

What does not divide well? Hellebores and Dieramas don't like it at all.
Plants with a deep taproot, like lupins, hollyhocks, acanthus, and most verbascums, poppies and eryngiums can't be divided easily, but they either spread by seed, or you can propagate them via root cuttings in late Autumn or early Spring.

It's a myth that splitting plants every year is beneficial for most plants. Helenium and Phlox are the most "demanding" - every two years tends to suit them best, and older heucheras and primulas might creep into that range as well to keep them fresh looking.
You can see for yourself when clumps are ripe to divide every few years, and if there is a bald patch in the middle, it's overdue a breakup! Roll Moody Blues.

Our RocketGro Compost Soil Improver is the stuff for any tired garden border, while perennials in pots often prefer the slightly richer Black Gold Compost
