What is Heather World?
Heather World is an enthusiast-run reference site devoted entirely to heathers — the shrubs in the genera Andromeda, Calluna, Daboecia and Erica. It is aimed at people who have recently become interested in these plants as well as experienced growers, and it gathers cultivar lists, photographs, cultivation guidance and more scholarly material in one place, according to Heather World.
Its scope runs from the practical to the botanical. The site covers choosing, growing and propagating heathers, alongside scientific studies and nomenclature. It also looks beyond garden varieties to wild heathers of European heaths and moorlands and to the rarer South African or "Cape" heaths, with sections such as Heather Gardens and Erica in Summer reflecting that range.
A notable part of the site is its archive role. Heather World was home to the old Heather Society, a group of heather enthusiasts that closed at the end of 2020; its Yearbooks and Newsletters remain viewable there. For anyone researching older cultivar names or the history of heather growing, that back catalogue may be as useful as the growing advice.
Who it suits
- New growers wanting an overview of the four heather groups and how to choose and cultivate them.
- Collectors and specialists comparing cultivars, including unusual Cape heaths, through the lists and images.
- Researchers and historians consulting the archived Heather Society Yearbooks and Newsletters.
A sensible next step is to identify which genus your plant belongs to — Calluna, Erica, Daboecia or Andromeda — since their cultivation needs differ, then use the relevant cultivar list and growing notes rather than treating "heather" as a single category.
Which heather varieties are best for a small garden?
For a small garden, prioritise compact summer-flowering heathers and low-growing winter heathers rather than the tall tree heaths. The four groups covered on Heather World — Andromeda, Calluna, Daboecia and Erica — behave quite differently in a confined space, so the group matters more than the individual name.
Quick comparison
| Group | Typical garden role | Small-garden fit |
|---|---|---|
| Calluna (summer heather) | Flowering carpet in sun; huge cultivar choice | Excellent — many compact forms, good for edging and containers |
| Daboecia (Irish heath) | Loose, long-flowering shrub | Good, but give it room; best in a border or large pot |
| Erica (winter and summer heaths) | Winter colour, ground cover, alpine troughs | Excellent — the summer-flowering sorts are especially useful |
| Andromeda | Small, neat shrub for acid, damp ground | Good where soil is reliably moist and lime-free |
What to pick in practice
- For a low carpet of colour in full sun: a compact Calluna cultivar. These are the workhorses of a small heather bed and look right at the front of a border.
- For flowers over a long season: Daboecia, which keeps going through summer, though it is looser and less tidy than Calluna.
- For winter interest: a winter-flowering Erica, which gives colour when little else does.
- For a damp, shady corner: Andromeda, which suits wetter acid ground that would defeat the others.
The page's cultivar lists, with images of many forms, are the practical place to check habit and flower colour before choosing. Note that the old Heather Society closed at the end of 2020, but its Yearbooks and Newsletters remain on the site — useful if you want to see how particular cultivars performed in real gardens rather than just catalogue descriptions.
Decision criterion
If you can only plant one thing, choose a compact Calluna for sun and a winter Erica for year-round structure. If your soil is neutral or alkaline, or your space is a windy rooftop, check the cultivation guidance before buying — most heathers want acid, free-draining ground, and that constraint will narrow your list faster than size will.
A useful next step: measure your patch, note its sun and soil, then browse the cultivar lists for forms described as low or compact and match them to the season you most want colour.
How do I grow heathers in different soil types?
Match the heather group to your soil first, then adjust the soil to suit the plant rather than forcing one plant to cope with everything. Heather World organises its cultivar lists around the four main groups — Andromeda, Calluna, Daboecia and Erica — and covers choosing, growing and propagating heathers, which is the right order to work in.
The four groups and what they expect
- Calluna (Scotch heather): the classic moorland plant. It wants acid, free-draining ground and full sun. It will sulk in lime.
- Erica: the largest group, ranging from European heath and moorland species to the South African "Cape" heaths. Soil preferences vary widely between species, so check the individual species rather than treating "Erica" as one plant.
- Daboecia (St Daboec's heath): generally more tolerant and longer-flowering, but still happiest in acid to neutral soil that does not dry out completely.
- Andromeda (bog rosemary): a small group for damp, peaty, acid sites. Not a plant for dry borders.
Acid soil (the easy case)
If your soil is already acid and drains reasonably, most heathers will settle in with little fuss. Improve structure with well-rotted organic matter, plant so the base of the foliage sits at soil level, and mulch with an acid-friendly material such as pine bark or leafmould. Avoid mushroom compost and anything limy.
Neutral to alkaline soil
This is where most failures happen. Two workable approaches:
- Plant in a raised bed or mound of ericaceous compost mixed with grit and bark. Keep the mound generous — roots must never reach the surrounding lime.
- Grow in containers using ericaceous compost, which gives you full control and suits the smaller and more tender Erica species, including the Cape heaths that need protection in cold, wet winters.
Water with rainwater where you can; tap water in hard-water areas steadily raises the pH of a container.
Wet or heavy clay
No heather enjoys sitting in waterlogged clay, and Andromeda is the only group that welcomes genuinely damp conditions. On clay, plant on a slight mound, break up the subsoil beneath, and add grit. If drainage cannot be fixed, choose containers.
Dry, sandy or exposed sites
Calluna is the best bet here, along with the more drought-tolerant European Erica species. Add organic matter at planting to hold moisture through the first season, then mulch annually.
A quick comparison
| Soil type | Best starting point | Main risk |
|---|---|---|
| Acid, free-draining | Calluna, most Erica | Drying out in the first year |
| Neutral to alkaline | Raised bed or containers | Lime-induced yellowing and decline |
| Heavy clay | Mounded planting or pots | Waterlogging around the roots |
| Damp, peaty | Andromeda, moisture-loving Erica | Drying out in summer |
| Dry, sandy | Calluna, drought-tolerant Erica | Establishment failure without mulch |
A practical next step
Before buying, test your soil pH with a simple kit, then check the cultivar lists on Heather World for the species you are considering — its group listings and images let you match a plant to your conditions rather than guessing from a label. If your soil is alkaline, decide now whether you are prepared to build a raised bed; that decision matters more than any fertiliser you might add later.
What is the difference between Calluna, Erica, Daboecia, and Andromeda?
Calluna, Erica, Daboecia and Andromeda are the four groups of plants generally gathered under the name "heather." They look similar at a distance — wiry shrubs with small, often needle-like leaves — but they differ in where they come from, when they flower and how fussy they are in a garden. Heather World groups its cultivar lists and photographs under exactly these four names, and covers wild European heath and moorland species alongside the South African "Cape" heaths.
The practical differences
| Group | Typical garden role | Flowering season | Hardiness and soil |
|---|---|---|---|
| Calluna (Scotch heather) | The mainstay of heather beds and winter-interest planting | Late summer to autumn, with foliage colour carrying through winter | Fully hardy; needs acid, well-drained soil |
| Erica (heaths) | The longest season of interest, because different species bloom at different times | Some in winter and spring, others in summer and autumn; South African species flower in summer but are frost-tender | Mixed; most hardy species need acid soil, but some tolerate lime, and Cape species need frost-free conditions |
| Daboecia (St Dabeoc's heath) | A smaller, looser shrub for the front of a border | Long succession from early summer into autumn | Hardy in mild areas; acid soil, dislikes drying out |
| Andromeda | A curiosity rather than a bedding plant | Late spring to early summer | Needs consistently damp, acid, peaty ground |
The most useful distinction for a gardener is the flowering calendar. Calluna gives you the autumn-to-winter display. Erica is the group that spreads flowers across the whole year, which is why the site's own headings dwell on "Erica in Summer" — that group includes the summer-flowering species as well as the winter ones. Daboecia fills the gap in mid-season with a long, repeating flush. Andromeda, by contrast, is a bog plant with narrow, blue-green leaves; it is grown for interest and for wet, peaty sites rather than for mass colour.
A concrete way to choose
Walk your intended planting spot and note two things: the soil pH and how wet it stays. If the ground is acid, free-draining and you want colour from August through the winter, start with Calluna. If you want flowers in a specific month — say June or February — pick the Erica species that flowers then, checking hardiness if you are tempted by the Cape heaths. If you have a damp, peaty hollow that never dries out, Andromeda will settle where Calluna would sulk. Daboecia suits a sheltered, mild garden where its long flowering run is worth the extra care.
A sensible next step is to look at the cultivar lists on Heather World and read the entries by group rather than by name, so you can see which season and soil each one expects.
How can I propagate heathers from cuttings?
Propagate heathers from cuttings by taking short, non-flowering side shoots in late summer, rooting them in a gritty, acidic mix under cover, and keeping them humid but not wet. Expect the process to take a few months rather than a few weeks.
The key details that decide success:
- Timing. Late summer to early autumn is the usual window; the current season's growth has firmed up but is not yet woody.
- Cutting material. Choose healthy, non-flowering shoots from the outside of the plant. Flowering stems root poorly and waste the plant's energy.
- Length and base. Short cuttings of roughly 2–5 cm are typical, pulled off with a small heel of older tissue or cut just below a leaf node.
- Compost. A free-draining, lime-free mix suits heathers. Ericaceous or acidic compost with added grit or perlite is the practical choice.
- Conditions. High humidity and indirect light, usually under a polythene bag or in a closed propagator, with the cover removed briefly to ventilate.
- Aftercare. Once roots hold the compost together, pot the cuttings on individually and grow them on before planting out. Heathers resent disturbance, so handle roots gently.
A realistic reader scenario: you have a well-established Calluna or Erica in the garden and want more of the same named plant, because seed-raised heathers rarely come true. Taking twenty cuttings rather than five costs little and covers losses, since strike rates vary between species and cultivars.
Heather World is a useful reference point for this, because it lists cultivars across the four main groups — Andromeda, Calluna, Daboecia and Erica — alongside images, and covers choosing, growing and propagating heathers. That matters when you are selecting which plant to propagate: a summer-flowering Erica and a winter-flowering one need slightly different timing, and the site's separation of the groups helps you identify what you actually have before you start cutting.

Where can I find old Heather Society yearbooks and newsletters?
The old Heather Society's Yearbooks and Newsletters are available on Heather World, which hosts them alongside its wider heather reference material.
What you will find there
Heather World is a specialist reference site rather than a shop or forum. Its content covers the four main heather groups — Andromeda, Calluna, Daboecia and Erica — with cultivar lists and images, plus cultivation advice on choosing, growing and propagating heathers. It also spans wild European heath and moorland heathers and the South African "Cape" heaths, and touches on scientific studies and nomenclature. The Society itself closed at the end of 2020, so the site now acts as its archive.
How to use it
- Go to the site and look for the Heather Society section rather than the cultivar lists, which are organised by plant group.
- If you are searching for a named cultivar, use the group lists first; if you want historical articles, talks or cultivation write-ups, go to the Yearbooks and Newsletters.
- Expect scanned or archived documents rather than a searchable modern database, so browsing by year or issue is usually quicker than keyword searching.
Who it suits
Gardeners wanting practical cultivation guidance will get more from the cultivar lists and growing tips. Researchers, society former members and anyone tracing the history of heather growing in Britain will find the Yearbooks and Newsletters the main draw. If you need current supplier lists, prices or live society events, this is an archive rather than an active organisation, so treat it as a historical record.
