About Echinacea 'Tomato Soup'
Echinacea 'Tomato Soup' · also called Tomato Soup coneflower, red coneflower · flowering
Echinacea 'Tomato Soup' is a vivid hybrid coneflower with large, warm tomato-red to deep orange-red petals and a rich copper central cone. Plants reach 60–75 cm and bloom from midsummer into autumn. Drought-tolerant once established and highly attractive to bees and butterflies. Not listed as toxic by the ASPCA; safe for pet-friendly gardens.
Preferred mix: Well-drained loam or gritty loam
Watch for — Powdery mildew: Can develop in late summer, especially with dry roots and humid air. Improve spacing for airflow and water at the base.
Why echinacea 'tomato soup' needs this mix
Echinacea 'Tomato Soup' is a Mediterranean dry-hillside plant — it wants a lean, sharply drained, slightly alkaline mix, and rots fast in rich, water-holding soil.
- Echinacea 'Tomato Soup' evolved on stony, sun-baked slopes — its roots expect to dry out hard and quickly between rains, so the mix must drain almost as fast as you pour.
- A lean, low-nutrient mix keeps growth firm and aromatic; a rich one gives soft, sappy, flavourless growth that flops and rots.
- It tolerates and often prefers a slightly alkaline soil, the opposite of most houseplants.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons echinacea 'tomato soup' struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Rich, moisture-holding compost is the classic killer of echinacea 'tomato soup' — especially over a cold, wet winter, when the base of the plant simply rots.
- A peaty, acidic potting mix is doubly wrong: too wet and the wrong pH direction.
- No grit means the rootball stays damp for days, which a dry-climate root system never copes with.
Growing echinacea 'tomato soup' in ordinary rich, moisture-retentive compost. Lean it out with at least a third grit, and never let it sit wet over winter.
pH — does it matter for echinacea 'tomato soup'?
Echinacea 'Tomato Soup' likes neutral to slightly alkaline soil, roughly pH 6.5-7.5. If your soil or compost is acidic, a little garden lime or extra grit nudges it the right way — the one common plant where you may add lime.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
Bagged "herb" or "Mediterranean" mixes are usually fine for echinacea 'tomato soup', but most standard composts need cutting hard with grit. The DIY ratio above is cheap and exactly right.
Drainage and the pot
Sharp drainage is everything: a terracotta pot with a big hole, gritty mix and never a saucer left full. Raised beds suit these herbs outdoors for the same reason.
A gritty mix barely breaks down, so echinacea 'tomato soup' needs little repotting — refresh the top layer and the grit every couple of years rather than potting on aggressively. When the time comes, our repotting guide for echinacea 'tomato soup' covers the timing and technique step by step.
