Calamondin or sweet orange
Updated: October 2026
The photo on the listing looks like a shop orange, small and bright, and you want juice. What you are about to order is often a calamondin, a sour hybrid that lives in a 12 cm pot, not a Valencia and not a Navelina. The difference is the fruit in the kitchen and the room you need in January. This page is that choice. It does not rank every pot in the [orange tree comparison](/hub/trees-and-palms/orange-tree), and it does not tell you how to deal with scale. Prices below are the amazon.co.uk figures from 19 October 2026.

Three oranges that are not the same fruit
A calamondin, Citrus × microcarpa, is the plant most mini orange titles are reaching for when they name anything. The RHS describes fruit about 3–4 cm across, a sweet peel and a very sour pulp, grown as a conservatory plant. That is a cooking orange, not a breakfast orange. A sweet orange, Citrus sinensis, including Navelina, is H2: it will not survive being frozen, and it is not what a 12 cm calamondin becomes if you feed it better.
What you can do with the fruit
You can eat a calamondin. The Carbeth bullets say the small oranges are edible and tangy, for marmalade, chutney, cocktails or a garnish. Plants4Presents reviewers, on an unnamed dwarf rather than a labelled calamondin, often call the taste sour. You will not juice a calamondin like a Valencia. A sweet orange is the one you eat fresh, and this Amazon set does not sell it. The checklist before you pay is the orange tree buying guide.
What this comparison is actually selling
Two Carbeth listings are named calamondins. The plain one is about £27.99, 4.7 from six reviews, in a 12 cm pot with an expected height around 30 cm. Plants4Presents, at about £24.79 with 4.3 from 95 reviews, is a dwarf orange with the species left blank. You have not bought a labelled sweet orange. The best orange tree page can still point you at a calamondin for a sill. It cannot point you at a sweet orange that is not here.
The winter that comes with the name
The RHS citrus guide puts calamondin at a night minimum of at least 13°C, in the light, with less water than in summer. That is a cool bright room or a conservatory, not a radiator shelf and not the open garden. Sweet orange is the more demanding winter. Love the Garden's copy on Citrus sinensis says damage is possible below about 7°C, next to the RHS H2 line: the plant will not survive being frozen. Once you have chosen the sour plant on purpose, the feed change and the leaf-drop checks are on how to grow an orange tree.
Common questions
Is a calamondin a real orange?
It is a real citrus, and it is not a sweet orange. The RHS lists it as Citrus × microcarpa, with small fruit, a sweet peel and very sour pulp. BBC Gardeners' World describes a mandarin–kumquat hybrid you use more like a lemon or a lime. The skin looks like an orange. The juice does not taste like a shop orange. Buy it for that sour fruit, or buy a different plant.
Can I eat the fruit?
Yes, with the taste made clear. Carbeth's listing calls the fruit edible and tangy, for marmalade, chutney, cocktails or a garnish. The RHS says the peel is the sweet part and the pulp is very sour. Bitter Seville pulp is a different case: Kew says it is not for eating raw. Do not eat the plastic fruit on an artificial tree at all.
Will it juice like a Valencia?
No. A calamondin fruit is about 3–4 cm on the RHS record, and the pulp is sour. You will not fill a glass the way you would with a sweet orange, and the flavour will not match carton juice. Use it as a garnish or in a marmalade if you want the fruit to earn its place. A sweet orange is the juicing plant, and it is not in this set.
What is a Seville orange for?
Marmalade. The RHS describes thick skin and sour, bitter fruit, grown in a container in a conservatory or greenhouse even though the record carries H3. Kew says the pulp of bitter orange is not for eating raw, and points at marmalade and liqueurs. A Seville is not a calamondin, and neither of them is a sweet eating orange. This Amazon set does not label a Seville either.
Can I grow a sweet orange in a flat?
Only if the flat can act like a cool greenhouse in winter, which most cannot. The RHS puts sweet oranges, including Navelina, at H2, meaning they will not survive being frozen, and recommends a cool or temperate greenhouse or conservatory, outside in summer. Love the Garden's copy suggests damage below about 7°C. A single radiator-side window is a poor match. A calamondin at 13°C on a bright sill is the more realistic mini tree, and it will still be sour.
Why do Amazon reviews say the oranges taste awful?
Because the pulp is supposed to be sour, or because the listing never promised a sweet orange. Plants4Presents reviewers often call the dwarf's fruit sour, and that page does not name the species. A calamondin that tastes sharp is matching the RHS description, not failing a juice test. If the review expected a clementine, the mismatch started at the title.
Do I need two trees to get fruit?
No. Suttons describes calamondin as self-fertile, and the RHS does not tell you to keep a second tree for pollination. Gardens4you is two plants because it is a lemon and an orange, not because an orange needs a partner. One named calamondin is enough. Fruit on a young 12 cm plant is a bonus, not a crop you should budget for. The RHS ultimate size of about 2.5–4 m is a grown plant, not the 30 cm parcel.
