It is not a climber, but here using a diamond-grid fence upon which to grow, just like the Ivy either side of it. Has pendant flowers in racemes (rather than panicles). |

Leaves vary in size from 3 to 10cm and are either hairless or sparsely hairy, the smaller ones are oval to cardioid in shape. |

Blossoms everywhere in dangling racemes. |
23rd April, Dunham Massey Park, Dunham Town. | Photo: © RWD |
The larger leaves with 3 to 5 lobes. All are irregularly but bluntly toothed. Racemes with spaced out flowers with 3-10 flowers/berries on a raceme 4-8cm long. |

Older stems glossy brown (right). Flowers shallowly bowl-shaped with 5 rolled over creamy-green sepals. These are NOT the petals, which are far shorter and within the bowl. |

The leaves. Differing varieties may have slightly differing leaves. |

The flowers always droop on Red Current (never upright). Leaves slightly bullate (raised 'blisters' on the surface between the veins). |

Flowers on short petioles (stalks) emerging from a short triangular bract. The sepal-tube is bulbous, hairless and shiny-green. It splits into 5 rolled-over creamy-green sepals. |

With a small green bract just before the flower petiole (flower 'stalk'). Berries closest to the main stem develop first (here not ripe; still green and still expanding). |

The flowers at the tips of the flowering raceme are the last to open. Petals here reddish probably due to either lack of rain or too much sunshine (or both). The style is green, in the centre, and forks into two stigmas at the tip. |

Fruits larger, but still not ripe (red). |

Bract from which the flower stalk (with short hairs) emerges and in a short distance joins onto the hairless shiny-green sepal tube which splits into 5 creamy sepals. |

The sepal tube merges into 5 sepals which widen and roll over. In-between the sepals are 5 short very narrow petals on the other side, you can just see some of them from the rear of the flower. |

From the top of the flower the 5 very short, narrow, creamy-green coloured petals can be seen between the much longer and wider sepals. 5 dumbbell cream-coloured anthers emerge between the petals. There are 2 pale-green styles in the central crater. The flowers are 4-6mm across and look like the negative terminal of a PP9 battery. |

This specimen has abnormally but 4 sepals but it does have the usual complement of 5 petals, 5 anthers and 2 styles. |

The petals have 2 lobes at the termination of their minuscule length. 5 Dumbbell cream-coloured anthers and 2 green styles in close-up. Unlike Mountain Currentwhich is dioecious the flowers of Red Current are bisexual. |

The domed blisters of the aphid gall Cryptomyzus ribis are at first yellow (extreme right hand side) before turning red as they mature early in the summer. The blisters seem to be bounded by the leaf veins, both major and minor veins, at least initially. |

The blisters grow much taller taking the minor veins with them (look at their shadows on the leaf surface). This aphid, Cryptomyzus ribis, occurs mainly on both Red Current and White Currants, but is not averse to occasionally attacking Black Current. |

The short stubbly hairs on the green parts of the leaf seem to get slightly longer and more numerous on the galled portions. The aphids, which are small, numerous, and yellowish-green, cluster in the hairy depressions on the underside of the leaf. But although they are born on Currants, when mature they leave the galls and instead fly to Hedge Woundwort plants (they can possibly detect the abhorrent odour of these plants, which contrarily some other humans find not unpleasant). There the aphids produce several more generations before returning to the Currant plants in the Autumn to lay their eggs on the twigs of the Currants. [It is left unexplained how they create these galls on the current leaves soon after the leaves open in spring]. |
It is directly related to other currants such as Black Currant, Mountain Current, Flowering Currant, and Gooseberry [which are all gathered together in the Currant (Grossulariaceae) family. Uniquely identifiable characteristics Distinguishing Feature : The shape and colour of the flowers, see photos.
No relation to : The flower does possess petals, but they are much shorter than the shallow-bowl shaped sepals and therefore not so obvious at all. It grows in woods, hedges, scrub and escapes from gardens up to 2m high but usually just 1-1.5m. It is thought to be native. The berry, which is edible, is 6-10mm across and usually bright shiny translucent-red when ripe (only rarely is it white). It grows throughout the British Isles although is rare in a great many places.
Several differing species of Currant were once widely cultivated across Europe and the cooler northerly parts of America. Occasionally the berry of the Red Currant is white and is marketed as 'White Currant', a botanical variety of Red Current (not a differing species). White berries are sweeter than the Red berries. The red berries of Red Currant are slightly more tart than the berries of
The juice of the berries contains 25 astringent compounds with very long chemical names, such as two carboxymethyl-indole glucopyranosides, several HydroxyBenzoyloxyMethyl-GlucoPyranosyloxy ButeneNitriles, and two GlucoPyranosylPhenylHex(e/a)nones - one called
