Over the last ten years this Mediterranean plant has become very popular in Finland as an ingredient in salads to give them a litle extra kick. This of course means that the species is nowadays cultivated in Finland in gardens and professionally in fields. Some of it also manages to escape to the surrounding environment. Escaped rocket has a stronger flavour than the cultivated variety. According to the source of the information, rocket is either two species (E. vesicaria and E. sativa), two subspecies (E. vesicaria ssp. vesicaria and E. vesicaria ssp. sativa), or just one species, with the two different scientific names being synonyms for the same plant.

Common Dogmustard (Hairy Rocket)

Erucastrun gallicum

Another member of the Mustard family that is a close relative of rocket is common dogmustard, which is quite rare in Finland. Common dogmustard is more sparsely branched, has smaller flowers, is hairy, and its siliquae are longer and thinner than rocket’s.

Shortpod Mustard (Buchanweed, Hoary Mustard, Mediterranean Mustard)

Erucastrun incana (synonym Hirschfeldia incana)

NOT TRANSLATED YET. Meillä Suomessa harvinaisena tavattavan harmaakaalisinapin virallinen lajinimi oli aikaisemmin hilmiö. Kuten lähisukulaisensa sinappikaali, harmaakaalisinappi on yksivuotinen. Lidut ovat 8–15 mm pitkiä, varren myötäisiä, kapeita, lituperä noin 3 mm ja lidun nokka kypsänä pullea. Lehtien päätöliuska huomattavasti suurempi kuin sukulaisillaan.
