These 2 photos of cardamine were taken by me on 18th December 2023 in Regional Fruit Research Centre, Vengurla, Sawantwadi.
This institute makes new varieties of Mango, Cashew and other fruits and cultivates them to sell it to farmers in the region.
And this above 2 photos were taken on 4th August 2023 from Somaiya Campus.
In both these regions soil is brought from other areas hence we can say that Migration of Cardamine happens through nursery or garden soil.
