Hola Rose
Parsnip seeds are best sourced in England or other Northern Europe countries or over the internet at sites such as tozersseds.com, thompson & morgan, as the plant is more readily grown in cooler climates.
Here in Spain, you can try sowing the seeds directly in well prepared ground at the first rains of autumn to harvest in the spring. Before sowing the seeds, soak them for 24 hours to speed up their germination.
Hope that helps and good luck, it is not something I have grown yet as my husband does not like most root vegetables.
We do have lots of fruits growing though:
Strawberries
Raspberries
Blackberries
Tomatoes
We also have Peppers and Garlic - we will be planting more soon such as lettuces and melons
