Know before you buy
Unlike traditional cardoons that feature sharp, prickly thorns, the Porto variety is bred to be smooth. This makes harvesting and preparing the stalks significantly easier and safer, as you won't need heavy-duty gloves to handle the plant.
To blanch the stalks, gather the leaves together and wrap them with burlap, cardboard, or heavy paper about three to four weeks before harvest. This excludes light, which reduces bitterness and encourages the stalks to become pale and tender.
Yes, this variety is container-friendly. Because the plant grows quite large, ensure you use a deep, sturdy pot with excellent drainage and provide consistent moisture to support its growth.
Once blanched and harvested, the stalks have a distinct, savory artichoke flavor. They are best prepared by peeling away any tough outer strings, then boiling, braising, or frying them until tender.
It is both. With its tall, architectural growth habit and silver-green foliage, it makes a striking focal point in a flower border or landscape, even if you choose not to harvest the stalks.
These seeds require full sun and a warm soil temperature between 70-80ºF to germinate successfully. If you are starting them in cooler climates, consider using a heat mat to reach the optimal range.
