Artichokes

Overview

​For gardeners who have plenty of room, or for those who are looking for something unique and conversation-worthy, I highly recommend growing artichokes in Texas.  The globe artichoke is actually a type of thistle that is grown for its flower bud before bloom.  The base of the bud (the heart), as well as the bases of the inner and outer bracts are edible and delicious. 
Artichokes are perennial, but there are great varieties that can be grown more like annuals or biennials.  Growing artichokes in Texas takes lots of space and time, but the plants are an attractive addition to the landscape. The greatest part is that if you don’t get around to harvesting them, the flowers are gigantic and stunning.

​For the best results I highly recommend starting artichokes in 4” pots at the beginning of September, and transplanting them into the garden in the middle of November.  The plant will grow slowly over winter and should survive temperatures as low as 25 degrees.  If the temperature drops below that you can cover the plant with hay or a frost blanket to protect it.   As temperatures rise in the spring, the artichoke plant will begin to put on very large stalks and leaves, until finally it will send up flower buds in May and June. 

Site Selection

Artichokes are heavy feeders and require a lot of irrigation to perform best, although they don't like to have waterlogged roots.  A site with great drainage and lots of organic matter is ideal.  They do best with full sun, but can benefit with afternoon shade in the hottest part of the summer. 

Variety Selection

I have grown these two varieties with success in Texas.  Overall I prefer the purple artichokes as they seem to be more hardy and quite tasty.  Both varieties should work for you if you give them enough care. 
  • Green Globe - 175 days
  • Purple of Romagna - 240 days

You can buy a package of both of these varieties mixed in one at Botanical Interests.
