Isoplexis canariensis

Originally from the Canary Islands, and Isoplexis canariensis is the best known of the species which are related to the foxgloves, although they do require different care and growing conditions. The wonderful flowers create a 'tropical feel' well worth the effort.

These are a tall growing plant reaching from just over 1m to 2m depending on conditions, wonderful orange flowers on tall spikes and attractive deep green foliage.

Isoplexis canariensis flowers are long lasting which is always an advantage. Birds and bees love them.
