My name is Bob Walsh. I have been growing tropical plants in Chicago, USA, plant hardiness zone 5, for more than 20 years. The past 10-plus years I focused on developing successful growing techniques for plumerias both indoors and outdoors, which resulted in the publication of my step-by-step plumeria care book, How To Grow Plumeria - Frangipani Anytime Anywhere!, at Bob Walsh Plumeria Care.
