How about adding something completely different to your landscape? When C. Colston Burrell spoke in Tulsa he showed us slides of his gardens, including a palm - zone 7.
So, which palms should you grow in your atrium and which ones outdoors?
Timber Press has added a new book about palms to their Pocket Guide line. Click on the link to see their description.
Many palms can take cold temperatures as low as 5-degrees F, but not for many nights in a row.
Here in northeast Oklahoma many people grow hardy banana palms in their yards with a thick mulch in the winter. I dug mine up and put it indoors for the winter to see if it would grow bigger this year.
But I digress, back to the book.
On two of the early pages Riffle identified drought tolerant, water-loving, fast growing, ground cover and other categories of palms for easy reference.
Then, the next 200-pages are a ready reference for 200-palms with photos, descriptions, native habitat, and growing needs.
