Besides Exploring Creation through Botany as a main source, other complemetary living books would be those by Margaret Morley; “Seed Babies” , then “Little Wanderers” . We’re in Seed Babies, now; it’s delightful!
Also, reading through “Parables from Nature”, too. Wonderful stories and characters.
Lastly, “Plant life in Field and Garden” by Anabella Buckley (part of a series) for your older ones. All of these here: http://www.yesterdaysclassics.com/catalog/displaycatalog.php?catalog=nature
Although I haven’t gotten it yet (it will be in the next month or so), “Outdoor Secrets” seems to delight many here from SCm. It encompasses more than just plants.
Also, don’t forget your Creation Journals and Field Guides for WildFlowers and such things.
HTH,
