A Garden Book for Houston, 5th Ed. (2013) Such a marvellous resource for Houston gardeners. The book is in its 5th edition, published by the very fancy River Oaks Garden Club. This is a tome. Prepare to take a lot of time poring over the information. There is so much to learn from here. Truly, a book of Biblical proportions!
Someone to know when gardening in Houston. His seminal book on Houston gardening is available through Urban Harvest. Hope to meet him someday.
Earth-Kind (R) Landscaping
Information about beneficial, hardy, beautiful plants via Texas A&M's Agri-Life Extension services.
A fantastic educational resource for Houston gardeners, offering classes, books to borrow or buy, and discounts at certain gardening establishments.
Another Place in Time (Houston Heights)
Their tagline reads: "Your uncommon garden center." Certainly, it's that! Small, well stocked, with a great, varied, and changing selection of plants, including ferns and succulents. Folks there are really friendly to talk to and ask questions of, and they will leave you to be and enjoy the place unless you approach them for help.
Buchanan's Native Plants (Houston Heights)
Truly, a Houston institution, and aren't we lucky to live in a city with such fine local stores as these? Folks there are marvellously friendly and knowledgeable. Their offerings change day to day, so it's well worth visiting often (and budgeting before you visit).
Cornelius/Calloway Nursery (Woodlake/Briar Meadow)
Another store you want to enter with limited cash on hand. Unless you happen to be stinking rich.
The Ground Up (Spring Valley)
For vegan compost, mulch, stones, and more.
J.R.N's Nursery II (Alief)
We haven't been to "I" yet but "II" is pretty awesome. Their website doesn't let on much about what they have - this is a place to go to visit and have an adventure discovering. They specialise in fruit trees, but also carry lots of pots and decorative items, and a host of indoor/outdoor potted plants of all sizes.
Joshua's Native Plants (Houston Heights)
This was the very first local plant place we visited after moving to Houston. What a treat for the senses! And, Joshua is so much help. Friendly folk.
Nature's Way (Multiple locations - SW Houston)
Conveniently located in SW Houston (Missouri City), a source for different sorts of compost.
