The Quinine tree or large shrub has provided medical cures for malaria and fever for 400 years. The ground up bark is the key substance for this and as the additive in tonic water.

A common site in many town gardens are trees that have outgrown their space. Large native trees like Oaks, Copper Beach, Planes, Weeping Willow and horse chestnuts are wonderful, but to be really enjoyed they need suitable space, like in a park. If they are planted in the garden they will

For over 25 years I have gardened a rockery or rock garden on a triangular patch of poor soil. I progressively scrounged and collected a range of granite, limestone and sandstone rocks and added them piecemeal. I aspired to growing alpine plants and recognised good drainage and shelter from winter wet weather would be key but that is as far as my planning would go. For the first couple of decades I was busy at work and wasn’t able to put in the effort of looking after small but hardy alpines.

With all that in mind, I made my annual frantic call with some urgent tomato questions to today’s guest, Craig LeHoullier in North Carolina, the NC Tomato Man as he’s known on social media, author of the classic book, “Epic Tomatoes” (affiliate link). Craig knows more about these cherished fruits than almost anyone I’ve ever met. He even shares that in live sessions each week on his Instagram account where you can ask your questions and get solid answers. I asked Craig how he’s doing and what we should all be doing to bolster a bountiful harvest and also about which fruits to save next year’s seed from anyhow and other tomato questions. Read along a

Want to add a tropical flair to your garden this spring? Elephant ears will add a bold statement to a filtered sun or high shade spot. These striking “drama queens” of the garden may be either in genera Colocasia or Alocasia. The easiest way to tell these beauties apart is that colocasias (Colocasia esculenta) will have leaves that point downward, and alocasia (Alocasia species) leaves will point upward. Depending on the species or cultivar of each genus, the size can range from 3 to 10 feet tall and 2 to 10 feet in width. Both types of elephant ears are native to the tropical regions of Southeastern Asia.

(Note on Gallery: Clicking on a thumbnail gives you a large, higher-quality image.)Winterberry hollies are native to swampy areas from Canada south to Florida, from Wisconsin and Missouri east.  Despite their heritage in wetlands, I grow my plants in normal to dry soil, at the edges of my hilly outer fields. I just don’t have wet lowland to offer on my windy hillside.Though they’ll fruit much better in a moist year than a dry one (as with all fruiting plant

THE LATEST BOOK GIVEAWAY–which was a smashing success–ended at midnight Sunday, but there’s a “win” for everyone, it turns out. Collaborator and author Katrina Kenison and I asked commenters to tell us about books they’d relied on in times of transition…and wow, did they ever.

Dr. Tripp, the voice of Robin Hood Radio’s newest program, “Your Health,” received her D.O. from the University of New England. In previous incarnations she has her BS and MS from Cornell; her Ph.D. from North Carolina State University, where she also served as Curator of Conifers for the famed J.C. Raulston Arboretum, and did postdoctoral work at the Arnold Arboretum of Harvard University. She knows from trees and shrubs—and that’s what we talked about:q&a: great trees for gardens, with kim trippQ.What woody plants always got your recommendation—what did you try to encourage clients to plant when you were making gardens for people, while supporting yourself through medical school? A. The first thing I always did, especially with a new client, was to walk around with them and say, “Let’s just see what’s growing here now–what’s out there and doing well,” and have a look at it and see if we like it or don’t. And we’d go from there.I found a few plants in our region that no matter what the conditions, were always doing well—even with deer browse.They were thi

My choice was the Chaenomeles named ‘Cameo’ (above photo) as this double-flowered cultivar is called. It is variously identified as Chaenomeles x superba (a hybrid between the Japanese species C. japonica and the taller C. speciosa, a Chinese type, says the Missouri Botanical Garden) or simply C. speciosa (by woody plant expert Michael Dirr, author of the industry “bible” of woody plants). Dirr says it’s one of his favorite quinces, and “a long a prized plant in the Dirr garden.”Of course nobody agrees on the habit or size of ‘Cameo,’ either, with wholesale nursery Monrovia calling it “good for a mounding groundcover or on a slope,” at a mature size of maybe 3 feet high and 5 wide, about what Missouri Botanical lists. Nonsense, Dirr apparently believes, writing that it’s twice that. Hardiness? The opinion poll says Zones 4 or 5 to 8 or 9.As ever, with this kind of conflicting “expert” help, it’s a wonder that gardeners ever know where to place a plant or how much ro

David Mattern, who oversees the vegetable garden at the splendid public space called Chanticleer in Pennsylvania, is my latest target. You may recall that last fall, David helped us take a critical eye to our vegetable gardens as we took them apart during cleanup, and challenged us also to consider tilling less in the year to come for improved soil health and fewer weeds.David is a graduate of Longwood’s Professional Gardeners Training Program, and after that interned in England at some prestigious spots including West Dean Gardens in West Sussex, with its famed walled vegetable garden.He rejoined me on the January 9, 2017 edition of my public-radio show and podcast to h
