hot plant: stewartia, an ideal small tree
I LIKE PLANTS THAT EARN THEIR KEEP. By that I mean they do more than a week or two of showing off; they look good in more than a single moment, or season. The small-ish to medium trees in the genus Stewartia are a good bet if that’s the kind of multi-season interest you are looking for. Sound good?
The Latin specific epithet, or species name, of the Stewartia I grow is pseudocamellia, which roughly means it disguises itself as a camellia when in bloom (a nod to the look of its lovely and plentiful white June-into-July flowers, and the fact they are very distant relatives in the Tea Family).
But this Stewartia, from Japan, which gets to maybe 25 feet or so in a Northeast garden setting and is happy in part shade or sun, isn’t content to offer up just nice flowers for the privilege of living with you. It gives you peeling, lovely bark all season long (below), and hot fall color, too, as the leaves eventually change. I should warn that it grows slowly, so this is an investment piece, not instant success, and adaptable to Zones 5-8.

What I insist is that you at least agree to look at Stewartia next time you’re in a good woody plant nursery and think of this: What other garden-scale tree gives summer flowers (preceded by showy marble-size buds, bottom photo, by the way, in my pseudocamellia); hot fall foliage, plus winter interest in the form of textural bark and lovely structure?
Guess after reading this you already know the answer to today’s quiz, huh?


i guess I’m an imprudent gardener as I am now replacing the 6 bradford pears I bought 35 years age and lost recently with 6 Stewartia pseudocamillia, inspite of the fact that Dirr says they are not street trees. These Stewartia are all single trunk and seen perfect for my corner location in southern Long Island. I am thrilled to find your website as no nursery in my area carries these trees and I have not found much info on them in books.
Hi Margaret. I’m impressed that you are still responding to comments after 15 years. I have had so little luck with stewartia over the years (decades!) that I have been reluctant to go down that path again. But 5 years ago I moved to a small farm and am turning it into my own personal arboretum. I have planted well over a hundred trees, and decided it was time to give stewartia another chance. Last spring I planted a Ballet that was a 6-7’ ten gallon specimen, and this spring I managed to acquire a large B&B Scarlet Sentinel. I guess it is an indication of how low my bar had been set that I was excited when April rolled around and the Ballet was still alive with no dieback. Funny thing, though. I am in central NY, and we had weeks of very cool weather, and day after day of gentle rain. All of my friends and the local farmers hated it, but it was ideal for the kind of gardening I do. Since April, the Ballet has grown roughly 4 feet – not fake news – and pushed a dozen or so flowers. Perhaps even more impressive, the newly planted Scarlet Sentinel showed no signs of transplant shock, and is covered with dozens of flowers as I write this in mid July. Everything I read, including your original article from 2010, indicates that Stewartia are slow growing, and multiple web sites mention that it often takes years before they flower, so patience is a key. And again, I have planted and lost several in the past. As sad as the reality of climate change might be, I think the weather this spring and early summer might well be the reason that my two Stewartia are doing so well. The Ballet gets quite a bit of sun and then late day shade. The Scarlet Sentinel gets a few hours of morning sun, but is in heavy shade the rest of the day. Given that it is on the edge of woods, I am a little concerned that it is in too much shade, and I am planning on pruning a few branches overhead to give it maybe another two hours of direct sun. Thank you for posting here. You gave me the kick in the pants I needed to rethink Stewartia in my garden. So far, they have been wonderful.
I luckily have a single trunk Stewartia pseudocamelia in my garden and there are multiple buds every spring. However before they are able to bloom the squirrels eat them. I enjoy the squirrels in my garden but is there a way to prevent them from taking the buds? Someone suggested a solution of garlic or hotsauce. Any thoughts?
Thanks,
Trish
Hi, Trish. They eat all the buds off my ornamental Asian pear espalier here and various other things and it makes me crazy. I have never tried spraying the buds but that would (on a tree) mean climbing a ladder and re-climbing every so often after weather to reapply and so on — so doesn’t seem very practical. Most recommendations are to wrap the tree and so on with landscape fabric or mesh — but again, not very practical (and ugly!). I’m afraid I don’t have a solution other than paying a licensed nuisance wildlife handler to relocate the culprits, which some people do.
I have a new stewartia and it is about 18 feet tall. It has quite a few dead branches – not all at the top – just all around. Should I cut them off and if so when?
With the “3 D’s” — dead, damaged or diseased branches — it’s always fine to remove them when they occur, so yes, go ahead and clean it up.
Just planted a 4’ Stewartia. How often should one water. What is meant by water regularly?
Very helpful finding your blog while considering Stewartia Mondelpha after seeing a gorgeous specimen in the winter garden at UW’s Washington Arboretum. I’m considering it against a tall front of house wall facing East in Seattle suburb. The sopt is roughly 15′ x 12′, morning sun, driveway on 2 sides, house on a 3rd. Would you be concerned about the roots near the house or driveway? Suggestions for obtaining a multi trunk growth from near grond level, or maybe that is the natural habit? Any other thoughts or advice much appreciated.
I think it depends if there is enough room for it “someday” when it is at least 15 feet wide and 30 feet tall. Like I’d probably want to place it 12 or so feet from a building so that even when mature (and each side is half that 15 wide) there is still breathing room on that side. Not sure your space sounds like a big enough footprint.
Thank you! If I consider another spot, how are the roots near driveways or foundations?
I purchased and planted professionally two years ago my Japanese Stewartia. The first year it blossomed well for a newly planted tree the second year it was coming along until the Japanese beetles exfoliated seventy five percent of the tree late June. Some leaves did grow back over the summer. This year it has hardly any leaves mostly on the bottom, it does have buds but still not open it looks like a large stick in the ground. The bark has started peeling nicely, more since last fall. It has been very dry here in PA. less then an inch of rain last month. I do water it regularly ever since it was planted. It is quite tall around fourteen feet an multi-trunk. Any suggestions what could be happening with my tree? My husband says it looks dead to get rid of it. It was an expensive tree and when healthy it was beautiful the first year.
I would start by contacting the place you bought it from (you say it as planted professionally) and let them know your experience. It does sound as if the multiple insults — something that hadn’t had time to settle in, really, then being defoliated by beetles and then assaulted by drought — may have been too much for it. It should be fully leafed out by now for at least a couple/few weeks, I would think.
Please tell me where I can order a Stewartia monodelpha ‘Nana Compacta’, ideally a multi-stem or low-branching single-stem specimen with a vertical (NON-pre-Bonsai) trunk?
I don’t know, Edward, and did a search online that didn’t turn up any places. When there is something special I want I go to the very best woody plant nursery near me and ask them if they can source it, since they have all the wholesale catalogs of great growers around the country. Worth a try. Sometimes it takes a year to track it down, but I have gotten some unusual things over the years that way.
