I was given a beautiful Princess Flower about 3 ft. tall in full bloom and planted it on north side of house with some sun. It has been dying stem by stem...first, the leaves wilt and then turn brown...then another branch wilts and turns brown. I have lost about half my plant this way and feel it must have some disease that is not apparent by looking at it. Can you give me some advice which will treat and save this plant. I know all about over-watering, etc. and I know this is not the cause of its decline. I am a senior with many years of growing experience. Thanks very much.

I like to call it "princess Flower.I have had one for about 3 years,almost 4 foot tall.I worry about it in the frost months.I have tried miniture xmas lights.The results are not what I want it to be.Just before spring,I will cut it back to where the stem is fresh and has a few good leaves.It rebounds nicely.

The Tibouchina urvilleana - also known as 'Brazilian Glorybush' in New Zealand - is a vigorous-growing, evergreen shrub. The deep violet-purple flowers open over a long period from Summer through to Autumn, and give a wonderful display in any garden. I planted one in my new garden, and it flowered in its first Summer season. When frosts are expected it needs to be protected.

I bought this plant from a road side stand in NJ. I live in Pa. It was a little bitty thing, just about one foot. Now it is almost three feet tall with blooms every day! Absolutely beautiful. I did not know what it was when I bought it, but the road side stand had a huge tree, almost 6 feet with flowers abundant! Right now I have it in a pot on my deck. Does anyone know how to care for it during our Pa winters?

Interestingly, I once knew a guy who grew this outside permanently in UK, he was near Liverpool UK, he would protect it in winters and he managed to keep it either evergreen, or semi-evergreen depending on the winter. It's more of a challenge here before winters are wet and cold, rather than the dry and cold in USA, and despite an average minimum of only -3 to -4C each winter, it can still present problems. Still with a little protection and care, this plant cant make it through even the most inclement conditions.

I got one today we'll see how it goes, at the moment it's in a pot and most likely it will sit in the greenhouse this winter.

Update March 2017: We've had this in the ground now for two years, in a sheltered area (though still exposed to rain, wind ... read more

Beautiful plant, non stop flowers.I have it as a houseplant in my apartment. Easy to take care of, only problem doesn't like to be moved around. The summer is coming but our night in Canada fresh in June. So I was trying to put it outside during the day and pull buck inside at night. It did not appreciated my effort to give it some natural conditions, prefers to stay where it is. But in my opinion this plant worth an effort to keep it happy. Flowers last only for 1 day but next day another one is coming.

This plant grows very well here in SoCal's mild climate, but does much better along the coast than inland where frost is more prevalent. I bought two small 5gl at the beginning of spring and they took off immediately. Some people train them as patio trees which is what I plan to do. The only downside that I see is that they tend to get leggy if left untrimmed.

indoors - no rooting hormone needed. Winter was milder than normal - lowest temps 3 nights @ 17f. This plant survived winter w/light mulch and the lower branches are already forming new leaves. It is definitely hardy to at least zone 8b, and it's a great addition to perennial gardens in the SE US.

I have a really dear friend who runs a small flower nursery from her home here in northeast Georgia. Several years ago she came across only a few of these Tibouchina plants. She gave me one and told me it was a tropical plant and to take it home and plant it just to see how much success I had with it. It has done really well here. I've realized since then that you do NOT see these plants around here anywhere! You can't even find them to buy unless it's online. They are such amazing, beautiful plants. I really do wish they were more readily available in this area. I would love to have one of the trees also. I enjoy mine so much. So if you see one of these pretty ladies just sitting there, my advice would be to GRAB it !

I live in Merced which is zone 9. If you can get it planted right after the frost is over, it will establish enough so that when it dies to the ground in winter, it can shoot right back up and bloom the next spring.

Tibouchina urvilleana and its relatives should never be planted in Hawaii. I have spent hundreds of dollars and countless hours of time attempting to eradicate it from my one acre homesite in Volcano Village, Big Island, Hawaii,elevation 4,000 '. It smothers everything in its path and is a serious ecological threat to native species of plants and the native birds they depend on. I have had to resort to using power herbicides to keep it under control. In our area it spreads not only by seeds but by underground runners. Please, if you are living in Hawaii never, ever, plant Tibouchina.


On Apr 6, 2010, atisch from Alameda, CA (Zone 9b) wrote:

Princess Flower is one of the most planted and beautiful flowering plants (shrubs/small trees) in the San Francisco Bay Area. While almost always in bloom, the plant itself is extremely attractive even when it isn't, as new growth takes on a wonderful crimson cast. It can easily be trained as either a bush or tree-like form. The most beautiful specimens are periodically pruned as wild growth can get leggy. It needs fairly heavy watering during the first year and seems to need average water thereafter especially when its feet are in the shade of a low-growing, evergreen perennial, for example azalea. Easily reaches 8 feet or more in a few years.

I personally find it misleading to give a negative rating after planting it in Hawaii. It has been known there as a "noxious weed" t... read more

I bought a small Tibouchina two years ago, and in my Zone 7 garden, it stays outside after the danger of frost has passed, and comes inside for the winter. I am in the process of pruning it to be a standard, and keep it in a large pot (18 inch--equivalent to five gallon, roughly). When I brought it in this year right after Thanksgiving, it was still blooming generously. I winter it over in an uninsulated-but-attached glass porch. It is a lovely plant. I didn't get around to pruning it this year until I brought it in, and I am interested to see if any of the cuttings thrive in the cold. Not the recommended schedule for propagation, but it doesn't hurt to try.

This a great plant, I have several in my north central Florida garden. I picked mine up from Lowe's for $0.50 each as they had been neglected and left for dead at the end of last year. These are good plants for a partial shady area of your yard. They have velvety soft leaves which contrast well with the vivid large purple flowers. Semi woody stems root easily in damp soil. This year we had 2 back to back nights with lows of 21oF this knocked my princess flowers back to the ground. They rebounded this spring and are now4 feet tall and starting to bloom. For other north Florida or zone 8 gardeners the blooms on this plant, makes it worth a shot.

In 2005 on Mothers' Day I visited a Rutgers University Agriculture garden in New Brunswick, NJ. Every woman who made a purchase or asked for the free plant for being a mother was given one of these plants in about a quart pot. It took me some searching before I could ID it and get information. But it did grow nicely for me and even had one bloom when left outside and forgotten into the fall. I brought it inside and nursed it through the winter. The next year it grew quite large and flowered beautifully with intensely colored blooms. I brought to Florida to live out its life in a warm climate, and kept dozens of cuttings. Only one has survived and is about 4 feet tall. I am hoping it will begin bloominng soon. And soon I expect I will have to think who will be willing to adopt int... read more

I had 2 princess flowers growing in containers. Last winter due to my Mother being gravely ill, I did not have time to bring them in or cover them during the coldest night we had. Unfortunately, they did not return in the spring. I am hoping that they are providing my Mother with beautiful blooms in heaven. While in Maui in October, I observed many huge plants growing along roadways and in many other areas that receive lots of rain. Later I learned that anyone seeing them should phone in their location so they can be destroyed by the Agriculturtal Department. They are introduced native plants in the Hawaiian Islands and Puerto Rico.

I have spent a good part of the past year trying to eradicate this invasive plant and its cousin, Puna rose (Melastoma candidum), from my acre lot in the Puna district of the Big Island of Hawai'i. It threatens our native forest of ohia and hapu'u (tree fern), and exemplifies that the term "noxious weed" is relative to one's environment.

A nursery I trusted sold it to me and didn't let me know that it could grow as high as 12 to 15 feet and I don't see myself getting this in and out each Spring.

My Princess Flower is budding and blooming prolifically and is so beautiful. It is in a large pot on my patio with afternoon sun and almost nightly rain. At 5,000 ft elevation on Lake Chapala in Mexico (100miles from coast...35 miles south of Guadalajara) this wonderful plant thrives down here (70-75 degrees in summer...60s in winter. Such a deep rich velvety royal purple. One of my favorites.

We moved from Memphis where we had this plant in our front yard two years ago. Upon the move, we dug it up and brought it to the Durham, N.C. area and replanted it. Last year, it did not bloom but got about 3' tall. This year it is coming back with the velvet green leaves. It has been planted in full sun with minimal care. Mulched with pine straw. Will update as to blooms. It is beautiful and quite showy when it does bloom. It has survived two winters in this area. The other night we found that Home Depot had two of these for sale.

I have several of these plants. They survived winter temperatures this year as low as 28 F on a few nights with some protection from hay mulch around the roots (I am on the borderline of Zone 8b/9a). There seemed to be more damage from cold winds than the cold itself: some plants were partially frost damaged where exposed to wind while branches lower on the same plant and out of the wind remained fresh and green. I propagate the Tibouchinas easily by cuttings. When I prune them to maintain a shape (they can tend to get somewhat "leggy"), I just stick the pruned cuttings into moist soil around the mother plant and let them root if they choose. They bloom for me in both sun and shade. The flowers, even if short lived and not plentiful at any one time, provide a deep, vibrant blue/pur... read more
