We had a colder than usual winter in 2017 and tree was totally unaffected. Definitely hardy in z9a. Sweetly fragrant white flowers in Spring.

I planted 2 Stoppers in a narrow strip between my driveway & a concrete footing... they get blasted by full, Western sun reflected off pavement.
They are rapidly becoming my favorite shrub/small trees; blooms are sweetly fragrant, red berries are interesting & birds eat them, and the bark is beginning to develop twisted, flaking, reddish character, and are now 10-12 feet tall. Best of all, the plants have a faint nutmeg-spicy scent (even without crushing the leaves) which greets me when I park beside them! Two green thumbs up!!
June 2020 - During COVID19 lockdown, it cheered my day to watch a mockingbird fight a pair of red-vented bulbuls for the berries.

We planted a simpson's stopper a few years ago. The yard people have been shaping it like a round shrub and this year I stopped them. I only trimmed the lower limbs point down and fertilized. In just a few mths I have 12" shoots straight up and have fallen over with rain and wind. I wonder if I should trim them shorter? I am trying to make it look like a tree and grow into a nice shade tree. The berries weigh branches down too. So now it looks rough and I don't know what to do!

I gave this one a try here in Eastern Maryland (zone 7) after finding a cheap small one for sale. I not only expected an average winter here to kill it but then it ended up being the coldest February in history for this area. Many nights were below 10F and about 5 were consecutive with the lowest temps around 4F on back to back nights. The leaves remained evergreen until temperatures got below about 15F. By the time spring arrived it had completely died above ground, but to my surprise it began to regrow from below the mulch and recover. The next winter was another cold one that also killed it above the mulch, and like the previous year, it recovered in spring. These seem to be a little hardier than usually given credit for. I wouldn't recommend growing these here since they seem to ... read more

This plant is definitely winter hardy into Zone 8b. It's come through winters with lows into the upper teens and low twenties without problems at all.

Simpson has been in my front yard for 3 years, and I've been trimming it into a tree, about 6 ft tall. Up until about a week ago, it has been gorgeous. This year it was loaded with flowers, and subsequently, berries.
Recently the branches sagged when we had heavy rain. I thought Simpson would come back on its own, and it did somewhat. However when the berries continued to grow, the limbs sagged again, so yesterday I trimmed many small branches that were excess or crossing, thinking the reduction in weight would allow the remaining main branches to come back up.
This morning, three good-size branches were broken off the tree -- on the ground. Branches have never broken off before and I wonder if yesterday's trimming weakened instead of strengthened the tree. Any tips on exac... read more

When you first plant it ,do not over water... After 3 months it had flowers. Great plant..

Technically, this is a "Simpson Stopper," not a "Simpson's Stopper." That aside, ours is a very manageable size and is easy to keep in bounds. It flowers regularly and has no pest problems whatsoever.

I have a zone 8b garden in north Florida near Gainesville. Two years ago I planted two Simpson's Stoppers by my carport under high shade. I watered then a little for a month or two, then proceeded to ignore them. They did not grow much the first year, but have grown close to 2 feet in the last year after establishing a root system. We had a very cold winter last year, with temperatures falling to 16 degrees F (on an accurate thermometer less than 10 feet away from the plants), and they were untouched. No flowers yet, but I'm still hopeful.

As a sidenote, they were planted adjacent to some existing boxwoods and the location has provided me with numerous opportunities to compare the two plants. I must say that I much prefer the look, feel and graceful habit of the stopper! Th... read more

Simpson's Stopper is native to South Florida, the Keys and the Caribbean. This flowering and fruiting stopper is a member of the Myrtle family. It makes an ideal landscaping plant that needs little care. It is a dependable bloomer, as well as a favored nectar and fruit sources for many animals.

Its aromatic blooms appear regularly throughout the year. Butterflies and other nectar seeking insects are attracted to the flowers. The showy flowers are small, white powder puffs. They appear in masses that resemble foam.

Small, reddish-orange fruits follow. These edible fruits have a sweet, citrus-like flavor. Mockingbirds and other fruit eating birds relish therse berries. The name stopper refers to the traditional use of the fruit and bark as an anti-diarrheal.... read more
