This is a gorgeous shrub in all seasons here in Atlanta. Mine came with the house, and I've never had to feed, water, prune, or divide it in 15 years. Blooms in January, before pretty much anything else, followed by fabulous clusters of blue berries. In summer it's just green, but the leaves are interesting-- leathery ovals as big as a child's hand, with pointed spines like holly leaves, but not as fierce as holly. The trunks are like nandina, woody, and each branch ends with a horizontal spoked wheel of leaves. Vivid scarlet leaves in fall/winter are possibly even prettier than the fruit in spring. I never get seedlings under the plants, but they do pop up in the lawn under other trees, so probably dropped by birds or squirrels. The lawnmower takes care of those, I guess, because I nev... read more

We have fields were this plant has taken over and we very much wish to remove it permanently and wonder how we can do this as it is very tuff to try and pull out. We need something that can be applied either by spray or ? This is very invasive and would recommend anyone planting it to be very aware and carefull. Can someone give some advise on how to permanently get rid of it? Thank you

My mother had several Mahonia plants in her back yard in Greensboro, NC and I've also grown it when I lived in SC. I used the branches, blooms and berries in flower arrangements. ...Never knew the berries were edible and wish now I had known back when the plant was so available to me!
I now live in Hawai'i and haven't seen it growing here at all.

I love this shrub, as its very easy to grow and relatively low-maintenance. I planted a half-dozen in various locations around my yard (getting anywhere from 1.5-5 hours of direct sun per day), and they do well in just about all lighting conditions. One of mine gets 5 hours of direct afternoon/early evening sun and seems to thrive in that spot (with weekly water in the summer). You'll want to plant these in soil that drains reasonably well, but they're otherwise not that picky about soil type. If you have dry summers like we do, give them a weekly watering and they'll be fine.

The small yellow flowers are unremarkable, but birds LOVE the blueish-purple berries.

Noticed several of these plants in full bloom as I was driving through Syracuse, NY today - it's 4/22/12. All appeared to be in full sun, and most in unsheltered areas, but I didn't take note of the exact direction. I have also grown this plant in Dallas, Tx, but it required shade there.

Take note, the leaves of these plants are sharp and will draw blood if you're not wearing gloves. Not recommended for high traffic area where dogs and people roam. They may not walk into the bush, but the dead leaves that have fallen are still sharp.

Have two plants which have survived several Chicago winters. Have to build bamboo and burlap teepees over my Rhododendron and Azalea to protect against deer, so the Mahonia gets tented also. One Mahonia is on the south edge of a treed area, the other is back in the shaded area of the same trees. The south facing, right on the lawn edge, has been growing better than the 'in shade' one, but both are doing well.

When young, and during a severe winter, the deer 'chowed-down' and nearly killed the plants. Thus, I have been protecting them. Our deer do not seem to realize that they are not supposed to like Oregon Grape leaves....they eat anything.

Planted one in a VERY sheltered location on the NE corner of my house and still had some die-back. Leaves stayed green up until Spring when most of them fell off. Every one of these I have seen planted in the North is absolutely fried if it is not planted in a sheltered area (NO wind).

Last year I planted Oregon grape in the shady area between our house and the next. It was a single-stemmed plant when I bought it, and it grew to about 4 feet high in two growth spurts in summer.

It stayed dark green for most of the winter, but when the snow started melting, the leaves that were above the snow (about 2 feet deep) began to turn tan and fall off. The upper part of the stem is dry and somewhat shriveled. Apparently only the snow-covered part survived the winter.

Two tiny leaves below the snow line are still green. Some sprouts are emerging on the lower part of the stem. I guess this year the plant will turn into more of a bush. Hopefully there will be enough snow next winter to protect it... without snow it doesn't seem to be really hardy. Hopefu... read more

I have a large, and very tall, patch of this in my Eugene yard, growing in full sun. I like the long period of yellow flowers, and so do the birds and bees. It was allowed to run wild by the previous owner, and can take over if not controlled. I seldom water it, yet it is healthy and vigorous. I don't like the prickly leaves, but with the tall variety, this is less of a problem, because they are easier to avoid.

I have planted 5 plants. Four are doing well but one just does not thrive. It is small and weak. They have been in the ground for about 2 years. I do not know if there is a disease or what. They are in the same spot, east side of our house at the front. They have morning sun and afternoon shade.

Oregon grape grows wild in Northcentral Idaho. It makes excellent tasting and beautiful jams and is a pretty plant all year. I don't find it aggressive at all. It prefers at least some shade and grows in total shade here.

This plant grows wild in wooded areas all around Idaho. We're at 2,700 feet, and I've seen it in the mountains much higher than that. I have several volunteer shrubs in my own garden, growing in dry, almost-full shade. They had a lot of flowers this Spring because of the wet winter, and now there are lots of berries. The problem is that it's nearly impossible to get rid of! I am constantly having to pull out volunteers with deep, extensive root systems all over the shaded areas of my garden. I like the fragrance of the flowers, and this shrub is certainly care-free, but I do not want a garden full of Oregon Grape. I'd say be careful where you plant it, and be sure to keep it in bounds, or you may have a lot more Oregon Grape than you planned on!

The first three of our four years in Payson, Az, our Oregon Grape Holly was visited annually by the single-note-calling phainopepla in summer for the grapes. I thought the fruit was bland. The blossoms before are very aromatic, almost cloying. Our O. G. H. are being infested with a web making insect similar to the tent caterpillar. I've had to raze a couple to the ground. They do put up shoots elsewhere, so I don't think their in danger of elimination. I just wish I knew what the insect is.

I've had this plant for fifteen or twenty years at 1100 feet in the northwest corner of Connecticut and it's as carefree as anything can be. It's in complete shade until late afternoon, spreads very slowly, and comes back when we thought it was dead. It's still barely two feet high but six feet wide. We clip it occasionally for holly decorations at Christmas.

A very hardy plant, not just in terms of temperature. The previous owner of our property went through and sprayed everything with RoundUp, and we were sure the Oregon Grape was dead. To our surprise, is wasn't!

Says full sun... according to conventional wisdom around the Willamette Valley, it's a shade plant. It's very rarely seen growing in full sun around here. Our patch grows in full dry shade, and is thriving.

The yellow flowers are rather ugly up close, but stunning from a distance. The berries are a little too tart to eat straight, but make a wonderful jam. A must-have for the PNW.

It is outstanding in shade with red folliage in fall, bright yellow blooms in spring and olive shaped dark purple blue fruits in summer. An interesting shape, very hardy, not needing maintenance. Goes with azaleas, but will stand even less light.

I just moved into this new neighborhood in Hope, BC Canada, in December. One of the first native plants to pop up in the area (in Feb.) is the Oregon Grape. They grow everywhere around here! I can't wait to see the fruits and flowers..It is a very woodsy area around here, lots of shade under large trees, but alot of heat and sunlight in summer. They really seem to thrive under the canopy of trees, with all of the natural mulch.....

This plant varies from a stout shrub with many erect stems to a creeping form with an underground rhizome. Shiny holly-like leaves and chalky blue berries identify this plant common to pine forests of western Canada, northwestern CA, NV, TX, Co, SD and western MT.

Native Americans used the bark to make a yellow dye. The berries are eaten by man and beasy alike and they make a nice jelly.

Yes, of course it grows here! This is its prime growing location. It grows on the north slope around my house (on a north-facing scarp) but you won't find it growing naturally in the open sun-baked flatland or on western or southern exposures unless somewhat shaded. It's extremely hardy. I'm at an elevation of of a little over 4,200FT and it grows way up higher in the mountains around here that can get 6'+ of snow in the winter. In addition to that, here in the Klamath Basin, the moisture content during the winter is basically nill when the wind blows and the temperatures go below freezing.
