Hydrophyllum canadense, I believe.

I am growing a lingonberry bush in Southern California. They will grow, but only if planted in the right place and given consistent water, especially in the summer (note this means a little water every 2-3 days). I have it planted in a partially shaded area that receives a fair amount of sun in the early part of the day. Lingonberries need a fair amount of sunlight, and will wither if you simply plant them in partial shade. But they also easily dry out in the hot sunny climate of Southern California, so full sun can also kill them off in this climate zone. Many of these types of plants do much better in morning sun than evening sun because it is still relatively cool/moist in the early part of the day, and the plant can receive the sun without drying out. One more observation, it is possible for potted lingonberries to survive in a 7+ hour sun location here, so long as they get very consistent water and it is not summer, but they are much happier in partial 4-5 hour morning sun. If your watering habits are a little spotty at best, lingonberries are going to have a very narrow tolerance to sunlight. In conclusion, it is possible to grow them, but it is not a "just plant then forget about it" species here. And lingonberries are probably not going to be as prolific here as they would be in a cooler climate with a little more sun exposure. It's a similar situation with raspberry bushes. quote by hoosierquilt: " I'm pretty sure Lingonberries are native to Scandinavia and therefore like plenty of chilling hours, and Southern California is one of the few places in the US that doesn't get enough chill for many fruits. " I am pretty sure the issue is not about actual chill when it comes to lingonberries. My little bush has already flowered and produced some berries, and it did not even have another variety to pollinate it. We basically do not get any chill here, where I am. But you are right about Southern California, many varieties of fruit tree do not fruit, or do not grow very well here, since there is little to no chill in the winter, especially in the coastal most Southern part of the State (Los Angeles to San Diego) where most people live.

Wondering if anyone in California has tried grown lingonberries? Asked over on the Orchards Forum, but haven't gotten any responses. I know they're mainly grown in much colder climates, but thought I'd ask. I am having such success with my blueberries, I thought I'd at least give these a try. Patty S.

I bought 3 of them at Russell's Garden Center in Wayland several years ago. I forget which kind. Its in my files. they are in afternoon sun slightly filtered. They are pretty slow to do much of anything. Minimal fruit. I first planted them 4-5 feet apart given typical "groundcover" expectations (too much too fast), but I have moved them closer together twice. One of them had a lot of trouble this summer. Maybe voles. Overall, I would give it a 5 based on its lackluster vigor. Maybe it would rate higher if I had it in a sunnier spot. I printed out that article to read. Maybe I can improve its culture. A much more vigorous evergreen unusual groundcover is paxistma canbyi. Love it! no fruit or flowers, but tough little evergreen groundcover with the tiniest cutest leaves. I also have a cranberry groundcover, same family. It does better but it is in a totally different spot. damp, rich, acid soil in sun. Maybe I should move one of the lingonberries to that bed. I bet it would do better.
