Rugosas are proof against most illnesses, although you might need to familiarize your self with the checklist of widespread illnesses simply in case yours comes down with one thing.
Crowded vegetation rising in moist areas usually tend to have points like rust and powdery mildew.

Like all fruits in the Rosaceae household, the seeds include compounds often called cyanogenic glycosides. These produce poisonous hydrogen cyanide that may make you fairly sick in case you eat sufficient, so don’t eat too lots of the seeds themselves.
They’re robust and bitter anyway, so I’m undecided why you’d need to. If you happen to occur to crunch on a couple of, you don’t must stress. You’d should eat quite a bit to develop into ailing.
As a result of the hips are so massive, you possibly can pick the seeds pretty simply. If you happen to don’t really feel like doing the work, simply boil the hips to separate the flesh from the seeds.
