Much smaller than their conventional cousins and with an exterior that makes them look like bright red mini hand grenades, alpine strawberries are unusual-looking fruit indeed. Their taste, however, is exquisite; packing an intense sweetness unmatched by regular strawberries, which is why it is said that the alpine variety makes the best jam. If your backyard is rather more limited in size than a botanical garden, or you are growing from pots on a balcony or patio, they are also a far better bet. Easier to cultivate from plants rather than seeds, they will flourish in most soil types but appreciate a good dose of moisture and nutrients, so be sure to top up their soil with a regular layer of compost.
