Strawberry - Fragaria × ananassa

Strawberries are perennials and last for two to three years before losing vigour, but will likely produce runners which become your new plants. It is also best to allow approximately 6 plants per person to allow for enough for everyone, and more if you want to make jams or other preserves. 

Strawberry varieties are usually part of two distint groups, short-day or day-neutral. To ensure long harvest times it is a good idea to plant several varieties. Short-day varieties are good for early spring crops as they start producing flower buds when the days are short, while day-neutral varieties repeat-flowers throughout spring and summer, provided the weather is warm.
