Amaryllis (and their hybrids) are winter growing, hence with exposed leaves in winter they need to be planted in a sheltered site where they are unlikely to be chilled below about -4°C e.g. a cool conservatory should be fine, with the pots moved outside in the early spring. A summer baking in dry conditions ‘ripens and primes’ the bulbs for flowering. In favoured spots it might be possible to grow them successfully outside.
