Avoid the hottest afternoon sun. The smaller-leaved varieties such as 'Needlepoint' or 'Hahn's' are preferred. Ivy makes a great indoor plant if it is washed off periodically to prevent spider mites, and can be kept outside in morning sun or the shade of a tree. It is completely hardy in our climate, so it can live outside year-round. Ivies can become invasive if planted in the garden, so keep them in pots.
Amaryllis naturally bloom in the early summer.
These bulbs are produced in Holland and South Africa. Those from South Africa think they are in the summer, being from the Southern hemisphere, and will bloom right away. Give Amaryllis water every few days until the bloom is done. Cut off the spent bloom spikes and allow the foliage to grow indoors until frost danger is past. I've had my best results simply planting these in the ground in partial shade or full morning sun, in average soil.
