(flowering onion), Allium sphaerocephalon (drumsticks), Anemone blanda (Greek windflower), Anemone coronaria (poppy flowered anemone), Anemone x fulgens (scarlet windflower), Arum italicum (shade) )Italian arum), Babiana (baboon flower), Calochortus (mariposa lily), Chlidanthus fragrans (perfumed fairy lily), Cyclamen hederifolium (shade) (hardy cyclamen), Cyclamen persicum (shade), Crocosmia (montberia), Crocus imperati (Italian crocus), Freesia Galtonia candicans (for summer color), Gladiolus x hybrida (Gladiolus), Hyacinthoides hispanica (Spanish bluebell), Ipheion uniflorum (spring star flower), Iris xiphium (English/Dutch iris), Ixia hybrids (corn lily), Lachenalia aloides (cape cowslip), Leucojum vernum (spring snowflake), Muscari armeniacum (grape hyacinth), Ornithogalum arabicum (star of Bethlehem), Ornithogalum narbonense (narbone star), Ornithogalum thyrsoides, Oxalis purpurea (cape sorrell), Ranunculus asiaticus (ranunculus), Scilla peruviana (Peruvian squill), Sparaxis tricolor (Harlequin flower), Triteleia ?Queen Fabiola? (brodiea), Tritonia crocata (flame freesia), Veltheimia bracteata (shade) (cape forest lily) and Watsonia (bugle lily).
I'd plant the bulbs in drifts so you have waves of color in the garden. You can also take into account which grow the tallest and place them in the back by the fence, placing the shortest in the front. To cover the fence behind the bulb garden you can use an annual vine which you replace each year (sweet pea, scarlet runner bean, etc.) or plant a perennial such as honeysuckle, clematis or passionflower.
Enjoy your garden!
