When summer comes, there is almost an embarrassment of riches, particularly among the Lilium (Lilies), many of which give scent as well as colour to a room. One of the tallest and most handsome of plants grown from bulbs, the Lily gives excellent value for money because its flowers are long-lasting. Lilies need deep pots, and are at their best in a group of three. The auratum variety (Queen of Lilies) is particularly recommended for growing in pots: huge waxy flowers, several to a stem, are deeply scented and often decorated with distinctive golden stripes and crimson spots. They grow with great vigour and need little care. L.speciosum (crimson markings on cream petals) and its varieties in white, red or pink, and L.longiflorum and its varieties, with white funnel-shaped flowers, are also popular and particularly suitable for pot growing.
Another lily-like flower, easy to grow and deserving a pot to itself, is Amaryllis belladonna (Belladonna Lily), which produces several enormous fragrant pink or deep red flowers. The Amaryllis is frequently confused with the Hippeastrum as they look very similar. There are many species and varieties suitable for pot growing. Flower colours vary considerably; some are bi-coloured at the top of a 11-2 foot stem.

Agapanthus, too, is spectacular, particularly if a group can be grown in one large tub or urn. Sometimes called African Lilies, they have round heads consisting of dozens of small flowers. The best-known variety, A.umbellatus, grows 2-3 feet tall with bright blue or white flowers. Agapanthus needs plenty
of water and fertilizer during summer.
For a more discreet charm, a group of Polygonatum (Solomon's Seal) could grace the corner of a cool room, perhaps among Ferns. P.multiflorum is the best choice for growing in a pot: from each arching stem hangs a row of small greenish-white bells.

Other well-known bulbs for summer include a few varieties of Gladioli, tuberous Begonia and Montbretia. If you want to try something less familiar, look for Brodiaea uniflora (profuse, neat flowers on 6 inch stems, which remain in bloom a long time and smell sweetly), Tritonia crocata (taller, with long-lasting, funnel-shaped, orange
flowers), Streptanthera cuprea coccinae (exotic orange and black flowers borne on 9-inch stems among a fan of sword-shaped leaves), Achimenes (the small, prettily drooping magenta or pink flowers last a long time and the plants multiply every year - a good choice for hanging baskets), Crinum powellii (the Cape Lily - handsome white, lily-like flowers veined with red), and Valotta specioza (at least 18 inches high with several funnel-shaped flowers in bright scarlet).
