Offset Bulbs: One of the most popular ways of growing offset bulbs—snowdrops, daffodils and crocuses, in particular—is to naturalize them in drifts so they spread at will. This is usually done in grass, but those offset bulbs preferring shady woodland conditions can be naturalized in soil under trees and shrubs. It is also possible to establish offset bulbs beneath a planting of ground cover like scrambling ivies.

belong to the genus Capsicum, native of the American tropics. The seed pods of okra or gumbo [B] are picked ten weeks after planting.
Small offset bulbs such as grape hyacinths (Muscart) and scillas are often grown in rock gardens or used to make carpets of spring color beneath taller plants. Because spring-flowering offset bulbs die down in summer they can be used effectively with deciduous shrubs, which are bare of leaves when the offset bulbs are growing and flowering, or with herbaceous plants, most of which will hardly have started to grow so early in the year.
Winter aconite (Eranthis), snowdrops, crocuses, scillas, chinodoxas, muscaris, and daffodils are all particularly recommended for this kind of two-tier planting, as they do not have to be lifted every year but can be left undisturbed for several years until they become overcrowded. |
