Snowdrops and crocuses flower while hostas are still dormant. Tulips and daffodils begin flowering just as hosta foliage is emerging. As the hostas grow, they cover the spring bulb foliage. For summer interest, shade-loving annuals such as coleus, impatiens and begonias complement the hosta hues.f your hostas are in a pot, just plant the pot in the garden, making sure the rim of the pot is slightly below the surface of the soil. You can also store your hosta containers in an unheated garage, shed or cold frame.
