Or, you can plant bulbs that will flower next spring when the seasons cycle around once more. I find that allotting about 15 per cent of the space in a flower bed to annuals and bulbs is a reasonable portion. For me there are no great howling gaps when the annuals go by, and the bulb foliage one is to encourage, up until it vanishes, does not flaunt its fading, aging charms in too public a manner. My problem is deciding on which bulbs to plant. Tulips have a rainbow array of colors to choose from, but are decidedly NOT deer-proof.
Hyacinths are deliciously fragrant.
Snowdrops should be planted with a lavish hand, scattered under trees in generous numbers to welcome the very first days of spring. Pooh, I'll just plant them all. There's always a corner that would be improved by planting bulbs. Try it, next spring you'll be pleased you did when your impulsive plantings burst into bloom. Clean the garden, and put it to bed.
