When a gardener mentions planting bulbs, the first flowers that often
come to mind may be daffodils and tulips. We plant these types in our
gardens in fall for glorious displays in the spring. But if you are
willing to expand your definition of a bulb, you will find a whole
new season of beautiful blooms and foliage in what I refer to as
summer bulbs. Now technically these plants include true bulbs,
along with tuberous roots, corms, and tubers or rhizomes, but
it is just simpler to use the blanket term – bulbs.
The plants that grow from summer bulbs will add a tropical touch
to your garden. Many varieties have thick fleshy leaves and exotic
flowers, which makes sense because most originate from subtropical
regions such as South American and South Africa. I like to mix them
in with my more traditional annuals and perennials to add a little
flair to my flower borders and containers.
Summer bulbs should be planted in late spring or early summer when
soil temperatures have warmed to about 55°F. In general
they should be planted close to the soil’s surface, about 1 to 2
inches deep. Choose a location that has well drained soil, unless
they are suited to boggy conditions. One of the nice characteristics
about these plants is that many types, such as elephant ears and
caladiums, will perform well in partial to full shade.
True to their sub-tropical heritage, these bulbs thrive in heat and
humidity, but you can also grow them in northern gardens. The trick
is to lift and store them in the fall before the first frost. How
you store the bulbs depends on what type of plant it is. Most are
lifted from the ground and stored in peat or vermiculite in a cool,
To find unique varieties of summer bulbs you may have to go through
a mail order source. The best time to do this is in the spring.
Many mail order sources will offer special deals in late spring, but
don’t wait too late because sales and shipping often end in June.
