Unusual Bulbs Spice Up the Garden
By Marlene Willis
Gladioli, dahlias, lilies, begonias, elephant ears, cannas and calla lilies are among the most popular spring bulbs. Most gardeners are familiar with these beautiful species and routinely plant them each spring for a beautiful show of summer colour.
But there are many other exotic summer-flowering plants, available in their dormant state as bulbs just waiting for plant enthusiasts to apply their magic touch. With the provision of suitable temperatures and adequate moisture, plants native to countries such as South Africa, India, Mexico and the Mediterranean can burst forth into bloom in the temperate garden.
One of our greenhouse staff, Jenyse Green, used the African lily (Agapanthus) as a feature in this container. Atop the lily’s tall (60-75 cm) stalks were clusters of deep blue, star-shaped flowers. Blue lobelia, vinca ivy and Mexican heather spilled over the edge of the pot, creating an impressive display. Even when the lily finished blooming, the seed head remained interesting and attractive. A similar effect can be achieved by planting Brodiaea instead of Agapanthus, although Brodiaea is somewhat shorter. Agapanthus is native to South Africa and enjoys full sun and well-drained, moist, organic soil.
The Pineapple Lily
The pineapple lily (Eucomis) is another interesting spring bulb, native to South Africa. This is an apt name for this bulb, as a cylindrical stalk of starry blooms is capped with a tuft of green leafy bracts that resemble a pineapple. There are two varieties available: Eucomis bicolor has pale green flowers with lilac edges, while Eucomis comosa has pale pink flowers tinged with green.
The pineapple lily is an excellent replacement for the traditionally used dracaena spike as a focal plant. The flower stalk is attractive, long-lasting and an attention-seeker. This bulb can be grown in the garden or in containers.
If rich, vibrant colours are needed to punch up the landscape, try incorporating some poppy anemones (Anemone coronaria). There are single and double varieties in a wide range of bold colours, most with a contrasting black centre.
These anemones originate around the Mediterranean Sea in southern Europe. They like a warm, sheltered, sunny location and light, sandy soil, and you should hydrate the corms before planting by soaking them in water overnight. Use in borders or containers. The blooms make excellent cutflowers that last about a week.
A Neglected Palette
The selection of underused but gorgeous spring bulbs is vast. Members of Hole’s staff have enjoyed growing many unusual bulbs in their own gardens, including Mexican Shell Flower (Tigridia), Peacock Gladiolus (Acidanthera), Peruvian Daffodil (Hymenocallis), Summer Hyacinth (Galtonia) and Crocosmia, to name just a few. Bring the exotic colours and textures of faraway places home by planting some of these unusual choices this spring!
