Dry Days and Idle Mowers
The number one question for gardeners at the moment is: what is the weather going to do? The much looked forward to rain on Tuesday and Wednesday is fast disappearing from my local forecast.
There is some hope for rain; the long range Met Office forecast states that “Into mid-August more changeable or unsettled conditions probably become prevalent.” Whatever the forecast, do not worry, we are sure to have rain for the August bank holiday.
Whilst there is no grass to cut this weekend this does give time to investigate planting some of the bulbs that are perhaps not the first on our list for next spring. If you are enjoying agapanthus this summer be sure to consider alliums for your spring garden.
Ornamental Onions
The allium includes all types of garlic, onions, shallots, and even leeks. We use the term Ornamental Onions to describe the alliums we plant in our gardens, which encompass a large range of plants, from the small and delicate cowanii to the very large and imposing varieties like Gladiator and Globemaster.
First identified in 1753, classifications have been difficult, but most share the same basic characteristics: a tall, strong stem with a round head of flowers. This quality makes them excellent for planting in a border, as their shape adds structure, form, and an instant draw to the eye. They are a high style look.
Where to Plant Them
There are alliums for all parts of the garden, taller varieties for the border and the smaller species for the rock garden, front of borders, terraces and containers. Taller types circled with complementary smaller varieties can be particularly effective.
They are a favourite with flower arrangers as the blooms are long lasting and can then be dried for use in winter arrangements. Although popular as potted plants in the spring, they will perform far better when planted as bulbs in the autumn. You have a far wider choice and considerably better value for money.
Purple, white, yellow and deep red. Four alliums worth a place in the border next spring.
Planting
Many of the taller species carry their globe like flowers on a leafless stem with the foliage dying back as the flowers emerge. Try planting these in mixed borders and amongst shrubs that only cast light shade in May and June.
Make sure the area around your alliums is kept clear and well weeded to ensure they grow strong, straight stems.
Alliums, like most bulbs, like to be planted in well-drained soil. They prefer full sun but will also tolerate partial shade.
If left undisturbed, they should establish themselves and flower year-to-year.
When planting in the border, and especially important for container planting, it is essential that they are planted deep enough, 10-15cm (4-6 inches). The flower stems emerge from the side of the bulb rather than the centre, and if planting is too shallow, they can tend to flop in exposed positions.
