A burst of colour, April shows bring May flowers
During the month of May, local garden centres are receiving their stock of trees, flowering shrubs, evergreens, roses and perennials – often the best selection you’ll find throughout the entire year. In spring, we want magnolias, Japanese maples, flowering cherries and other ornamental trees and shrubs that offer exquisite blooms. The best quality plants are sold first, so if you’re a late spring shopper, you’ll never know the difference between the ‘best’ and the ‘next best’. In this case, the early bird catches the worm of the highest value.
Plants differ in size, colour and texture. However marginal those differences are to the untrained eye, there can be a marked difference, especially where ‘woody’ plants are concerned. Trees, shrubs, fruit trees and evergreens can vary greatly in their appearance at the time of sale. Any retail garden sales consultant will tell you that they spend a lot of time pulling out products, usually from the back of a row, in order to find the perfect specimen.
Barronwort (Epimedium) | They tolerate dry conditions and almost full shade, they flower for several weeks beginning in May, and they make a great ground cover under a dense tree canopy.
Pansies | We’ve planted pansies as early as the 15th of April. They will take some frost and flower best in cool temperatures (under 25°C). They love the sun (east exposure) and are available in an array of vibrant colours.
Violas | These are more frost- and heattolerant than their larger cousins – the pansy. Neither are reliable perennials, so you may want to treat them as annuals. However, they have been known to overwinter after their first year in the garden. Violas often selfseed with aggression.
Peonies | They’re not early bloomers, but they are among our favourite flowers. It’s well worth the wait (late May or early June) for them to produce an abundance of mop head, roselike flowers. They are reliable, winterhardy perennials that come back year after year. In fact, there are peonies that were planted around pioneer cabins more than a century ago that still live on. The peony is more than a perennial – it’s an heirloom.
Don’t plant peonies too deep. Prepare a hole with generous quantities of compost and 30 per cent sharp sand for drainage. Do not place soil more than 10 centimetres over the top of the highest crown bud on a bare-root plant. Divide in September.
Bleeding Heart (Dicentra) | Plant this old fashioned favourite in a sunny or semi-shaded garden. The hanging pink, or white, flowers of the original varieties are beautiful, but only bloom for a few short days. The newer ‘Luxuriant’ variety blooms for weeks on end, beginning in mid- June, throughout the summer and into early autumn.
Other early blooming perennials include trilliums (nursery grown, never taken from the wild), primula, tiarella, geranium and brunnera. Plan, peruse and then plant in well prepared soil.
