Summer Sky

The Blue-flowered Leadwort (Ceratostigmaplumbaginoides ‘Summer Sky’)is a hardy, evergreen perennial growing about 80 centimetres high and wide.

From mid-summer to early winter it has a prolific display of loose, lacy heads of dainty, powder-blue flowers. During autumn, the foliage takes on attractive autumn shades of yellow and orange.

Summer Sky prefers a sunny spot in fertile, well-draining soil. It looks great growing in rockeries or on embankments, and mass planted it’s perfect to cover low maintenance areas.  

Planted in a decorative container on a balcony or courtyard, Summer Sky adds charm and appeal throughout the year.  

Once established, this easy-care plant is very tolerant of dry conditions, only requiring an occasional long soak during extended periods of heat.

No pruning is generally needed but removing flower stems after the main display to tidy the plant encourages further blooms. To stimulate vigorous growth, simply apply some slow-release fertiliser in spring.

 Ideal plant partners include other dry tolerant perennials such as Arthropodium ‘TePuna’ and Euphorbia ‘Cragieburn’.

 

Top gardening tips for December

• Give yourself and your garden a special treat. Add some interesting plants or accessories - a statue or a large, stylish container can make an interesting focal point.

• Pot up some herbs for some last minute gift ideas. Parsley, sage, rosemary and thyme are not only fragrant in the garden but have culinary uses as well.  
• Hang some fairy lights in the trees near your entertaining area.They create a touch of fantasy at Christmas time.  

• Brighten up the entrance to your home and entertaining area with some “instant colour” from your favourite garden centre. Select pots of petunias, salvias, alyssum or marigolds for sunny spots, and impatiens, begonias and coleus for the shade.
