ATTRACTIVE: Buddlejas are attractive for the gardener as well as butterflies and other insects.Buddlejas,those beautiful butterfly bushesso called because their nectar rich flower spikesattract butterflies to them, are probably the most amenable of all shrubs to soil type, acid or alkaline, but theydo prefer a well drained situation in the garden for the bestresults.They flower well in full sun and like shelter from strong winds as their wood is inclined to be brittle. These hardy plants arealsodrought and salt tolerant soaresuitable forcoastal gardens.
Named after the Reverend Adam Buddle, a botanist from Essexin England in the seventeenth century, buddlejas flower prolifically instunning colours of white, purple, pink, orange, yellow and magenta.Some are fragrant. They belong to the same family as foxgloves, Scrophulariaceae.
Buddlejas are big feeders and appreciate the addition of composted material used as amulch.Well suited to the open garden they are not good subjects for growing in containers due to their coarse root system.
Buddlejas benefit from deadheading as the blooms fade to encourage the production of subsidiary flower spikes to extend the flowering season.
Theyhave been known to naturalise in Tasmania in disturbed ground in urban areas especially along roadsides.The tiny, winged seeds spreadon the wind so its important to prevent them from becoming a potential problem by removing allspent flowers before they can seed.
Buddlejas are quick growing with a spreading habit andtherefore need to be prunedhardto control their size and to remove dead or weak growth. If you grow varieties that flower on the previous season’s wood, those that flower in late winter or spring, prune the flowering shoots back as soon as flowering stops.The new growth will mature to flower in the following winter.
Late summer flowering and autumn types should be pruned back in late winter.Old shrubs can be pruned back very hard to rejuvenate them, but feed well after any drastic pruning.
Buddleja davidii cultivars are suitable to use as centre pieces or asbackground plantsin the mixed shrub bedbecause of their flower size andabundance of blooms.
