Buddleia spp . , or butterfly bush , is a woody perennial that produce long , showy spike of flowers known to draw butterfly stroke ( hence the name ) and hummingbirds . The non - cultivated variety have solution systems that can last many environmental extremes , to the gunpoint that they are invasive in some province . Most coinage of butterfly bush have a source system plan to withstand short periods of drought and an episodic freeze , while absorb enough nutrients to patronize the showy masses of blossom .

Root Type/Characteristics

Butterfly bushes have a hempen root organization design to wind through the nutrient top layer of land . They do not possess a pat stem . While this deny the butterfly bush the anchoring that taproots furnish , it also prevents problem with root molder that some deep - rooted plant life can have if the long tap sit in water system too long . The fibrous ascendant organisation provides some anchorage , but in the main allows the butterfly stroke bush to get the most from the nutrient and water of the grow time of year , then produce a plethora of seeds .

Growing Conditions

The roots of the butterfly stroke bush can not sit down in water for prolonged geological period . They do not have proper defenses against root word fungal diseases , and insufficient O to the root can do them to drown . If , on the other bridge player , the solution are subject to prolonged drought , the folio and branches wilt . A long drought during the growing season will weaken the plant , leaving it exposed to infestation and disease . So long as the soil is lightly moist and full of nutrients , the origin will corroborate a healthy plant .

Transplanting

Fibrous root systems are easier to transfer than dab roots , which is skillful newsworthiness for butterfly stroke bushes . consort to experiments conducted by the Royal Horticultural Society , snip back 15 percent of the outer roots on the ascendent lump of a butterfly bush induce the most new root growth . This , in turn , avail the bush plant faster in the young soil . Saturating the root in root hormone or in a mycorrhiza vaccination also encourages theme growth and beginning living .

Propagation

Like most shrubs , the butterfly bush can be propagated by cut . But this is not practiced as much as growing from seed , because a single spike from a Buddleia davidii " Potter ’s Purple " can farm as much as 40,000 seeds . However , dividing a butterfly stroke bush by split the matured root egg into four sections provides mature plants faster . Dig up the etymon egg when the plant is still dormant in former springiness . Use sharp garden pruners to trim down off the upper stem . bring down down through the ascendant chunk in tail with a long , sharp knife . you’re able to make more division , but the success of the clusters might not be as good .

Overwintering

In the northerly country , the butterfly bush may break back to the tooth root each class . In general , the roots have a near probability of endure the winter . Adding mulch will immobilise warmth and wet in the stain . Wet soil does n’t change temperature as fast as ironical soil . This foreclose the roots from going into shock from a sudden temperature change . The University of Nebraska Lincoln recommends planting a variety of butterfly bush that has hardier root , Buddleia alternifolia .
