Butterfly Bush

Buddleias require full sun on fertile, well drained soil.
The Butterfly Bush is moderately tolerant of drought and very tolerant of chalky soil. Insect pest and disease problems are rare, spider mites may occur on hot dry sites. Propagation is easy from half hardened cuttings taken in summer. The species can be easily grown from seed.

Buiddleia albiflora
A vigorous, deciduous shrub, reaching a maximum height of 13 feet, that is native to China.
The toothed, pointed, lance-shaped, ovate or narrow-elliptic leaves, up to 12 x 4 inches, are downy beneath.
The fragrant, pale-lilac flowers are borne on narrow panicles, up to 20 x 2 inches, during summer.
The stems are rounded rather than angled.
Hardy zones 6 to 9.

Buddleia alternifolia ( Fountain Buddleia )
A very fine, very fast growing, dense, deciduous shrub or small tree that is native to northwest China. The Fountain Buddleia can reach 3 feet in the first year and eventually around 15 feet or sometimes much larger. The largest on record is 33 x 33 feet.
The alternate spaced leaves are deep gray-green above, whitish below and up to 4 x 0.5 inches.
The very fragrant, mauve-pink flowers, up to 1 inch across, are borne in tight clusters up and down the entire length of the long, arching and weeping stems. They are borne during late spring to early summer.
The flowers are excellent for attracting hummingbirds and butterflies. This species can be mixed with Buddleia davidii resulting in Butterfly attraction from spring through fall.
Hardy zones 4 to 9 in full sun to partial shade on just about any well drained soil including clay and limestone. It is among the hardiest of Buddleia, thriving even in the Ottawa Valley. Deer resistant. Unlike Buddleia davidii; this species should NOT be cut back in early spring. The only pruning on this one is deadheading old bloom stems after flowering to encourage vigor. This species is not grown as a perennial, it is 100% shrub/tree. It is sometimes trained as a very attractive, small weeping tree.
Propagation is from semi-ripe cuttings taken during summer.

Hardier than regular B. colvillei, to zone 7.

Buddleia cordata ( Mexican Butterflybush )

The foliage is gray-green above, paler beneath.
The creamy-white to deep orange flowers are borne during winter.
Hardy zones 7 to 11 ( minor foliage damage occurs at 25 F ) in full sun on well drained soil. It very drought tolerant but is not flood tolerant.

Buddleia crispa
A bushy, upright, deciduous, large shrub that is native to hillsides in the Himalayas, Afghanistan and western China. Some records include: 10 years - 10 x 10 feet; largest on record - 20 x 20 feet. Slower growing than most species, it typically reaches only 2 x 3 feet in the second year. If grown as a perennial north of zone 7, it typically reaches up to 3 feet.
The toothed, oval leaves, up to 8 x 3 ( rarely over 5 x 2 ) inches, are silvery-gray to deep gray-green and felted.
The very fragrant, small, lilac ( with white to orange throat ) flowers are borne on dense whorled panicles, up to 4.8 ( rarely 8 ) inches in length, during mid to late summer ( then sporadically until autumn frost ). The flowers are very attractive to butterflies. It blooms on new woods and therefore will bloom if the stems freeze back during winter.
The young stems are woolly white.
Hardy zones 7 to 9 ( reported to thrive in zone 4b in Ottawa, Ontario as a perennial ) in full sun on very well drained soil. It is very tolerant of and actually prefers alkaline soils.
In cooler areas it is best planted against a warm south facing wall. For best appearance, cut back hard or even to the ground during late winter.
Propagation is from seed or semi-ripe cuttings taken during summer.

'Agathosma'
Very striking, very large foliage that is white beneath.

Budddleia curviflora
Also called Buddleia venenifera. A deciduous, medium-sized shrub, reaching up to 6.5 feet, that is native to southern Japan and Taiwan.
The narrowly-ovate to elliptical leaves, up to 6.3 x 2.8 inches in size, are bright green to gray-green above, silvery-white beneath.
The purple flowers are borne on narrow clusters, up to 8 x 1.6 inches in size, during early to mid-summer.
Hardy zones 8 to 9.

Buddleia davidii ( Butterfly Bush )
A very fast growing hardy, deciduous ( semi-evergreen in very mild climates ), arching shrub native to central and western China. Butterfly Bushes not pruned back, generally become large shrub south of zone 6; up to 10 feet is common and the largest on record is 23 x 20 feet. Grown as a cutback shrub, they often reach up to 8 feet by the end of summer.
The pointed, lance shape to ovate, pointed leaves are up to 12 x 4 inches in size. The foliage is deep sage green above and woolly white beneath.
The typically sweetly fragrant flowers are borne in long panicles beginning in mid summer and lasting until autumn frost. Many cultivars have been developed as the Butterfly Bush is variable in color, the species is most often lilac-pink to purple in color.
Among the most popular plants for encouraging Butterflies and Hummingbirds. While I see many plants that are popular for "just because"; this plants reputation is well deserved and many of its cultivars when well grown are "just plain awesome".
Plants cut back hard to 6 inches from ground level in March grow the most vigorously and flower the best, though I've seen many very attractive plants that are only occasionally tip pruned to encourage density and longer bloom season. Old flower spikes should be removed in summer to encourage new flower spikes to form.
Hardy zones 6 to 9 ( zone 5 as a perennial ) in full sun on fertile, well drained soil. Tolerant of limestone soils, pollution and seashore conditions. Thorough fertilization with a 10-10-10 or 15-15-15 ( especially if time release ) is recommended. Mulch deeply during winter to protect roots from extreme winter cold north of zone 7.
The Butterfly Bush is very heat tolerant, moderately drought tolerant and very tolerant of chalky soil. Not generally bothered by pests or disease, these Buddleias are among the best of all plants for attracting butterflies and hummingbirds. Propagation is easy from half hardened cuttings taken in summer or hardwood cuttings taken during autumn. Buddleias davidii can be a prolific seed producer and seedlings can be variable. In some areas it may be invasive, in such areas only non-seeding cultivars and hybrids should be used.
