Paulownia (after Anna Paulowna, princess of the Netherlands).
 +
Scrophulariaceae. Ornamental trees, grown for their beautiful flowers
 +
in showy panicles and for their large handsome foliage.
  
−
'''''Paulownia''''' is a genus of between 6-17 species (depending on taxonomic authority) of [[plant]]s in the monogeneric family Paulowniaceae.
+
Deciduous, rarely half-evergreen: lvs. opposite, long- petioled,
 +
entire or sometimes 3-lobed or coarsely toothed, without stipules:
 +
fls.-. in terminal panicles; calyx campanulate, 5-lobed; corolla with
 +
long slightly curved tube, and spreading oblique 5-lobed limb;
 +
stamens 4: fr. a 2-celled caps., loculicidally dehiscent, with
 +
numerous small winged seeds.—About 8 species in China; in Japan only
 +
cult.
 +
 
 +
The paulownias are medium-sized or fairly large trees with stout
 +
spreading branches, large long-petioled leaves similar to those of
 +
catalpa, and violet or nearly white large flowers resembling those of
 +
the foxglove or gloxinia in shape, appearing in terminal panicles
 +
before or with the leaves and followed by ovoid pods remaining on the
 +
tree and conspicuous during the winter. P. tomentosa is fairly hardy
 +
in sheltered positions as far north as Massachusetts, but the
 +
flower-buds are usually - killed in winter, and it does not flower
 +
regularly north of New York City; plants raised from seed collected
 +
in Korea have proved hardier at the Arnold Arboretum than the
 +
commonly cultivated Japanese plant, also the var. lanata from Central
 +
China seems to be somewhat hardier. As an ornamental foliage plant it
 +
may be grown as far north as Montreal, where it is killed to the
 +
ground every winter, but throws up from the root vigorous shoots
 +
attaining 10 to 14 feet, with leaves over 1 foot and occasionally
 +
even 2 feet long. If used as a foliage plant and cut back to the
 +
ground every spring, the young shoots should be removed, except one
 +
or very few on each plant; during the first years of this treatment
 +
they will grow more vigorous every year, but afterward they will
 +
decrease in size, weakened by the continuous cutting back; they
 +
should then be replaced by strong young plants. Where the flower-buds
 +
which are formed the previous year are not killed by frost, the
 +
paulownia is one of the most conspicuous flowering trees in spring,
 +
and in summer the foliage, although it is of somewhat dull color,
 +
attracts attention by the size of the leaves. In temperate climates
 +
it is sometimes used as an avenue tree. It thrives best in a light
 +
deep loam, and in a sheltered position. The other species are still
 +
little known in cultivation and are probably tenderer; they are great
 +
favorites with the Chinese and much planted in central and southern
 +
China. Propagation is by seeds sown in spring or by root-cuttings,
 +
and by greenwood cuttings under glass; it may be grown also from
 +
leaf-cuttings; the young unfolding leaves when about 1 inch long are
 +
cut off close to the stems and inserted in sand under a hand-glass in
 +
the propagating-house.
 +
 
 +
Paulownia tomentosa in southern California reaches a height of 40
 +
feet in twenty-five years, with a spread nearly as great. When in
 +
full leaf it makes a dense shade. It starts to bloom before the
 +
leaves come and all is over before the tree is in full leaf. For this
 +
reason it is not a favorite. The Jacaranda is a prettier blue, more
 +
floriferous, lasts three times as long, the blooms continuing until
 +
the tree is in full leaf. It is out of leaf not more than half as
 +
long as is paulownia and in mild winters holds much of its foliage
 +
throughout, being properly an evergreen. It makes as dense shade as
 +
the paulownia, has a prettier leaf and is more desirable in every
 +
way. The growth of the two trees is about the same at the end of a
 +
quarter century. The habit of the paulownia in retaining dry
 +
seed-pods on dead limbs 3 or 4 feet long is very unpleasing, and
 +
necessitates a thorough cleaning each year to the tip end of the
 +
uppermost branch—often a hard task to accomplish. (Ernest Braunton.)
 +
P. Duclouxii, Dode. Tree, to 60 ft.: lvs. oblong-ovate, with open
 +

Paulownia (after Anna Paulowna, princess of the Netherlands). Scrophulariaceae. Ornamental trees, grown for their beautiful flowers in showy panicles and for their large handsome foliage.

Deciduous, rarely half-evergreen: lvs. opposite, long- petioled, entire or sometimes 3-lobed or coarsely toothed, without stipules: fls.-. in terminal panicles; calyx campanulate, 5-lobed; corolla with long slightly curved tube, and spreading oblique 5-lobed limb; stamens 4: fr. a 2-celled caps., loculicidally dehiscent, with numerous small winged seeds.—About 8 species in China; in Japan only cult.

The paulownias are medium-sized or fairly large trees with stout spreading branches, large long-petioled leaves similar to those of catalpa, and violet or nearly white large flowers resembling those of the foxglove or gloxinia in shape, appearing in terminal panicles before or with the leaves and followed by ovoid pods remaining on the tree and conspicuous during the winter. P. tomentosa is fairly hardy in sheltered positions as far north as Massachusetts, but the flower-buds are usually - killed in winter, and it does not flower regularly north of New York City; plants raised from seed collected in Korea have proved hardier at the Arnold Arboretum than the commonly cultivated Japanese plant, also the var. lanata from Central China seems to be somewhat hardier. As an ornamental foliage plant it may be grown as far north as Montreal, where it is killed to the ground every winter, but throws up from the root vigorous shoots attaining 10 to 14 feet, with leaves over 1 foot and occasionally even 2 feet long. If used as a foliage plant and cut back to the ground every spring, the young shoots should be removed, except one or very few on each plant; during the first years of this treatment they will grow more vigorous every year, but afterward they will decrease in size, weakened by the continuous cutting back; they should then be replaced by strong young plants.
