The Heather is not difficult to
grow in the United States. It likes moisture at all times, but not at
all a wet soil, and it prefers partial shade from warm sunshine, and
shelter from sweeping winds. in the northern and mountainous parts of
the country it behaves very well; but it is a question if it can be
grown here with European luxuriance.
While not hardy in all situations, the plants do
fairly well in New England. At Forest Hill Cemetery, Mass., there is a
number of groups that receive no protection whatever. Around New York,
New Jersey and Philadelphia they should need no protection. They all do
well with a slight covering of leaves or meadow hay, and well repay the
trouble, as they bloom nearly all summer.
All ericaceous plants have fine, hair-like roots,
and, in common with all plants with roots of similar character, delight
in light soil. They are well suited in soil containing many small
stones, and of a sandy nature. The stones keep the soil open, which is
what the roots desire. Such roots are often poor. Because of this it is
inferred by many that the plants referred to do not care for better
soil; but this is a mistake. The roots are suited in such situations,
but the plants will show a marked improvement in growth if a mulching of
good soil be given them. It has been found that the Heather grows most
luxuriantly in a soil that contains a more than usual store of oxide of
Heather from seed requires as careful treatment as does the
multiplication of any of the plants belonging to the heath family, by a
similar method of propagation. The soil most suitable in which to sow
seeds of Scotch Heather is one composed of good peat loam and sharp,
clean sand, in equal parts. The soil should be made fine by passing it
through a small-meshed sieve. Shallow earthen pans, or shallow boxes,
are the most desirable receptacles for sowing the seed in, although
preference should be given to the earthen pans, as there is less danger
of fungous attacks by their use than in the case of the wooden boxes.
The pans should be well drained with broken crocks, and a layer of
sphagnum moss should be placed over the crocks, so as to prevent the
soil washing into the drainage. After the pans, or boxes, are thoroughly
drained, put into them two or three inches of the above compost,
pressing it down firmly and evenly. When this is done give the soil a
watering with a fine rose, and after the soil has absorbed all the water
the seeds may then be sown.
As the seeds are small, they have to be sown
carefully and evenly over the surface of the material used, and very
slightly covered with soil. The pans, or boxes, may now be placed in a
temperature ranging from So to 6o degrees, and they must be carefully
watched so that they may not get dry. When the seeds germinate, if there
is any sign of fungus, the young plants should at once be transplanted
into fresh soil, which is one of the best remedies to check damping off.
If the seeds are sown in January, or February, the young plants will
require to be transplanted several times during the first summer. This
tends to make them vigorous for the future; and during the first winter
it will be well to keep them in a cold frame. The following spring the
plants may be set out in their permanent positions.
The Calluna is easily propagated by cuttings,
under glass, during winter and spring, and by hillock layering; that is,
sifting in sandy loam among the branches and keeping same moist for two
or three months, when the plants so treated can be taken up and divided.
Make the cuttings, under glass, during the latter
half of September, earlier further north, of from two to three inches in
length, putting them in a mixture of sandy peat in a close, cool frame,
facing north. When rooted they can be placed close around the edge of a
six-inch pot, using moss, peat and loam, mixed. A temperature of 40 to
45 degrees is suitable in which to grow them, and great care should be
exercised as to watering, so as to avoid too much moisture at the roots.
There is a growing affection for the plant as a
garden subject in America; not long ago a landed proprietor in
Massachusetts expressed the desire to cover a hillside on his estate
with the Heather.
recent visit this year to Biltmore, N. C., the author observed numerous
plants of Heather, purple and white varieties, interspersed among the
vegetation bordering the driveways leading to Biltmore House, the
Southern home of Mr. George W. Vanderbilt. The plants appear to thrive
well, evidently finding congenial conditions in this lovely mountainous
district of the sunny Southland.
It may be well to state, however, that attempts
have been made to grow the Heather in gardens in several other parts of
the United States, with varying degrees of success. At Glen Cove, Long
Island, a variety of Calluna vulgaris (Alporti) succumbed to the hard
winter, the stems splitting just above the surface of the ground.
In the Botanic Garden at Washington, the
superintendent of which is a Scotsman, Mr. Wm. R. Smith, Heather has a
hard struggle for existence. There it is grown in a cold frame, in pots,
covered with a sash in winter, and with lath slats in summer. It has
been tried there in the open border and in the rock garden, but all to
no purpose. When a dry spell, with hot weather, came along, the plants
could not withstand these conditions, and so perished.
When the statue was erected to the poet Burns in
Washington Park, at Albany, N. Y., Mr. Peter Kinnear, a prominent Scotch
citizen there, procured some plants of Heather from Mr. Smith at
Washington to be placed around the base of the statue. The plants
arrived in the fall, were put in a cold frame, and the following spring,
as soon as the flower buds began to swell, were taken up and planted.
The statue faces south, is in the open, and receives the full strength
of the sun for the greater part of the day. The soil was specially
prepared for the plants, stiff, clayey loam being thrown out, good
drainage supplied, and friable, sandy loam, with some leaf mould, being
substituted. The plants bloomed well, made some growth in May and June,
and succumbed during the heat of July and August.
