UNITED STATES—Spring bulbs, with prechilling, were conducive to the technique of forcing bloom earlier. A few summer bulbs might still be responsive to it, although it is getting late for most. Now, it is about time for forcing bloom with certain dormant deciduous stems. Most are already beginning to bloom. Forcing bloom merely accelerates this process for cut flower stems.
Forcing bloom for dormant deciduous stems is actually simpler than for bulbs. It involves merely cutting stems that are about to bloom and bringing them indoors. The warmth of a home interior is what accelerates profuse bloom. Aridity of home interiors may accelerate the deterioration of this bloom. However, homes also provide shelter from wind and rain.
Witch hazel, flowering quince and forsythia are mostly done blooming locally. Otherwise, they are conducive to forcing bloom, and will be available next winter. Several flowering cherries and flowering plums are now about ready for forcing bloom. Redbuds are ready also, though some will be later. Flowering crabapples should bloom later in their season.
Fruiting cherries are not too different from flowering cherries.
Several fruit trees are as conducive to forcing bloom as their fruitless flowering relatives. Their floral color and profusion are less extravagant only because of their breeding. Fruit is, after all, the priority. With planning, dormant pruning can involve leaving a few surplus stems to cut later. Then, cutting them about now should not compromise fruit production.
With precise timing, wisteria and lilac are conducive to forcing bloom. Technically, so are dogwood and several deciduous magnolias. They bloom relatively slowly though. A few flowers should therefore be blooming before collection of their stems. Evergreen species are less striking in bloom. Fringe flower and Oregon grape can perform elegantly though.
Forcing bloom is more popular where winters are cooler. This is partly because gardens lack floral color for so long through winter. Those who enjoy flowers are in more of a rush to bring some into their homes. Also, dormant vegetation is more reactive to warmth after colder winters. Warmth might not stimulate bloom as effectively after locally mild winters.
Highlight: Chinese Fringe Flower
The simple species is notably distinct from its several popular modern cultivars. Chinese fringe flower, Loropetalum chinense, grows very slowly to about fifteen feet tall. Its simple evergreen foliage is exclusively light green. Its small and ribbony flowers are exclusively creamy white. Limber and arching stems can eventually overwhelm adjacent vegetation.
However, this simple species is now very rare. Popular modern cultivars are much more compact. Although a few can grow taller, most are no more than five feet tall. Most exhibit delightfully purplish or bronzed foliage. Individual leaves grow about an inch or two long. Floral color ranges through white, creamy white, pink, rosy pink, rich red and garnet red.
Chinese fringe flower has a woodsy style. Shearing or aggressive pruning compromises its naturally relaxed form. It is naturally an understory species, so is somewhat tolerant of partial shade. Bloom is most abundant as winter relinquishes to early spring. It continues sporadically throughout most of the year. Blooming stems can be handsome cut flowers, and tolerate forcing bloom.
