Dianthus x allwoodii 'Frosty Fire'

Overall Description

Frosty Fire Dianthus is a low growing flowering perennial that was formed by English Nurseryman Montague Allwood by crossing two different types of Dianthus ( D. plumarius and D. caryophylus ). Quite hardy & adaptable to many climates & conditions, making it an excellent border plant, groundcover, or rock & container gardening selection. Foliage is somewhat grasslike, and forms vigorous clumplike mats of bluish grey. Typical bloom time is early May through the end of June....mostly depending on just what hardiness zone you are planting in. Bloom color is a vibrant red with very small sporadic spots of white in some flowers. Bloom time can be extended quite some time through the removal of older, expired flower heads - which also helps to give the mound a nice neatly trimmed shape. Frosty Fire is known to rebloom again in fall, especially if older expired flower heads are removed.

Accepts full sun locations, but can also benefit from an occasional break from hot afternoon sun. A wonderful perennial with a multitude of beneficial uses in landscapes, and with low maintenance, hardiness, and pest resistance. Perfect combination!

----Recommended Spacing :
18" - 20" apart recommended for accent or border plantings - 12" - 16" apart for mass planting, or groundcover applications where a distinct break between individual plants is not desired.

--Deer Resistance Rating :
Lowest Resistance [ 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 - 10 ] Highest Resistance

--Fertilization / Feeding :
For maximum health & hardiness, we highly recommend a good grade granular ( preferably organic ) fertilizer / plant food for use with all of our plant species. We personally use, and recommend the Espoma line of organic plant foods, as they are super effective yet gentle enough to use on even the most delicate of evergreen species where fertilizer burn would normally be a major concern. However, a water soluble type plant food (Miracle Gro, or equivalent ) are also acceptable options. Other granular fertilizers with a 6 - 12 - 12, or 10 - 10 - 10 ratio can also be used - but we suggest using them at 1/2 - 3/4 strength to avoid any chemical burn issues to the root system of the plants. Best to fertilize in early spring, and again in mid fall - avoid feeding standard chemical fertilizers during hot summer months, and directly after transplanting. The Espoma Organic Plant Foods may be used at anytime.
