Scientific name: Phlox drummondii
Common names: Phlox flower, blessing flower, colored plum, grass oleander, Campanulaceae, plum blossoms, small flowers, and small sky blue hydrangea.
Family: Polemoniaceae (Phlox family), commonly known as the "flower tolerance" section.
Origin: Native to North America, this plant is now widely cultivated across the globe.
Name origin: The genus name "Phlox" comes from the Greek word for "flame," as the original species of this flower was red in color. It was named after the Scottish botanist Thomas Drummond.
Morphological characteristics:
This herbaceous perennial grows between 15 to 45 cm tall. The stems are erect, highly branched, and covered with glandular hairs. Leaves are alternate, with basal leaves opposite, broadly ovate, oblong, or acicular in shape, ranging from 2 to 7.5 cm in length. The leaf tips are acute or cuspidate, and the base is tapered or slightly stalk-like. The leaves are hairy on top and have only glandular hairs underneath. They are sessile, with terminal cymes that are pubescent. Bracts and bracteoles are present. The calyx tube is striped, and the outer surface is hairy. The corolla is salverform, with a diameter of 2 to 2.5 cm, and the lobes are rounded. The stamens do not extend beyond the corolla. The original flower color is rose red, and it blooms from May to June. The fruit is an oval capsule with persistent sepals. The seeds are oblong, with a raised back and flat ventral surface. Seed viability can last up to two years, with 1,000 seeds weighing approximately 1.55 grams.
In horticulture, there are many varieties based on color and petal type:
Single-color varieties include white, yellow, various shades of red and purple, as well as light and deep purple.
Two-color varieties feature different colors on the inside and outside of the flower, or have two tones on the crown, with spots in the throat, stripes on the petals, or a white pentagonal star in the center.
Three-color varieties may have combinations like rose with a white base, a yellow heart with white, or a blue and white center. Based on petal types, there are round-petaled, star-petaled, shrub-type, and radiated varieties, as well as high and low-growing types.
Varieties of Phlox:
'Palona' is a dwarf variety suitable for small pots. It has a compact shape, strong branching, and is ideal for container planting or flower beds.
Variants:
var. rotundata – round-petaled, with large, wide, and round petals.
var. stellaris – star-petaled, with tridentate edges and long teeth.
var. fibriata – with finely divided edges on the corolla lobes.
var. radiata – with lanceolate, elongated corolla lobes.
This plant prefers cool to warm temperatures and is sensitive to excessive heat. In northern China, cold frames can be used for winter protection. It thrives in well-drained, loose loamy soil and is drought-tolerant.
Propagation is typically done through sowing. Autumn sowing is recommended, as well as spring sowing in colder regions. Germination occurs best at 15–20°C.
Seeds maintain viability for 1–2 years. For autumn-sown plants, seedlings should be transplanted in late October to cold beds for winter survival, then moved to open ground in early spring. Fertilize regularly and transplant to garden beds in mid-April.
This plant has a long flowering period, and pods mature at different times. To prevent seed loss, cut the inflorescences when most pods are yellow and dry, then thresh them.
Uses:
Phlox is a low-growing, colorful plant, ideal for flower beds, gardens, rockeries, and potted indoor decoration. Taller varieties can be used as cut flowers. It also has good resistance to sulfur dioxide and some tolerance to chlorine.
