Pickerelweed typically grows to about 2 to 3 Ft tall. Pickerelweed is an aquatic or marsh perennial with a cluster of erect arrowhead-shaped leaves arising from a single basal clump. Its leaves are large, up to 5" wide, and are usually twice as long. Leaf shapes are variable, but are usually lance-shaped. The easiest way to recognize pickerelweed is by its spike of violet-blue flowers. Sometimes the flowers are white. Plant pickerelweed in the margins of a garden pond or water garden. You can plant it in a pot, then set the pot in the water. That way you can change the depth and position of the plant if necessary. Cut flowers are strikingly beautiful when viewed up close, and although each individual flower lasts only one day, more will open each day and the entire inflorescence will last for several days in a vase of water. Propagation: The rootstock of large plants is easily divided.

Porphyrocoma pohliana is a tropical evergreen plant that is a prolific bloomer in the tropics. This plant is adaptable, beautiful and flowers all year round in low light. Great as a container and indoor plant. Rose-colored cones emerge on the growing tips and expand until brilliant purple flowers appear among the colorful bracts. The dark green leaves are accented by silver highlights. It should be grown in a fertile, well draining soil mix that is rich in organic matter. Like many shrubs, it is necessary to prune Porphyrocoma pohliana regularly to ensure that it retains a compact growth habit. Outdoors, this plant can be grown in the shade, but not in full or direct sunlight. Strong sunshine can bleach the leaves.

Primula x polyantha

Primula sp.

Primrose
Family: Primulaceae
Origin: China
USDA Zone: 4-10?
USDA Plant Hardiness MapSmall plant 2-5 ftSemi-shadeRegular waterPink flowersWhite, off-white flowersBlue, lavender, purple flowersRed, crimson, vinous flowersYellow, orange flowersAttracts butterflies, hummingbirdsSubtropical, mature plant cold hardy at least to 30s F for a short time

Primrose (Primula sp.) is an attractive small shrub growing 2-5 feet tall with mounds of colorful blooms, often fragrant, in shades of pink, white, off-white, blue, lavender, purple, red, crimson, vinous and yellow and orange colors. It is a perennial, native to China and is low maintenance plant with easy to propagate features. It is attractive to butterflies and hummingbirds and will bring a little bit of extra color to any garden.

In USDA Plant Hardiness Zones 9-11, primrose blooms in spring and may re-bloom in autumn. Its flowers may last for up to four weeks. In cold regions, however, primrose can survive in containers, provided the plant is mulched heavily and moved to a sheltered spot during cold winter months.

Primrose prefers semi-shade and regular water, especially during flowering and in dry weather. Even though it`s a hardy species, it needs well-draining soil and regular feeding, especially during the growing season. Planting in raised beds or planters is a good idea, as it allows for proper water drainage. To keep the flowers blooming, deadheading is also recommended, but only once the flowers have fully faded.

When temperatures dip below freezing, the primrose should be covered with mulch to protect its roots from the cold.

Primrose is an eye-catching plant and its vibrant flowers make it a perfect addition to any garden. With its easy-to-care features, this perennial makes an ideal long-term companion, bringing joy to your outdoor space year after year.
