Scientific Name Mimosa borealis A. Gray [图片]Common Names Fragrant Mimosa, Pink Mimosa, Catclaw Mimosa, Sensitive Mimosa Synonyms Mimosa fragrans Scientific Classification Family: Fabaceae Subfamily: Mimosoideae Tribe: Mimoseae Genus: Mimosa [图片]Flower Color: Pink Bloom Time: Spring through summer Description Mimosa borealis is a deciduous, small shrub, up to 3 feet (90 cm) tall and wide, with slightly zigzag, rigid branches with small, delicate pinnately compound leaves. The fragrant, showy, pink globe flowers with yellow anthers. Blooms in spring and then intermittently all through the summer. [图片]How to Grow and Care Mimosa is capable of growing in some really hardy zones and can survive in temperatures as low as -10 degrees Fahrenheit (-23 degrees Celsius). Although it grows exceptionally well in bright and full sunlight, it can grow in partially shaded areas as well. The plant can grow on a large variety of soil types like clay, loam, and sandy soil. The soil should ideally be acidic but a mild alkaline soil would suffice too. The plant is known to survive in droughts and hence requires little watering. The ideal time for planting a Mimosa is during the spring on a well drained soil. As these flowering plants prefer soil which is acidic in nature, it is advised that you add peat moss and composted leaves at regular intervals to maintain its acidic properties. Water the plant and soil enough, but not so much as to saturate it. Keep the area under the tree clean, by sweeping away the fallen flowers and seed pods. Pruning of the branches should ideally be done during fall. This tree often tends to get infested by pests like webworm caterpillars. If affected, the branches should be removed as soon as possible to prevent any collateral damage to the plant. If not taken care of, the need to spray insecticides might arise. Origin Native to Kansas and southeastern Colorado south to northern Mexico.

Cuttings of Mint will root easily in soil or water and mature plants can be divided and transplanted. However you can start new plants from seed. Sow outdoors in late spring or start seed indoors about 8 to 10 weeks before the last frost. Keep soil moist until seed germinates. Mint prefers a rich, moist soil with a slightly acidic pH between 6.5 and 7.0. If the soil is somewhat lean, top dress yearly with organic matter and apply an organic fertilizer mid-season, after shearing. To contain the roots and limit spreading, you can grow Mint in containers, above or sunk into the ground. Be careful to keep container Mints from flopping over and touching the ground. Stems will root quickly, if given the chance. Origin Garden origin.

Scientific Name Meconopsis horridula Hook. f. & Thomson [图片]Common Names Prickly Blue Poppy, Tibetan Poppy Scientific Classification Family: Papaveraceae Subfamily: Papaveroideae Tribe: Papavereae Genus: Meconopsis [图片]Flower Color: Blue or reddish blue Bloom Time: Late spring to early summer Description Meconopsis horridula is a flowering plant with basal leaves, up to 10 inches (25 cm) long, arranged in a rosette. The stem and pedicels have straw-colored spines on their surface. The leaves are elliptical or narrow-oblong shaped, tapering into the petiole. The leaf margin is entire or slightly lobed or toothed. The surface of the leaf is covered with yellowish or purplish spines that grow from purple wart-like structures. In some cases they are covered with bristles. The upper leaves are smaller and bract-like. The open-faced flowers are usually in shades of blue or reddish blue, but rarely white. The flowers are up to 3 inches (7.5 cm) in size. The stalk is up to 9 inches (22.5 cm) long. The stalk that bears the flower is bent, so the flower is not held upright and is droopy. [图片]How to Grow and Care Full sunlight (cool areas only); full or partial shade. Acidic soil. Add grit to heavy soils. Nutrient-rich soil, add manure, leaf matter or compost if necessary. Moist soil. Supply mulch of manure of bark chippings when planting to help maintain moisture; do not cover the crowns. Regular watering during dry periods in summer to keep the soil moist. No need to water in the winter as the plant prefers a dry soil whilst resting. Cut back to the ground in autumn. Replace regularly as Meconopsis do not live for long time. When growing Meconopsis plants in the garden it is very important to keep the soil moist in the summer. Once the growing period has finished, cut back Meconopsis plant to ground level (autumn). If you require more plants then they can be propagated by division at the start of spring. The seeds of the Meconopsis should be sown on the surface; this can wither be done just before the last frost of spring or towards the end of autumn. Blue Poppies prefer to grow in a shady or partially shady part of the gardens but can tolerate sunny areas in milder climates. They like a rich acidic soil, ideally the soil should be kept moist in the summer, but allowed to dry in the winter. Origin Native to China (Tibet).

The soil should be dry. Once your Chamomile is established, it needs very little care. Like most herbs, it grows best when it is not fussed over. Too much fertilizer will result in lots of weakly flavored foliage and few flowers. Chamomile is drought tolerant and only needs to be watered in times of prolonged drought. Plant Chamomile in the spring from either seeds or plants. It’s easier to establish Chamomile herb in your garden from plants or divisions than from seeds, but growing Chamomile from seed is also relatively easy.
