Daliah

Dahlia is a genus of bushy, tuberous, herbaceous perennial plants native to Mexico, Central America, and Colombia. A member of the Asteraceae or Compositae, dicotyledonous plants, related species include the sunflower, daisy, chrysanthemum and zinnia. There are at least 36 species of dahlia, with hybrids commonly grown as garden plants. Flower forms are variable, with one head per stem; these can be as small as 2 in (5.1 cm) in diameter or up to 1 ft (30 cm) ("dinner plate"). This great variety results from dahlias being octoploids—that is, they have eight sets of homologous chromosomes, whereas most plants have only two. In addition, dahlias also contain many transposons - genetic pieces that move from place to place upon an allele - which contributes to their manifesting such great diversity.Dahlias grow naturally in climates which do not experience frost (the tubers are hardy to USDA Zone 8),^[34] consequently they are not adapted to withstand sub-zero temperatures. However their tuberous nature enables them to survive periods of dormancy, and this characteristic means that gardeners in temperate climates with frosts can grow dahlias successfully, provided the tubers are lifted from the ground and stored in cool yet frost-free conditions during the winter. Planting the tubers quite deep (10 – 15 cm) also provides some protection. When in active growth, modern dahlia hybrids perform most successfully in well-watered yet free-draining soils, in situations receiving plenty of sunlight. Taller cultivars usually require some form of staking as they grow, and all garden dahlias need deadheading regularly, once flowering commences.

Red/Yellow Daylily

The daylily is often called "the perfect perennial," due to its dazzling colors, ability to tolerate drought, capability to thrive in many zones, and requiring very little care. Daylilies thrive in full sun, although certain daylilies require partial shade, depending on color. Lighter shades, such as yellow, pink, and pastels require the sun to bring out all of their color. Darker daylilies, such as some red and purple flowers, need shade because their darker colors absorb heat.  Today, daylilies come in an assortment of shades, whereas they formerly were only available in yellow, pink, fulvous, and rosy-fulvous. Now the flowers can be found in many shades of yellow, pink, red, purple, and melon. The only shades daylilies are not available in are pure blue and pure white, which hybridizers are working on.  Daylilies have a relatively short blooming period, depending on the type of daylily. There are a variety of different daylilies; some of which will bloom in early spring, while other wait until the summer or even fall. Most daylilies bloom for one to five weeks, although there is a type of daylily known as a re-bloomer, which will bloom twice in one season.

Lavender Plant

Lavender plants will tolerate many growing conditions, but it thrives in warm, well-drained soil and full sun. Like many plants grown for their essential oils, a lean soil will encourage a higher concentration of oils. An alkaline and especially chalky soil will enhance lavenders fragrance. While you can grow lavender in USDA Zone 5, it is unlikely you will ever have a lavender hedge. More realistically you can expect to have plants that will do well when the weather cooperates and to experience the occasional loss of a plant or two after a severe winter or a wet, humid summer.  Lavender is a tough plant and is extremely drought resistant, once established. However, when first starting you lavender plants, don't be afraid to give them a handful of compost in the planting hole and to keep them regularly watered during their first growing season. It is dampness, more than cold, that is responsible for killing lavender plants. Dampness can come in the form of wet roots during the winter months or high humidity in the summer. If humidity is a problem, make sure you have plenty of space between your plants for air flow and always plant in a sunny location. Areas where the ground routinely freezes and thaws throughout the winter will benefit from a layer of mulch applied after the ground initially freezes. Also protect your lavender plants from harsh winter winds. Planting next to a stone or brick wall will provide additional heat and protection.

 



Lobelia Siphilitica

(blue cardinal flower, clump forming perennial, 2+’,

Money Plant

Money plants are pretty easy to look after; they will self seed so if you do not require money plants in the garden the following year, remove the plants before they shed seed. It is necessary to mulch the plants at the beginning of winter if you are planning to grow as a biennial.

 

 

 

Obedient Plant

Obedient plants are easily established and very drought tolerant, forgiving plants. Although they prefer a moist, slightly acidic soil (5.5 - 6.3 pH), they’ll grow just fine in average - poor soil and spreading will be less of a problem. The biggest maintenance chore is keeping obedient plant from rampant spreading. Although the plants pull out easily enough, they seem to pop up everywhere. If you’re tempted to wait and let them flower, be sure to get out there before they go to seed. Long season gardeners can get a second flush of blooms if you deadhead the first flowers. Wait until spring to cut back old foliage.
