'Sunshine Daydream' Helianthus for Mid-Summer Bloom

Sunshine Daydream (Helianthus x multiflorus ‘Sunshine Daydream’) has been blooming non-stop in my Northeast Tennessee garden for the past two months.

This double-flowering yellow false sunflower is a new introduction from North Creek Nurseries, a wholesale nursery in Landenberg, PA. Sunshine Daydream is a branch sport (mutation) of native cultivar ‘Capenoch Star’. It is a mid-summer flowering perennial.

Sturdy 5 - 6 feet tall by 2 - 4 feet wide plants support bouquets of bright yellow double flowers. The dahlia-like blooms measure 2.5 inches across. The spent flowers are seedless and do not threaten to become a weedy problem in years to come.

Sunshine Daydream performs best in full sun, preferably in moist well-drained soil. Keep plants in full vigor with monthly applications of a water-soluble fertilizer such as Miracle -Gro™ or equivalent or feed bi-monthly with 10-10-10 or equivalent.

Sunshine Daydream stands up to summer's heat and humidity. Established 1- year old plants are moderately drought tolerant. This long-lived perennial is hardy in USDA zones 4 thru 8. The summer foliage of Sunshine Daydream is remarkably resistant to powdery mildew, a fungal disease which plagues some helianthus species.

Cardinal Flower – A Hummingbird Magnet

Cardinal flower (Lobelia cardinalis) is a hardy perennial native in USDA zones 5-8. Clumps should be divided every 2-3 years to retain plant vigor. Soil moisture determines its height and vigor.

Cardinal flower prefers half-day direct morning sunlight, particularly in more southern climes. The brilliant red flowers bloom from late July through most of September, making it a standout on their own or mixed with other perennials. Deadheading (pruning off the old floral stems) extends out its flowering period.

Cardinal flower grows 3 feet high and 2 ½ feet wide, and is taller when planted at the edge of a pond or water garden. This lobelia is at home in a rain garden, particularly when summer moisture is plentiful. Fertilize with a water soluble product monthly or feed bi-monthly with agricultural grade fertilizer (10-10-10 or equivalent) from late winter to the end of the flowering period.

Select these two cultivars -- ‘Fried Green Tomatoes’ exhibits bright green foliage which turns a deep olive color on the leaf upper surface and maroon on the underside; flowers are bright red. ‘Monet Moment’ bears exquisite rose-pink flowers. Blooms on both cultivars are exceptionally larger than species.

'Buttered Popcorn' Daylily- Performs In The Mid-South

Daylily 'Buttered Popcorn' (Hemerocallis 'Buttered Popcorn') produces buttery yellow 6" flowers from late June thru mid-July. The 32-inch tall floral scapes are well branched and flowers are mildly fragrant. Bud count on each scape may average 10 or more.

This tetraploid cultivar is also well known for its incredible fall re-bloom. In the Southern Appalachian Region (zones 6-7), 'Buttered Popcorn' is rated as a better re-blooming daylily than popular favorite 'Stella de Oro'.

Daylilies require little care. They grow in almost any well-drained soil type. Daylilies grow best in full to partially sunny areas. Allow 6 hours of sunlight for high bud bloom count. Although drought tolerant, re-blooming varieties perform best with 1-inch or more of water (or rainfall) per week during the summer months.

In late fall, cutback daylilies to 3-6 inches in height. Remove the old plant debris. Daylilies possess good disease and pest resistance. Fertilize once with 10-10-10 and mulch plants in late winter or spring. Feed a second time in early June before flowering begins.

Daylilies are great additions to large containers or plant them in garden beds. The short (under 24-inch tall) daylily varieties are also utilized as ground covers along steep slopes.
