Culture NotesHemerocallis hybrids come in a wide range of colors, flowering times and sizes, and some even come with a fragrance. For the most part, daylilies are long-lived, hardy perennials that are tolerant of the sun. However, some species will show sun scald and prefer partial sun. Daylilies are adaptable to a wide range of soil conditions, and most bloom from late June until the first frost (depending on the cultivar). These plants attract both butterflies and hummingbirds and, usually, are both heat and drought resistant. Hemerocallis are extremely tough plants that spread rapidly in most conditions, thereby choking out weeds without becoming invasive themselves. The best time to plant daylilies is early spring. Although the individual blooms are short-lived, the number of blooms you get from an average flower stalk continues on for weeks.

Daylilies adapt to almost any location that provides at least six hours of sunlight, but it's best to plant them in a prepared, raised bed of soil that is high in organic matter. For clay soil, coarse sand and organic matter should be mixed in. When planted, the crown should be even with the soil line. The growth rate of daylilies can be increased via generous irrigation practices. At the end of the flowering season, remove the spent flower stalks only so that the remaining dying foliage will protect the center of the plant through the colder winter months. Also, division of the plant every two or three years will increase stem strength and flower size.

'Black Eyed Stella' is an All American Daylily Selection. A heavy rebloomer, its ruffled flowers are golden yellow with a dark red eye.

EnvironmentThis plant tolerates drought.
This plant will grow in very dry soil.
Suitable soil is well-drained/loamy, sandy or clay.
The pH preference is an acidic to slightly alkaline (less than 6.8 to 7.7) soil.

Leaf Color Green
Fall Color No change in fall color

Culture NotesLilac is a common flowering shrub that grows best in a sunny location. The plant will grow in shade but flowering is poor and powdery mildew is likely to be severe. The growth rate is rapid and the plant produces many suckers. Pollen bothers certain people.

Planting and establishing shrubsThe most common cause of young plant failure is planting too deep. Plant the root ball no deeper than it was in the nursery. In most instances, the root flare zone (point where the top-most root in the root ball originates from the trunk) should be located just above the landscape soil surface. Sometimes plants come from the nursery with soil over the root flare. If there is soil over this area, scrape it off. The planting hole should be at least twice the width of the root ball, preferably wider. In all but exceptional circumstances where the soil is very poor, there is no need to incorporate anything into the backfill soil except the loosened soil that came out of the planting hole. Never place ANY soil over the root ball. If a row or grouping of plants is to be installed, excavating or loosening the soil in the entire bed and incorporating organic matter enhances root growth and establishment rate.

Weed suppression during establishment is essential. Apply a 3-inch thick layer of mulch around the plant to help control weed growth. Keep it at least 10 inches from the trunk. If you apply it over the root ball, apply only a one or two inch layer. This allows rainwater and air to easily enter the root ball and keeps the trunk dry. Placing mulch against the trunk or applying too thick a layer above the root ball can kill the plant by oxygen starvation, death of bark, stem and root diseases, prevention of hardening off for winter, vole and other rodent damage to the trunk, keeping soil too wet, or repelling water. Regular irrigation through the first growing season after planting encourages rapid root growth, which is essential for quick plant establishment.

Deciduous Shrub Of The Day

Hydrangea paniculata 'Pee Wee'
Panicle Hydrangea, Hybrid Hydrangea, PeeGee Hydrangea

Type Shrub, woody plant
Hardy range 3B to 8A
Height 6' to 15' / 1.80m to 4.60m
Spread 6' to 10' / 1.80m to 3.00m
Growth rate Average
Form Vase shaped
Exposure Partial shade or partial sun to full sun
Persistence Deciduous

Bloom Color White
Bloom Time Summer

The flowers are very showy, suitable for cut flowers and suitable for dried flowers.

EnvironmentThis plant tolerates some drought.
This plant will grow in dry soil.
Suitable soil is well-drained/loamy, sandy or clay.
The pH preference is an acidic to slightly alkaline (less than 6.8 to 7.7) soil.

Leaf Color Green
Fall Color Yellow

Culture NotesPanicle Hydrangea should be grown in full sun or partial shade on well-drained, moist, loamy soil. Plants flower best in sun. The upright, spreading branches often bend down with the weight of the blooms, and the brown, faded blooms should be removed in late September to keep the tree from looking unkempt. If unpruned some people object to the pinkish brown fruits and old flowers which hang on to the tree during the winter. Pruning also is suggested to keep the plant to a consistent, neat shape. Lower branches can be pruned to clean up the bottom of the plant and make it grow into a multi-stemmed tree. Flowers emerge white and turn pink.
This plant is considered mostly allergy free and causes little or no allergy problems in most people.

Planting and establishing shrubsThe most common cause of young plant failure is planting too deep. Plant the root ball no deeper than it was in the nursery. In most instances, the root flare zone (point where the top-most root in the root ball originates from the trunk) should be located just above the landscape soil surface. Sometimes plants come from the nursery with soil over the root flare. If there is soil over this area, scrape it off. The planting hole should be at least twice the width of the root ball, preferably wider. In all but exceptional circumstances where the soil is very poor, there is no need to incorporate anything into the backfill soil except the loosened soil that came out of the planting hole.

Perennial Of The Day

Gazania rigens syn. Gazania ringens; Gazania splendens 'Daybreak Red Stripe'
Treasure Flower, Gazania


Type Perennial
Hardy range 7A to 9A
Height 6" to 12" / 15cm to 30cm
Growth rate Average
Form Upright or erect
Exposure Full sun

Bloom Color Red and yellow
Bloom Time Summer and Fall

The flowers are showy.


EnvironmentThis plant tolerates drought and salt well.
This plant will grow in dry to moist soil.
Suitable soil is sandy.
The pH preference is a neutral soil.

Leaf Color Green and silvery

Culture NotesThe well known garden plant Gazania splendens (or "rigens") originates in South Africa. The petals are usually orange, yellow or white, but sometimes bronze or pink. At the base they are often brown forming an attractive ring at the center. The flowers close in darker weather and opens again with the first rays of the sun. "Daybreak", called after this surprising effect of the sunlight, is one of the most well known Gazania hybrids.
'Daybreak Red Stripe' is a really unique variation of this Gazania series, with a red stripe dissipating out over each deep yellow petal. This gives the startling effect of a radiating sun when the flowers open.
It is the third Gazania from the 'Daybreak' series to win a Gold Medal from Fleuroselect, the international organization for testing new flower seeds. The golden-yellow 'Garden Sun' from 1990 was only emanated in 1996 by 'Bright Orange' which bloomed earlier, richer and more uniformly than any other seed Gazania. The new 'Daybreak Red Stripe' yet again beats its predecessors in beauty, keeping the compact form, and countless, large, single flowers, which open earlier than other Gazanias. This richly flowering and unusual plant therefore shines in the garden, even before the penetration of the first sun's rays.
If sown in January, 'Daybreak Red Stripe' can be planted out from May (end of the frosts). To germinate, the seeds should be covered lightly and kept damp at 21 ° C. After 3 weeks the seedlings can be transferred to 9 cm pots or sets (16 or 24). Growth regulators are not required. Hobby gardens can expect later flowering due to lower temperatures during the growth period. Gazanias perform well in borders, rockeries and in pots. They can withstand dry conditions, salty air and wind and have a preference for a sunny spot and well-drained soil.
