Pineapple Lily

Pineapple Lily Different view of a Pineapple Lily

Pineapple Lilies are a group of summer flowering perennials that are truly a show stopper. Our guests to the garden keep asking about this unusual plant. In the early spring this bulbous perennial's leaves appear and make you ask "What is it"? Then the long flower stem starts to appear sporting blooms that really do resemble the fruit of a pineapple. It is winter and summer hardy, but does seem to appreciate afternoon shade.

You can find these plants in our Entry Garden and along the walk around the pond and Boulder Garden. (2016)

Loosestrife, Purple

Purple Loosestrife

Purple loosestrife is an erect perennial herb in the loosestrife family, with a square, woody stem and opposite or whorled leaves. It's leaves are lance-shaped, stalk-less, and heart-shaped or rounded at the base.

Loosestrife plants grow from four to ten feet high, depending upon conditions, and produce a showy display of magenta-colored flower spikes throughout much of the summer. Flowers have five to seven petals. Mature plants can have from 30 to 50 stems arising from a single rootstock.

In the wild this plant is widely recognized as an invasive species that is difficult to control. However, horticultural species such as ours are sterile and can be used in your garden.

This plant can be found near the pond on the lower path.(2016)

Phlox, Robert Poore

Robert Poore Phlox

The name phlox is derived from the Greek word for flame. 'Robert Poore' is a garden phlox cultivar that typically grows in an upright clump to 3'-4' tall. Fragrant, tubular flowers with long corolla tubes and five flat petal-like lobes are violet-pink. Individual flowers are densely arranged in large, terminal, pyramidal clusters in summer atop stiff, upright stems which seldom need staking.

It is a good fresh cut flower and is a staple of the perennial border. Mixes well with other perennials and provides long summer bloom. Regardless of flower color, garden phlox is attractive to hummingbirds and is a good selection for inclusion in a bird garden.

This plant is located in the Boulder Garden right next to the steps leading down to the barn.(2016)

Clematis, Jackmanii


This classic Clematis is considered by many to be the truest and most beautiful of all and has been loved by gardeners for more than 100 years. It is an absolute spectacle of masses of Royal Purple blooms for 4 full months (June through September). This is a Clematis you want to blanket your fences and outbuildings because it eventually reaches 12 to 30 feet high and 4 to 5 feet wide - it is not a plant for the mailbox.

The blooms are excellent for cutting - just float them in a bowl of water for a lovely table centerpiece. It is best planted in light (not deep) shade, such as that provided by high canopies of tree branches.

You can view this beauty on an arch in the Fountain Garden. (2016)


Crimson Flood and Lemon Berry Frost Daylily

Crimson Food and Lemon Berry Frost Daylily

Who doesn't enjoy a bed full of colorful daylilies.

No investment in perennials pays off like one in daylilies: foliage that looks great all season, flowers in a rainbow of colors, no special care and now, many that reward you with both a spring and fall season of bloom. "Reblooming Daylilies" are just what they claim. Most have a big bloom during regular daylily season in late spring, and then bloom off and on for the rest of the season, usually with a burst of bloom before fall.

The 6" bright yellow blooms of the Glory Bright Daylily are irresistible. They are very heavily ruffled with the ruffle often being 3/4" wide. Scapes have 3 and 4 way branching with 25 buds. This daylily is a must have if you love yellow.

But whether yours are the old favorites or the brand new ruffled-up fancy faces, they'll all reward you with a big perennial show for very little care. And since they don't demand absolute full sun, daylilies also let you sneak some of the color back into shady areas, making them one of the best shade perennials.

Crimson Flood and Lemon Berry Frost are blooming next to the fence in the Boulder Garden. Glory Bright 'Yellow' can be found in the Fountain Garden(2016).



Pentas are semi-tropical shrubs grown as annuals that seem to be tailor-made for butterflies and humming birds. The nectar-rich flowers grown in clusters over a long blooming season in vibrant red, pink, and purple shades that act like a beacon to butterflies and humming birds.

If you want an annual that is up to Tulsa's heat in the summer and can still look gorgeous in August this is your plant.

Just take a look at our entry garden and how inviting this mass of flowers is after all our heat.

Coneflower, Henry Eilers

Henry Eilers Coneflower

Henry Eilers Coneflower is a sweet coneflower cultivar that typically grows to 3-5’ tall on stiff, upright, leafy stems. It was found growing in the wild in a railroad prairie remnant in Montgomery County, Illinois. The flowers’s yellow rays are rolled instead of flat, giving the flower a quilled effect. The center disks are dome-shaped, and bloom in clusters atop strong, sometimes-branching stems from July to September. Dark gray-green leaves (3-6” long) have a mild sweet aroma. The cultivar was discovered by Henry Eilers, a well-known nurseryman in southern Illinois, and was introduced by Larry Lowman of Ridgecrest Nursery and Gardens in Wynne, Arkansas in 2003.

This can be seen in the Fountain Garden (2016)

Hydrangea, Glowing Embers and Endless Summer

Glowing Embers
Glowing Embers

The popularity of these big, bold plants has grown within the last few years since the new varieties are more hardy and mildew resistant. Hydrangeas should be sited in moist, rich garden soil in partial sun to fairly deep shade. Hydrangeas can be categorized into 4 different types: Mophead, lacecap, Oakleaf and panicle.

Strawberry fall blooms

Vanilla Strawberry Hydrangea is a hybrid of an easy-growing, sun-loving hydrangea species. The unusual colors in the blooms of Vanilla Strawberry hydrangea distinguish this showy summer-flowering shrub.

Rose of Sharon (Althea)

Rose of Sharon

The 10' tall shrub is not actually a rose but is in the Mallow Family and is sometimes called "Shrub Althea". Carl Linnaeus classified Hibiscus syriacus in the 18th century based on a herbarium specimen from Syria to which the species apparently had been imported long ago, since its origins are from India and East Asia.

Rose of Sharon comes in many colors - especially white, lilac, and pink. It occurs as a single flower, or as a hybridized double. Blooms first occur in late spring and continue through early fall, making Rose of Sharon one of the few summer-blooming shrubs.

Individual blossoms open in early morning, close at night, and usually last less than three days. Regardless of the flower's color, there is almost always an intensely maroon central spot formed by a concentration of pigment at the bases of five large petals. The almost-triangular serrated leaf of Rose of Sharon is semi-glossy dark green and about 3" long. The foliage is also deciduous. Rose of Sharon goes into a very long resting period and is one of the last shrubs to green up in spring.

Trimmed Rose of Sharon

Rose of Sharon is a great plant that can be pruned to show off its multi-trunks. We have several examples in our garden. Treeing it up enables the eye to see through the branches to any hardscaping or plants behind it to give the view a layering look.

This white Rose of Sharon, called Helene, can be found in the Boulder Garden along the west stream near the Greenhouse. Not far away is a lovely violet variety called Aphrodite. Both are low maintenance and tolerate deer, drought, and clay soils. (2016)

Smoketree, Grace

Cotinus Smoketree Gracie

Grace Smoketree (Cotinus coggygria x obovatus 'Grace') is an elegant hybrid of the European and North American species. Light red spring foliage matures to rich wine-red leaves. These evolve to a showy mix of orange, red, purple and golds in the fall. Frothy purplish-pink clusters of flowers resemble smoky plumes, adding drama to the landscape in midsummer. Upright and spreading, this low-branched tree develops a rounded head as it reaches about 20 feet in height with a 15 foot spread.

Like all smoke trees, Cotinus 'Grace' is disease free and drought tolerant. It requires full sun and will not grow well in shade. In low light conditions it has a lax habit and will not flower or develop foliage color. Cotinus 'Grace' will grow in a wide range of soils with average fertility.

You can locate it at the top of our Boulder Garden.(2016)

Rosa 'Chuckles'

Rosa 'Chuckles'

Rosa 'Chuckles' is an ever-blooming dark pink rose from May to September that does well in mass plantings (grows to three feet tall) and is tolerant of light shade. It is a floribunda rose with single flowers (petal count 5-11) that are 2-3 inches in diameter held in large clusters toward the tips of the canes. For fall and winter interest, bright red fruits hang on through the winter.
