What's in Bloom

What's in Bloom Archives

With cool weather and shorter days, our fall blooms are coming into their own. (as of 10/13/16)

Raydon's Favorite Aster

Raydon's Favorite Aster

Aster oblongifolia, aromatic aster, is a dependable herbaceous perennial that displays a wonderful fall flower show. If you depend on pots of mums and pansies to color your perennial garden in the fall, you're missing out on a great show of color that this aster will provide.

It is just reaching peak bloom and it is simply magnificent. One can hardly see any foliage for the massive coverage of rich blue flowers and the leaves have a pleasant minty fragrance when crushed.

If you want to mimic this look for your landscape, most medium to large growing asters should have their succulent spring growth pinched or sheared back several times before July 4th. Pinching off lush early growth will cause asters to branch and produce thick, stout branching and maximum fall blooms.

Tatarian Aster

Tatarian Aster

Aster tataricus, the goliath of the asters, is an upright growing variety that can easily reach five to six feet in height and three feet wide.

One of the latest bloomers, this aster explodes with lavender-blue, yellow eyed blossoms in flat clusters, each flower the size of a half dollar which is easily supported by its stiff upright growth. Asters are good nectar plants attracting butterflies and bees. Ours have been covered with monarchs.

Location: Boulder Garden and Fountain Garden.(2016)

Rose Creek Abelia

Rose Creek Abelia

Here is a wonderful perennial with lustrous leaves that emerge with a pinkish cast on crimson stems. It matures to dark green, then turns purple-green in winter.

Our Rose Creek Abelia has been smothered in flowers from mid-summer into fall. It attracts butterflies and bees. It is truly star quality plant.

It is an excellent foundation plant for continuous seasonal change beneath windows, or to use with a mixed shrub border, or try as a low hedge. Plant it in full to partial sun.

Autumn Carnation Encore Azalea

Autumn Carnation Encore Azalea

If you love Azaleas in the spring, you will be amazed with the new Encore Azaleas.

Fall is here and these Azaleas are in full bloom near the wall outside the deck overlook in our Linneaus Garden. With blooms in the spring, summer, and fall, Encore Azaleas offer little maintenance and big color.

Autumn Carnation has an exceptional flower quality, color, and lustrous dark green foliage which make this variety an excellent landscape addition. Encore Azaleas are easy to grow, and they adapt to most conditions. They prefer slightly acidic well drained soils and require once a year feeding of a slow release fertilizer.

After the spring blooming period, these amazing azaleas begin growing new shoots and start blooming into full flower in mid-summer.(2016)

Amazing. Our Garvinea has bloomed all summer and it still looks great in October.

Would you like some color in your garden? It's easy with Garvinea. Garvinea is a revolutionary new gerbera with a unique combination of features. Using genetics from wild South African plants, breeders have managed to come up with a color palette of strong, prolific, free flowering gerberas which have cold tolerance and superior pest and disease resistance.

Garvinea are happy in full sun to part shade and look gorgeous mass planted in garden beds and large containers. What Garvinea lacks in flower size compared to other gerberas is more than made up for by the quantity of flowers, with each plant yielding well over 70 blooms per year. They provide continuous color from spring right through summer to the end of autumn. Garvinea are winter hardy and survive where temperatures may drop to -5°C. Come spring the flowers will start popping up for another long season. Being pest and disease tolerant means that Garvinea are much easier to grow than most other gerberas.

You can find Garvinea on the sunny side of the Entry Garden above the driveway test beds.(2016)

Osteospermum White Lightning and Blue-Eyed Beauty

 Osteospermum White Lightning

Osteospermum White Lightning - in November after first frost

Grow White Lightning in any climate.

Cheery crisp white daisy blooms with a yellow center are striking even “asleep,”. Its yellow undersides makes it appealing even when the flower is closed on cloudy days. And it presents well when the flowers partially close and both colors are visible.

Osteospermum White Lightning also looked great in the Linnaeus Garden well into the fall. After our first frost in early November, it looked as crisp and cheerful as it did in summer.

Osteospermum Blue Eyed Beauty

Osteospermum Blue-Eyed Beauty, yellow with blue eyes

These prolific plants produce stunning flowers all summer long.

The Osteospermum Blue-Eyed Beauty is a one-of-a-kind African daisy with stunning blue eyes, that also continues blooming from early spring through autumn. These prolific plants mound 12"-14” and produce armfuls of really pretty cut flowers that will be the talk around your dinner table; meanwhile, back in the garden, these plants are star performers in both sun and shade.

You can find these fresh daisy-like flowers above our test beds along the curved drive outside the fence.(2016)


Lantana Bandito Rose

Lantana Bandito Rose

Lantana - Little Lucky Lemon Cream

Little Lucky Lemon Cream

Lantana is a genus of about 150 species of perennial flowering plants in the verbena family, Verbenaceae. In our Tulsa zone they are usually considered annuals because of our colder weather in the winter. If we have a mild winter this plant can come back in the spring.

Lantana's aromatic flower clusters (called umbels) are a mix of red, orange, yellow, or blue and white florets. Other colors exist as new varieties are being selected. The flowers typically change color as they mature, resulting in inflorescences that are two- or three-colored. If you have a hot, baked spot, lantana is your answer. This hardworking plant not only thrives with little moisture and in full, unyielding sun, it does so with ease.

In fact, lantana is a flower that seems to have it all: it produces an abundance of brightly colored flowers all summer and fall; it's a magnet for butterflies and hummingbirds; it's easy to grow and a great choice for containers.

Lucky Lemon Cream and Bandito Rose Lantana are newly introduced varieties. They bloom up to three weeks earlier than other compact lantanas. They bloom from spring through fall and grow in a mounded compact shape.

Specimens are located in beds outside the gates along the curved drive below the Entry Garden. The butterflies have been abundant.(2016)
