Plant Profile: Spireae thunbergii ‘Ogon’ (Spirea 'Mellow Yellow')

Spireae thunbergii ‘Ogon’ (Spirea 'Mellow Yellow')





The wispy spreading branches of the 'Ogon' are covered with thousands of tiny white flowers in early spring - and last for a few weeks - just before the showy golden yellow leaves appear. And in the fall, the foliage color is almost psychedelic - shades of gold, rusty red and orange.



(Forgive the blurry image, but above is Spirea 'Mellow Yellow' turning colors in the early fall and below is the final fall show!)



Grown in sun or shade, drought-tolerant, and all-around tough plants - all varieties of Spirea are the kings of low-maintenance plants. We joke that you just can't kill these shrubs! However, a good shearing after the 'Mellow Yellow' is done blooming will keep the shrub compact and neat looking (The flowers bloom on old wood so try not to prune it in the summer or fall.)



If you leave the shrub unpruned, it has arching, wispy branches covered with fine textured chartreuse foliage in the summer, and the shrub will reach 3 to 5 feet tall and wide.

It attracts butterflies, bees, and other pollinators.

Attract Butterflies to your Garden

Attract butterflies to your garden with late summer blooms -asclepias (butterfly weed), Buddlia (butterfly bush), Heliopsis, and Helenium.

Butterfly Garden Necessities:

*Plant native flowering plants - Dense "clusters" of small flowers such as zinnias, marigolds, tithonia, buddleia, milkweeds, verbenas and many mint family plants generally work well. Because many butterflies and native flowering plants have co-evolved over time and depend on each other for survival and reproduction, it is particularly important to install native flowering plants local to your geographic area. Native plants provide butterflies with the nectar or foliage they need as caterpillars and adults. Adult butterflies may accidentally mistake a non-native, invasive plant for a good egg-laying site, which could prevent the survival of its offspring. Grow your nectar-producing native plants in sunny areas that are protected from strong winds. The Lady Bird Johnson Wildflower Center has lists of recommended native plants by region and state.

*Plant type and color is important – Adult butterflies are attracted to red, yellow, orange, pink and purple blossoms that are flat-topped or clustered, and have short flower tubes.

*Plant good nectar sources in the sun - Your key butterfly nectar source plants should receive full sun from mid-morning to mid-afternoon. Butterfly adults generally feed only in the sun. If sun is limited in your landscape, try adding butterfly nectar sources to the vegetable garden.

*Plant for continuous bloom - Butterflies need nectar throughout the adult phase of their life span. Try to plant so that when one plant stops blooming, another begins.

*Say no to insecticides! - Insecticides such as malathion, Sevin, and diazinon are marketed to kill insects. Don't use these materials in or near the butterfly garden or better, anywhere on your property. Even "benign" insecticides, such as Bacillus thuringiensis, are lethal to butterflies (while caterpillars).

*Feed butterfly caterpillars. - If you don't "grow" caterpillars, there will be no adults. Bringing caterpillar foods into your garden can greatly increase your chances of attracting unusual and uncommon butterflies, while giving you yet another reason to plant an increasing variety of native plants. In many cases, caterpillars of a species feed on only a very limited variety of plants. Most butterfly caterpillars never cause the leaf damage we associate with some moth caterpillars such as bagworms, tent caterpillars, or gypsy moths.

*Provide a place for butterflies to rest – Butterflies need sun for orientation and to warm their wings for flight. Place flat stones in your garden to provide space for butterflies to rest and bask in the sun.

* Give them a place for puddling – Butterflies often congregate on wet sand and mud to partake in "puddling," drinking water and extracting minerals from damp puddles. Place coarse sand in a shallow pan and then insert the pan in the soil of your habitat. Make sure to keep the sand moist.
