Kirengeshoma koreana

Kirengeshoma koreana, commonly known as yellow wax bells, is a delightful, rhizomatous perennial from Korea. Its exquisite, drooping golden-yellow flowers, each with four reflexed petals surrounding a bright yellow center, dangle from long stems and bloom from July to October. Its palmately divided green foliage is attractive as well. This shade loving beauty prefers moisture-retentive, well-drained soil and light afternoon shade. Though it is short-lived, it's worth the effort of regular dividing and propagating for its long blooming period. Kirengeshoma will make a real showstopper in any garden!

watering

Kirengeshoma (Kirengeshoma koreana) should be watered moderately, about once a week during the growing season (from early spring to early fall). It prefers well-drained, slightly moist soil, so ensure that the soil surface is allowed to dry out in the intervening days before watering again. During the winter, water the plant only when the soil feels dry to the touch. Do not allow its root ball to sit in soggy soil. Overwatering can lead to root rot and other health issues, so carefully monitor the moisture content of its soil as you water.

sunlight

Kirengeshoma (Kirengeshoma koreana) does best when exposed to full sun for at least 5-6 hours per day. They will also tolerate light shade for part of the day, but too much shade will usually reduce both flowering and leaf color. If possible, aim for bright, indirect light, especially during the heat of the day, as direct exposure to full sun can cause the leaves to burn during mid-day.

pruning

When it comes to pruning kirengeshoma, it is recommended to wait until late winter to early spring (before any new growth appears) to prune old, dead, or diseased stems. Prune away any old flower stems and any stems which are crossed over each other, as this can lead to the plant becoming lopsided. Depending on the size and shape of the plant, you may want to lightly trim the longest branches. In general, you should prune no more than 1 third of the plant, as over-pruning can lead to a loss of both vigor and bloom.
