Three witch hazels are in flower now. Both are growing near the parking lot.
Two Hamamelis vernalis, known as Ozark witch hazel, grow on the slope near the Carriage House and are covered in bright yellow flowers that look like "wrinkled stars" (click on any image to view a larger version):
From the Missouri Botanical Garden website: Hamamelis vernalis, commonly called Ozark witch hazel, is native to the Ozark Plateau extending from southern Missouri through northwestern Arkansas to eastern Oklahoma.
Hamamelis virginiana ‘Mohonk Red’ grows near the sugar maple across the drive from the Ozark witch hazels and has been in flower since late fall.
Here is some interesting information about these plants from the Missouri Botanical Garden website:
Hamamelis virginiana, known as common witch hazel, is a fall-blooming, deciduous shrub or small tree that is native to woodlands, forest margins and stream banks in eastern North America. It typically grows 15-20’ tall with a similar spread in cultivation, but can reach 30’ tall in its native habitat. Stem-hugging clusters of fragrant bright yellow flowers, each with four crinkly, ribbon-shaped petals, appear along the branches from October to December, usually after leaf drop but sometimes at the time of fall color. Fertilized flowers will form fruit over a long period extending through winter and into the following growing season. Fruits are greenish seed capsules that become woody with age and mature to light brown. Each seed capsule splits open in fall of the following year, exploding the 1-2 black seeds within for up to 30 feet. Oval to obovate, medium to dark green leaves (to 6” long) with dentate to wavy margins turn quality shades of yellow in fall. Plants of this species are usually the last native flowering plants to bloom in Missouri each year.
Genus name comes from the Greek words hama meaning at same time and melon meaning apple or fruit in reference to the occurrence of both fruit and flowers at the same time on this shrub (particularly in the case of fall flowering members of the genus).
Specific epithet means from Virginia.
‘Mohonk Red’ is a red-flowered cultivar. It was discovered at the Mohonk Nature Preserve in New Paltz, New York, and subsequently introduced into commerce by the Arnold Arboretum. Lightly scented flowers are red shading to light yellow at the petal tips. Rounded to obovate, pale green leaves emerge in spring, mature to dark green by summer and turn yellow in fall. This shrub will typically grow to 9' tall and as wide during the first 10 years, eventually maturing over time to 15-20' tall
