Two-winged silverbell, Halesia diptera

 

Westonbirt Halesia diptera

 

One of June’s most beautiful white flowers is the Two-winged silverbell. Their showy clusters  (3 to 6 flowers per cluster) of bell-shaped flowers appear in June and are followed by flattened two-winged fruits.

This plant is native to floodplains, stream banks, wet woods and swampy areas primarily along the Gulf Coast from South Carolina and northern Florida west to Texas.

Its name comes from the Greek words di meaning two and ptera meaning wings, in reference to the two-winged fruit of this plant. The genus name honours the Reverend Stephen Hales (1677-1761), an English physiologist, chemist, and inventor.

See it  in Sand Earth (location 21M) and off Circular Drive (location 17D).

 

 

The Wheel Tree, Trochodendron aralioides

 

Westonbirt Arboretum Trochodendron aralioides

 

Known as The Wheel Tree due to its fruits, which look like a spoked wheel.

They are lime green in colour and stand out against the evergreen leaves with their attractive scalloped edge.

Native to Japan, Korea and Taiwan, this is a very old species; an imprint of its leaf was  found in a 49 million-year-old fossil discovered in Washington State, USA.

Our specimen can be seen on Main Drive, location 18F/E.

 

 

Cornus kousa

 

 Westonbirt Cornus Kousa

 

After the glorious technicolour of May’s Rhododendrons June is a quieter month, but the flowering dogwood Cornus kousa is one of its stars. The showy parts of the “flower” are the four narrowly pointed petal-like white bracts which surround the centre cluster of insignificant, yellowish-green, true flowers.

It was first collected in Japan in 1875.

We have several specimens in Silk Wood and in Old Arboretum, but the largest and best is tucked away off Mitchell Drive just beyond Down Gate, location 22G.
