My wife and I started gardening in Fukuoka (Japan) in 2003. There was nothing but muddy clayey sloping land. At the beginning we made several structure such as steps and paths, and planted turf, fruit trees, roses, herbs etc.
In 2010, we visited several famous English gardens, including Sissinghurst Castle Garden, Mottisfont Abbey Garden and Hidcote Manor Garden. We were shocked by the glory of those gardens. Since then, we have been trying to make little but glorious gardens by ourselves.
YELLOW BUTTERFLIES LOVE ACACIA (キチョウはミモザがお好き）
We grow Acacia baileyana in a large pot in front of the brick wall.
Many yellow butterflies fly around there, and I wondered why they come.
One day I found a green & yellowish pupae beneath leaves,
and kept them in a transparent plastic case.
In several days, a yellow butterfly emerged.
I freed it from the case and laid it on the leave of acacia.
Within an hour, another yellow butterfly came and mate it.
I checked its ecology on internet, and I found that Eurema hecabe likes bean family plants including acacia -- I am convinced!
