Plant of the Month
Grid S6 five vines growing on the southern section of the Asian pergola
These vines are closely related to the fuzzy green Kiwi fruit that are now quite common in produce aisles. These also have edible fruit, but they are much smaller than their fuzzy relatives, and the skin is smooth, so they can be eaten like a grape. They are at their peak flavor after a light frost in the fall.

The Hardy Kiwi in the Arboretum are part of a collection of plants known as the NACPEC collection. A consortium of Arboretums, known as the North America-China Plant Exploration Consortium (NACPEC) was formed to collect seeds from wild populations in China. They solicited sponsorships and seeds from the collections were shared with the sponsors. The Arboretum Associates provided the funds for the sponsorship, and a number of plants in the Asian section of the Arboretum were grown from those seeds. Most of the vines on the pergola are part of that collection.
Male flowers, Actinidia arguta 6-20-14
All Kiwi are dioecious, which means plants are either male or female, that is somewhat unusual in plants, which often have both sexes within one flower. Both male and female plants are required for pollination, and luckily we have both in the five plants.
June has been remarkably nice this year with some timely rains and pleasant temperatures. Our irrigation system is slightly handicapped, resulting in lower pressure, so the rain has been very beneficial. We are still busy planting new additions and preparing for more plants. We should finish planting the Harley Wright memorial by the end of the month down at the south end of the Arboretum. It will be a collection of new cultivars of Russian Sage (Perovskia atriplicifolia) combined with new cultivars of Japanese Barberry, both purple and gold leaf varieties.
