I think the Island of Hawaii is one of the most magical places on Earth. You can literally see land in the making when one of the volcanoes is erupting. But the familiar sight of red-glowing lava flows makes it hard to imagine a time when eruptions were different, and to think that such a time may come again someday.

Palms are a key component of Hawaiian gardens, and it was date palm (Phoenix dactylifera) leaves used to greet Jesus as he entered Jerusalem the Sunday before Easter. Date palms are not often used in the typical garden because nurseries seldom carry them. On the other hand, the pygmy date palm is much more delicate, smaller and popular. Pygmy date palms (Phoenix roebellini) fit well in limited spaces and are slow growing, so consider them in that they are drought and wind tolerant. They will tolerate full sun and shady locations as well. However, the date palm of the Middle East and other dry regions of the tropics or subtropics should not be ignored. It is extremely tolerant of dry, windy and salty locations where most other palms would not survive. They can be grown from seed if you have the patience. At Spencer Park in South Kohala, there are fruiting specimens that actually produce edible dates. Collecting seeds there is an option for a fun project.

Hawaii is famous throughout the world for its beauty, friendly people and for the varied climate that is ideal for almost all the palms on the planet. This Oct. 10-19, the International Palm Society is celebrating its 32nd biennial meeting here. Every two years, members from all over the world meet to learn about this amazing family of plants. They meet in such exotic places as Thailand, Brazil, Madagascar and New Caledonia. This year they will focus on the rare endemic genus Pritchardia. To get involved in this year’s events, go to the IPS website, palms.org for details.

The 35-year-long Pu‘u‘o‘o eruption on the middle East Rift Zone of Kilauea was a remarkable opportunity for scientists to improve volcano research and monitoring. Even short-lived episodes in this eruption, like the four-day-long Kamoamoa eruption, offered important insights. For the 11th anniversary of the Kamoamoa eruption, this week’s “Volcano Watch” highlights the episode and some of the data collection.

It seems just when we think we have dealt with one epidemic another pops up. The avocado lacebug caused widespread defoliation of avocado trees in 2021, and now we have a new pest attacking our native koa, wili wili and uhiuhi. The acacia whitefly (Tetraleuodes acacaciae) has become widespread on Oahu and will soon be found on the Island of Hawaii if it is not already here. Not only does it attack our native acacia koa, other hosts include the shower tree (Cassia species) and related legume trees like the bauhinias are vulnerable as well. Acacia whitefly infestations may cause leaf yellowing, wilting and even defoliation.
