addition to a "Research Forest Station" and a "Healer's Hut" (designed to educate visitors about various cultural topics), there are two waterfalls, several bridges, a stream, and a wide variety of plants from bamboo, orchids and frangipani to plants of economic, cultural, and horticultural value to the people of Thailand. The second theme is "Headwaters of the Amazon," which opened in early 2009. In 2007, Phipps teamed with glass artist Dale Chihuly and his Tacoma-based team of glass blowers. They worked together to create a marriage of hand-blown glass and living plants. Following the closing of the exhibit in February, the conservatory retained four prominent pieces (the Welcome Center chandelier, the hanging gold star in the Desert Room, the celadon and purple gilded Fiori in the Tropical Fruit and Spice Room and the bronze, apricot and chartreuse Ikebana in the Palm Court) and subsequently purchased 26 smaller pieces for its permanent collection including six multicolored Macchia (wavy, shell-like bowls), thirteen amber Cattails and seven Paintbrushes, all of which are installed in the Palm Court. The total Chihuly collection is valued at $1.2 million. In 2009, Phipps teamed with another glass artist Hans Godo Frabel to create another stunning exhibit titled "Gardens and Glass." Unlike the Chihuly pieces, Frabel's work is more realistic, although still whimsical at times. Highlights of this exhibit include Longfellows, intricate glass orchid and lotus plants and various clowns (balancing on either glass playing cards or colored glass balls.) This collaboration was on display until January 2010. Indoor Gardens Palm Court The Palm Court is the first room visitors see after entering the Conservatory through the main entrance. The Victorian-inspired room contains many species of palm trees. The room contains the original dated plaque from the Conservatory's opening as well as numerous glass installations by Dale Chihuly. To accommodate the palm trees, the Palm Court has a high glass peak. The original wood and annealed glass in the Palm Court had deteriorated to a point for the need of emergency stabilization in 2008. Renovations began in 1992 and included replacing the upper wood and glass vent sash with aluminum and safety glass, and replacing the vertical wood and glass components with new replicated aluminum extrusions and safety glass glazing to match the original specifications exactly. Serpentine Room The Serpentine Room is located west of the Palm Court, connecting it to the Fern Room. The exhibits in the
