What's Blooming at the Los Angeles County

March 2007
Page One

NOTE: Work has begun on the new Madagascar garden which is scheduled to be open to the public in May. It will be very interesting to see what kind of weird new plants will be on display. Madagascar has a fascinating and diverse flora, between 8,000 and 12,000 species, of which 70-80% are endemic. 10 families and 260 genera of plants are endemic to Madagascar. However, the state of Madagascar's flora is not good, with only remnants of the island's original forests still remaining, and many areas having been extensively covered by aggressive invasive species from places like Australia. Hopefully, measures will be taken to preserve this fantastic habitat. While waiting for this garden to be completed, enjoy the rest of the Arboretum. As the large number of pictures in this month's photo gallery demonstrate, there are lots of things blooming.

The Ericaceae is known as the heather or heath family. It is a huge family with some 125 genera and as many as 3,500 species, and is present mostly in temperate regions from all over the world except Australia. Members of this family typically have woody stems, simple and alternate leaves, and flowers with 4-5 petals, but they can also have opposite and needle-like leaves They are also usually found in acidic soils and are dependent on fungal mycorrhiza. Bogs and moors are places where heathers are often found. The flowers of many species look like little bells, and pollination is generally by insect or wind. Some of the more notable genera are Arctostaphylos (manzanita), Rhodo- dendron (azaleas and rhododendrons), Erica (heath), and Vaccinium (cran- berries, huckleberries and blueberries). Most of the Rhododendrons are from China and most of the Ericas are from South Africa.
