The devoted gathered to hear Mr. Baldwin of the premiere West Coast nursery San Marcos Growers<\/a> give a talk at Roger’s Gardens<\/a> last Saturday on new plant introductions. Be warned that this post will be plant-wonkish in the extreme.<\/p>\n

SMG is a wholesale operation and, with few exceptions, unfortunately open to the trade only, which is why I pounced at the chance to hear Mr. Baldwin speak. Their website is an incredible resource, one that I refer to frequently on my blog. Many of the following plant introductions are from Australia. The Mediterranean climate<\/a> of parts of Australia offers the perfect hunting ground for plants suitable for growing in Southern California’s own Mediterranean, winter\/wet, summer\/dry climate.<\/p>\n

This may be a little clumsy, but I’m going to try to use the above photograph to point to a few of the plants he discussed.
\nI have zero tech chops for adding labels, arrows, or any other useful bells and whistles. Much of the description is straight off the handout that Roger’s Gardens prepared from SMG’s website.<\/p>\n

First row, the three shaggy plants on the left. (Just in front of the burgundy Cordyline ‘Design-a-line Burgundy’):
\nAcacia cognata ‘Cousin Itt<\/a><\/strong>,’ Little River Wattle. Tight growth to 2 to 3 feet tall by 3 to 6 feet wide.
\nLight green, sometimes red-tinged new growth that matures to a rich emerald green.
\nNot yet noted in bloom but likely to have the pale yellow flowers of the species.
\nFull sun\/part shade, well-drained soil. Occasional irrigation after established.
\nLiterature lists as hardy to 15F, but SMG feels tips will freeze at 20-25F, which will not be damaging to this shrub form and only serve as a light pruning.
\n(The tree Acacia cognata<\/a> is directly behind Mr. Baldwin, tallest of the plants pictured.)<\/p>\n

Norfolk Island Pine-looking tree behind Mr. Baldwin, to his left.
\nWollemia nobilis<\/a><\/strong> (Wollemi Pine). One of the world’s oldest and rarest plants, this conifer discovered in 1994 in the Blue Mountains west of Sydney, Australia, elicited much discussion from the audience. Previously only known in the fossil record, discovered by David Noble, a National Parks & Wildlife Services Officer in the Wollemi National Park. A member of the Araucariaceae (as is the Monkey Puzzle Tree). “A fast-growing conifer that sprouts multiple trunks to 130 feet tall with bubbly brown bark and bearing new growth of flat sprays of oppositely ranked soft needles that are at first apple green but age to blue-green much like a coast redwood (Sequoia sempervirens) or Chinese plum yet (Cephalotaxus fortunei). As trees age, the mature foliage is distinctly different, looking more like that of the related Araucaria, with leaves more yellow green, stiffer and held upright in 4 ranks. It is at the tips of these mature branches that cones, both a male and a female, would form.”
\nLight shade to full sun, well-drained soil, preferably acidic, allow to dry between irrigation. To 23F but trials in other parts of the world indicate it can tolerate as low as 10.4F.<\/p>\n

First row on the left, last plant on the end after the three ‘Cousin Itt.’ Adenanthos cuneatus ‘Coral Drift’<\/a><\/strong> (Flame Bush)
\nI managed to grab a quick photo of this one.<\/p>\n

\"Photobucket\"<\/a><\/p>\n

2007 University of California at Santa Cruz “Koala Blooms”<\/a> Australian plant introduction. (According to Mr. Baldwin, a great source for Australian plants is Australian Native Plants<\/a> in Ventura, California.)<\/p>\n

This adenanthos is a low-growing shrub to 2 to 4 feet tall by 3 to 5 feet wide. A common coastal plant along the south coast of Western Australia, this selection was made for its bright pink new growth and compact, spreading habit. Full sun, well-drained soil, drought tolerant when established. Speculated to be hardy to 15-20F.<\/p>\n

Other plants discussed by Mr. Baldwin can all be found on the San Marcos Growers website, links provided:
\nAgave ‘Mateo’<\/a> (bracteosa X lophantha hybrid). Mr. Baldwin says SMG is scaling back on agaves in response to less demand (say it isn’t so!) and pushing aloes instead.
\nAgonis flexuosa ‘Jedda’s Dream’<\/a> (Dwarf Red Peppermint Tree)
\nAgonis flexuosa ‘Nana’<\/a> (Dwarf Peppermint Tree)
\nBeaucarnea ‘Gold Star’ (Variegated Bottle Palm)<\/a> – extremely sexy.
\nBerzelia lanuginose<\/a> (Buttonbush)
\nCordyline ‘Design-a-line Burgundy’<\/a> – (Cultivar naming rules: No more than three separate names, so must hyphenate!)
\nLomandra hystrix ‘Tropic Belle’<\/a>
\nLomandra longifolia ‘Nyalla.’<\/a> (Very tough. Grown under eucalypts at Lotusland.)
\nPhylica arborea<\/a> (Island Cape Myrtle)
\nPhylica plumosa<\/a> (Cape Myrtle) – good specimens at Sherman Library & Gardens<\/a>.
\nThomasia solanacea ‘Velvet Star’<\/a> (Solanum-Leafed Thomasia) – leaf much more chartreuse than website photo.
\nBouteloua gracilis, the species, and also the cultivar ‘Blonde Ambition<\/a>.’ This grass may not flower well without winter chill \/vernalization.
\nLygeum spartum<\/a>
\nWestringia fruticosa ‘Mundi,’<\/a> Australian Rosemary. A dwarf selection.
\nDianella caerulea ‘King Alfred.’<\/a> Favorite dianella of Jo O’Connell of Australian Native Plants Nursery<\/a>.
\nSolanum xanti,<\/a> a California native nightshade.<\/p>\n

Mr. Baldwin’s succinct planting instructions: Don’t overamend. Make the planting hole wider but the same depth. Plant high. Mulch.
