Sacramento Garden Notes JANUARY 2012 difficult seeds MUCH easier, even for a small breeder. Written & Published by Robert B.

Hamm How Hybridizers and Technology have changed the plant world for gardeners: I thought a good start for the new year would be some thoughts about changes in the gardening world in recent decades. When I was in college and working in the Orchid Greenhouse, the above plant would have been extrodinary, not only did the color combo not exist, but even if it did, the cost would have been astronomical since back then division of mature plants (which is slow) was the main way to propagate Orchids meaning high prices. Today, with tissue culture technology, even a newer variety can be turned out by the thousands, and I found this at Home Depot for $21 dollars. A fraction of the cost something like it would have brought just 20 years ago. Even hybridizing orchids is easier now with technology making growing what were very Above is a Cuphea hybrid, an example of hybridizers taking a small, rarely seen group of plants and using species discovered in our ever shrinking tropical habitats and creating dozens of forms now seen in nurseries. In the past, only the common blue Cuphea was seen, now it comes in a wide range of colors and forms. Our increasing techology, which makes traveling around the world an everyday affair, has allowed collecting expeditions to areas formerly never or rarely visited, which has brought a wealth of new species into cultivation. Not only can more places be reached, but getting live plant material back in now a matter of hours or days, compared to weeks or months back in the days before regular global supersonic air routes. This has drastically increased getting LIVE specimens back to where they can be propagated and distributed. These new species allow an increasing base for future hybridizers to develop new varieties and forms. Plus a rich source of research for new drugs and medicines and even food sources. An example of how collecting has become easier with even plant club members taking part, is The American Begonia Society which has financed several expeditions to collect new and/or endangered species to help save them before habitat destruction can send them into extinction. An example is B. luzonesis shown on the next page. Although this plant needs tropical rain forest conditions so is generally a terrarium or greenhouse plant, it offers a new genetic inheritance for future breeding efforts to develop new and exciting hybrids for everyday plant growers. Dec 4th First Ipheon blooms on all 3 varieties. Put down Azalea cuttings after took all the flower buds off. Put them in part shade and will keep moist. Species glads are up and growing, will be interesting to see when they bloom now that have been in our climate a growth season and are acclimated. Above: B. luzonesis, photo taken from The American Begonia Society virtual greenhouse at their website: http://www.begonias.org/ Above, a pot of Daffodil Rijnveld‟s Early Sensation from Spring 2011. The first year planted, these will bloom late, around the time of other Daffodils but from the second year on will be the FIRST daffodil in bloom, often at or before Christmas. Dec 8th - Centranthus (Jupiters Beard) is still in bloom next door, as is nutmeg scented geranium (Pelargonium species). Cleaned and trimmed neighbors front bed in exchange for cuttings / plants. A few of the changes I‟ve seen in the last 40 years include MANY new colors in different varieties of plants. Examples that didn‟t exist before include red flowered Vinca, Impatiens in 18 colors rather than just 5 or 6, MANY new colors in Orchids, white Marigolds, Echinaceas in colors other than purple and white, newer, faster blooming perennials and many many others. Plant Diary: I‟m resuming garden observations so you have some idea of what is growing/blooming when, even if your location is a bit later than the warmer Curtis Park Area. I hope it helps you. Dec 1st Daffodil Rijnveld‟s Early is showing growth, this early Daffodil normally starts blooming for Christmas once established. Centranthus ruber above photo by Robert B. Hamm The cold weather is getting to the Coleus and Impatiens, though haven‟t actually frosted yet. Both are looking a bit worn. I‟m leaving them to see what happens with this warmer microclimate. The fall blooming crocus are finishing up, while the first of the early species crocus have broken ground. Put down seed for a new tuberous begonia strain, lobelia „Queen Victoria and a few others. Dec 12th – was over at neighbors yesterday and the following were still blooming: Pineapple Sage, one of the bushy Erysium(starting again after a summer lull), a dark purple penstemon, pink guara and a late bloom spike on a lycorus. The sedums have barely finished dying back and are already showing new growth. One of the winter blooming Red Hot Polkers is budding also. I put down over 200 more pots of cuttings/ divisions/seed, which should bring me up near 3,000 pots. Many of the Sedums start putting up growth buds at the base of the stems very early in the year. This is normal and not something to worry about. They are very freeze hardy. Dec 13th – the first of the Rijnveld‟s Early Sensation Daffodils in a 15 gal. container is opening, with lots of buds coming along. I planted the bulbs in the container last year, to enjoy, then as they died back in late spring I used the containers for Tomatoes this past summer. By the time the Tomatoes were done this fall, the bulbs were just about breaking ground. Nice dual use. Freesia and species Tulips are in another 15 gallon used the same way. Above Lobelia Deep Red, which I divided up for 4” and gallon pots. December 14th – running low on gallon containers. The first Daffodil is open. January Garden Notes: January is a month for a number of garden chores and a few warnings: a) Pruning of roses and many shrubs and trees, however check the notes on what NOT to prune in the last issue (Dec 11) so you don‟t cut off the blooms of early bloomers. There are a number of free pruning classes this month, check the Home & Garden calendar section of the saturday Sacramento Bee (can be checked online at Sacbee.com) or with your local nursery. b) Bareroot and Dormant plant material is coming into local nurseries this month and it is a good time to get many items into the ground and save a bit on them over potted plants later. HOWEVER some warnings are in order.. bareroot material should not be dried out or sprouting into early growth.. a major problem with packaged material in many box store retailers. Get in and get your material EARLY for best selection and quality. c) Weather I have bareroot or not this spring will depend on finances but please note that any bareroot I have at sales is FRESHLY received for each sale, unlike at many nurseries. d) Certain summer bulbs are received early in nurseries but HATE chill, never mind cold.. so if your getting the following either plant indoors, in a greenhouse or hold off till the weather is warmer: Caladiums (need WARMTH or will just rot), colored tropical Callas ( not quite as sensative but want warmth) and Dahlias which are often hardy here, but if you put new tubers out too early you risk them rotting before they sprout. For Dahlia tubers, I‟d suggest potting them into gallon containers in a sunny spot until they are up and growing. The pots absorb heat faster than the ground. e) If you or a friend have a fireplace, wood ashes spread across the garden during the winter are a good source of potassium and phosphorus plus trace elements. This is one reason that many plants grow so well after a fire, the ashes are rich in nutrients. Viola hederacea or “Australian Violet” blooms almost year round and is a multi purpose plant. This runner can be used as a groundcover, in a hanging basket, or trailing over the side of a container. Prefers sun to part shade with regular water and will tolerate a large range of soil types. I think this would make a good lawn substitute under planted with bulbs for variety and color. Above and below pictures are of the lights in the kitchen I am using to start seeds and cuttings. As you can see, the plants are kept close to the lights. I am using one full spectrum and one cool white tube in each fixture. Observations continued from page 3 Dec 20– put down over 200 cuttings of different things today. Mostly perennials that stay evergreen. The winter blooming Red Hot Polker is budded, the winter blooming Salvias are in bloom and while many colder outer areas have had repeated frosts, few signs of in around my yard or at Cynthias, although the impatiens and coleus are reacting to the cold and looking tatered. One Johnny Jump Up struggled through the summer in part shade and now dozens of seedlings are growing in that bed, should make a bright spring patch of them. Thank you, we did it again! – Thanks to many of you, Sunburst again this year covered not only all of their child clients, but referrals from CARES, US Davis pediatrics, RX staffing and others in the area! So again, Thank you on behalf of all the staff and clients at Sunburst Projects. Above, Euphorbia „Ascot Rainbow‟ – another newer introduction (2010) that stays compact without bare stems. Sun and well drained soil are the requirements. Many of you asked about this when you saw it at Davids house in Natomas. I have have some available. Supporters Discount 2012 – to Thank all The above Pelargonium (commonly called Geranium) variety is colorful even without the flowers with the red centered gold foliage. The flower is actually a bit pinker than shown but pinks can be hard to photograph, showing up either more red or purple than they really are. This picture was taken on Dec 21st. Pots from small to gallons are needed as well as flats! who sent in donations to help with the newsletter, soil costs, seed costs and other expences, I will have a printout of donators at all sales and you will receive the following discount on EVERY plant purchased in 2012, in addition to special “First Choice” invites: 4” or smaller pot – 50 cents off 4 ½ to 2 gallon pots - $1.00 off Larger than 2 gallon - $2.00 off This is easier than a percentage, as we don‟t need to worry about small change and odd amounts.
