Welcome, home gardeners!

Because Golden State Bulb growers is a breeder and commercial producer of its own unique genetic lines, we do not sell them directly to the general public.  However, we hope that you will learn about our branded products and look for them in your favorite kindergarten or through the company by mail.  We have compiled a list of shipping sources with our bulbs to help you find our product.


We are sure that you will enjoy the best flowering and improved plant habits of both callafornia Callas® and amerihybrid ® begonias, whether they are in your garden, in a patio container or as decorations in a vase.


Below we have given some botanical and historical information about calla lilies and begonias.  We hope it will be interesting. Zantedeschia aestivae, a summer-flowering hybrid of colorful Callas, has long been one of the two main specialties of Golden State bulb growers. 


Our fourth generation company, located on the central coast of California, has been engaged in the selection and breeding of four different types of colorful Kalia lilies for more than eighty years.  We have now introduced more than 40 new unique hybrid varieties under the callafornia Callas®brand.  Now, fortunately for all of us, there is a choice of varieties such as: bright pink Neon Amour and Garnet glow; yellow-red flame and flame; pure white, turning into pink with age Crystal blush; mint Julip from Ivory; strong Ruby Rose; Lavender stone and amethyst; intriguingly variable (related to light and temperature) pink-lavender shades of lipstick and super jewel; two-color, such as peach-apricot-peach chiffon and pink-red, such as pillow talk and parfait; and bold yellow with large flowers, such as a golden chalice.  There are others that are currently being introduced at a rate of at least two per year.  The latest versions of callafornia calla ® include a solid erect gold rush and a spectacular bright yellow sunburst with speckled leaves.


Calla is zantedeshia.  Although they are called" calla lilies", they are not lilies in any botanical sense.  But they still have calla.  In fact, the genus Zantedeschia (with eight species) belongs to the arum family... a family with such diverse representatives as anthurium, jack on the pulpit, dieffenbachia, philodendron, caladium and tarot. 


The main distinguishing feature of all arums is that their inflorescence or "flower" is actually not a flower at all.  Instead, it is a large fleshy modified leaf or strip.  True flowers are multiple, with infinitesimally small male flowers covering the top and larger female flowers covering the lower part of the vertical, finger-shaped blade stalk, which is centered in the middle of the blade.  However, even here these pure white, yellow, pale and dark pink modified leaves or stems of this species will always be seen as "flowers" and are always intended for "Lilies".  It is an appropriate elegant name with a certain large-scale and stylish association.   So, who can complain? The real advantage of this physiology is that the Kalia lilies "bloom", have a unique and quite sensual shape, and are also durable and long-lasting in the vase.  They can be transported dry for a day or more, but will be moistened in the composition and, with a floral preservative (or mouthwash) in water, will last in the vase up to 14 days.  Inflorescences in some varieties even continue to change color after cutting, especially in low night temperatures.  In short, these are excellent cut flowers.  Trim the stems and change the water every two days.  A single flowering lasts, depending on the temperature, up to four weeks on the plant, and flowering will spread over several weeks for colorful miniature species and will last 14 weeks or more for aethiopica species.


When considering buying calla lilies for pots or landscaping, including water gardening, you should first think of two main groups: Zantedeschia aestivae ("miniature" colorful species) and large white (mainly) Zantedeschia aethiopica.  These two distinct groups can be identified on the basis of their different natural history and habitat preferences.  Although descriptive botanical information is of interest to Botany students, what you really need to know about plant care and culture starts with its natural history.


NATURAL HISTORY-CALLAS


The two main divergent groups of zantedeshia, identified by their different natural histories, are the colorful miniatures and zantedeshia ethiopica.  Miniatures consist of usually spring-summer flowering, colorful and shorter species, some of which have translucent spots on the leaves.  They have developed in sunny places, such as the sandy slopes of the South African Transvaal or other similar regions with freely drained soils that are not excessively moist and where the ground does not freeze.


The second main group, Zantedeschia aethiopicas, is more evergreen and tends to bloom in the cold season.  They are taller (with the exception of one dwarf) and mostly white (with the exception of one toned pink and one spotted green-white) and are known as Zantedeschia aethiopicas.  They have evolved and are therefore giving way to much more organic soils with much higher moisture levels and often less light.  Their natural habitat is the creeks and banks of streams.


"Miniatures", the color types now known scientifically as Z. aestivae.


The miniature colored Kalia lilies, which bloom outdoors in late spring or early summer, still have selected pure species represented in commercially available varieties.  All these colorful calla lilies are more deciduous than Ethiopians.  The leaves of spring-flowering species die off at the end of summer, only to grow again in spring when the soil temperature, depending on the species, reaches between 50 ° and 65 ° F (10 ° to 18 ° C).  They are not hardy and must be grown and stored in regions where the ground freezes.  Species Z. or maculata-leaf spotty (creamy) white; Z. rehmannii superba-plain pink with immaculate green leaves; Z. elliotiana ? golden yellow with spotted heart - shaped leaves; Z. rehmannii violacea-from lavender to dark pink and immaculate green lanceolate leaves; Z. pentlandii-large yellow with variable spots on gray-green leaves; all types are available for the home gardener.  But the most interesting are the hybrid hybrids between them, which gave the whole range of Callafornia Calla® flowers with improved flowering and plant habits.


Breeding a new F1 hybrid is a process that requires a lot of patience... From the moment of transition to the first appearance of flowers, more than two years pass.  Thus, it takes ten years for our classic breeding efforts to bring a new variety to the market.  However, it is worth spending time on this-thanks to these efforts, the whole horticultural world will be enriched.


The large-scale production of colorful potted calla lilies is a recent phenomenon.  The genetics of callafornia Calla ® is at the forefront. Numerous blooms in small pots and containers in the courtyard are largely due to our breeding efforts.



 ZANTEDESCHIA AETHIOPICA


Ethiopians prefer cool (45-65 ° f / 7-18 ° C) temperatures and are available as dormant rhizomes in autumn (currently you can find three, and sometimes four varieties).  As container plants are available from winter to spring.  Plants can be two to five feet tall (5 to 1.5 meters) with dark green heart-shaped leaves that usually have no spots.  They live in more humid and shaded conditions than "miniature" species or more compact and usually colored.  These trees are not immune, and the leaves will suffer from frost.  Their rhizome root tubers do not survive deep freezing of the soil.  (Hence zones 8 and 9 with mulching for outdoor use.)
