In December 2004 the Pacific Bulb Society List topic of the week was favorite white flowered bulbs. Participants mentioned the bulbs listed below as favorites. They are listed alphabetically, sometimes with comments, followed by the name and the location of the person who named them as favorite, usually from experience growing them. If we have a picture of the plants mentioned on the wiki there is a link to that picture.
Allium hyalinum -- Mary Sue Ittner, Northern Calfornia
Amaryllis 'Mont Blanc' -- Doug Westfall, Southern California
Anemone blanda 'White Splendor' -- This is the major harbinger of spring for here. I have planted sheets of this across a sloped area of the garden that meets the afternoon sun. -- Jim Waddick, Kansas City, Missouri
Arisaema candidissimum -- It is the purer white forms and the green throat that gives so much quality to this plant. -- John Grimshaw , Nr Cheltenham, UK
Calochortus has to get my vote as a genus and I am unable to limit it to one species when Calochortus albus, Calochortus tolmiei, and Calochortus umbellatus are in the running along with some of those exquisitely marked Mariposas: Calochortus superbus, Calochortus venustus, Calochortus vestae and wonderfully hairy Calochortus umpaquaensis. -- Mary Sue Ittner, Northern Calfornia'. Calochortus venustus -- Dennis Kramb, Cincinnati, Ohio
Colchicum speciosum 'Album' -- It is the green throat that gives so much quality to this paragon of autumnal bulbs. -- John Grimshaw , Nr Cheltenham, UK
Crinum moorei 'Album' and Crinum × powellii 'Album' are both good. -- John Grimshaw , Nr Cheltenham, UK
Crinum 'White Queen' flowered last year for me and was awesome. -- Kevin Preuss, Florida
Crocus boryi -- a memorable spectacle was a swathe of the white flowers across the green grass of some old terraces. John Grimshaw , Nr Cheltenham, UK
Crocus goulimyi 'Mani White' I have found to be a very reliable garden plant, forming a clump and coming up with a good tuft of flowers each autumn. -- John Grimshaw , Nr Cheltenham, UK
Crocus sieberi 'Bowles White' is hard to beat, retaining its golden throat -- John Grimshaw , Nr Cheltenham, UK -- Also John Grimshaw , Nr Cheltenham, UK; Jim Waddick, Kansas City, Missouri
Cyclamen hederifolium v. albiflorum -- John Grimshaw , Nr Cheltenham, UK
Elisene -- enticing, but much more difficult for me here in Florida. -- Kevin Preuss, Florida
Erythronium californicum -- the leaves are wonderful and the flowers intricately beautiful too. -- Mary Sue Ittner, Northern California
Eucharis is a most intriguing winter bloomer. E. amazonica and E. formosa are in full bloom and wonderfully scented indoors or in the greenhouse. The petiolate foliage is an extra bonus. Kevin Preuss, Florida
Eucharis 'Christine' --. Much more compact than the regular Amazon lily and it sends up spikes of deliciously fragrant white flowers almost like clockwork every three or four months. Corey Thompson, Chicago, Illinois
Galanthus is the top of my list -- Mark Smyth, N Ireland. Also John Grimshaw , Nr Cheltenham, UK.
Galtonia candicans -- John Grimshaw , Nr Cheltenham, UK
Gladiolus callianthus -- John Grimshaw , Nr Cheltenham, UK
Hesperocallis undulata - (desert lily). I have seen it in Arizona's Death Valley along the road in April. The trumpet-shaped flower has a white interior with gray-backed petals. As beautiful as it is fragrant. --Jerry Murray - Washington, the state
Hippeastrum brasilianum, Hippeastrum parodii, Hippeastrum solandriflorum , syn. H. elegans, all are attractive -- Kevin Preuss, Florida
Hymenocallis -- Tops on my list of favorite white-flowered bulbs is this genus. I can't wait till they send up their stalks of elegant, fragrant white flowers this coming spring or summer. The one that has bloomed for me so far, Hymenocallis 'Tropical Giant', has seduced me forever. Corey Thompson, Chicago, Illinois. Regardless of taxonomic confusion, the white flowered taxa that blooms in all of the older neighborhoods on Galveston Island, Texas - Boyce Tankersley, Chicago, Illinois. This one has moved up to my #1 slot, receiving more attention than most of my collection. -- Kevin Preuss, Florida
Iris (Dutch) -- Dennis Kramb, Cincinnati, Ohio
Ismene -- enticing, but much more difficult for me here in Florida -- Kevin Preuss, Florida
Lachenalia orthopetala -- Mary Sue Ittner, Northern Calfornia
Lilium -- It seems to me that there is little to beat a white lily, and my first choice would always be Lilium candidum, whose white has a warmth I don't find in the Asian species and the most glorious scent. Then there is Lilium martagon var. album, so cool for the woodland garden, and if I didn't garden on limestone, Lilium speciosum 'Album' . John Grimshaw , Nr Cheltenham, UK
Lilium washingtonianum growing in its native Sierra Nevada habitat. The white trumpets rose a couple of feet above low shrubs and the fragrance was divine. Nancy Gilbert, Grass Valley, California
Massonia pustulata, a form with really pustulate leaves and long stamens. Mary Sue Ittner, Northern California
Moraea atropunctata -- Mary Sue Ittner, Northern California
Moraea tricolor 'Album' -- Reliably sending up masses of white flowers in mid-winter to spring. -- Boyce Tankersley, Chicago, Illinois
Narcissus -- I am particularly fond of white small cupped daffodils in Division 3, many of which have a wonderful soft green eye and throat, and a size and poise of great charm. -- John Grimshaw , Nr Cheltenham, UK ; Narcissus, I like the all white Narcissus 'Stainless' and the contrast of Narcissus 'Raspberry Rose' rich pink and white is a standout. -- Jim Waddick, Kansas City, Missouri
Narcissus alpestris -- Pride of place among the species goes to this species with lop-eared perianth segments and down-pointing trumpet, but alas, mine have all died out. -- John Grimshaw, Nr Cheltenham, UK
Narcissus cantabricus -- crystalline appearance -- John Grimshaw , Nr Cheltenham, UK
Narcissus poeticus -- red-eyed -- John Grimshaw , Nr Cheltenham, UK
Neomarica gracilis -- One of the easiest and most graceful houseplants I have ever grown. I love the elegant shape and sweet, gentle fragrance of these flowers and the winter show gets better with each passing year. Corey Thompson, Chicago, Illinois
Nerine flexuosa 'Alba' -- John Grimshaw , Nr Cheltenham, UK
Onixotis stricta -- Mary Sue Ittner, Northern California
Ornithogalum -- John Grimshaw , Nr Cheltenham, UK
Oxalis versicolor which on a warm day is such a bright statement and on a cooler day has those wonderful red markings as it is all curled up. -- Mary Sue Ittner, Northern California
Pancratium must also be lumped into these favorites for me. Kevin Preuss, Florida
Polianthus tuberosa -- The elegant white flowers, the incredible fragrance; and summer is so far away! Boyce Tankersley, Chicago, Illinois
Scadoxus puniceus 'Alba' -- Doug Westfall, Southern California
Spiloxene capensis -- Mary Sue Ittner, Northern California
Trillium grandiflorum -- John Grimshaw , Nr Cheltenham, UK
Triteleia lilacina -- It is diminutive, but it is one of those flowers that is pure magic if you take out a magnifying glass or a hand lens and peer inside. Blue anthers form a crown around hundreds of iridescent glass beads that encircle the blossom. -- Nancy Gilbert, Grass Valley, California. This Triteleia is wonderful. It is probably my favorite Triteleia. -- Mary Sue Ittner, Northern California
Tulipa 'Purissima' starts greenish cream and fades to ivory white, its massive flowers lasting for weeks if the weather is kind; Tulipa 'White Triumphator' looks fabulous in the borders. -- John Grimshaw , Nr Cheltenham, UK
Zantedeschia aethiopica, growing in immense numbers at the foot of the Sani Pass about now, or in Cape Town a few months earlier: no doubt about its whiteness! John Grimshaw , Nr Cheltenham, UK. I've never been successful with the colored flowered species but the white flowered species is incredible - as well as fragrant. Boyce Tankersley, Chicago, Illinois
Zephyranthes candida -- is hard to beat with masses of bloom that goes on for months. -- Mary Sue Ittner, Northern California. Also Dennis Kramb, Cincinnati, Ohio
Zephyranthes drummondii -- I grew up with this geophytic taxa on a ranch in southwestern Texas and it still brings back favorite memories as well as a nice fragrance. --Boyce Tankersley, Chicago, Illinois
