From Hyacinthus on Thursday 2nd of July 2026 07:21:56 PM PDT
Hyacinthus orientalis L. is native to the Eastern Mediterranean and is planted in autumn and dried off in summer. Height: 15-30 cm. Hyacinthus orientalis ssp. chionophilus Wendelbo is an alpine subspecies from Turkey. This form has been easy to grow in Northern California, in a pot kept dry in summer. It has not increased so I usually plant it with something else. It usually blooms in March. Photos by Mary Sue Ittner taken different years. The last shows the bulb on a 1 cm grid.

Photos from Rimmer de Vries of plants grown from seed (BATMAN 423) from the Gothenburg Botanic Garden started in 2007 and 2008. Batman is a city in the Southeastern Anatolia Region of Turkey and the capital of Batman Province. It lies on a plateau, 540 meters above sea level, near the confluence of the Batman River and the Tigris.

Hyacinthus orientalis ssp. orientalis is a recognized subspecies with a synonym of Hyacinthus orientalis ssp. albulus. The photo below is of a long lasting heirloom bulb in the Southern USA known as var. albulus that is probably this subspecies. This specimen was collected in Navasota, TX and is self-fertile.

Photos from Rimmer de Vries of plants grown from seed (BATMAN 014) from the Gothenburg Botanic Garden. Notice the difference in the leaves between the BATMAN collection seed examples of the two sub-species; ssp chinophilus (above) has wider flatter rather glaucous leaves and ssp orientalis has more upright green and canoe shaped leaves.

Here is a similar blue-flowered form which has grown in the Montgomery County, Maryland, USA, zone 7 garden of Jim McKenney for perhaps forty years. It's nothing to look at, but the fragrance is wonderful!

From Eustephia on Monday 29th of June 2026 05:12:31 PM PDT
Eustephia darwinii Vargas is from Peru near Cuzsco. It is a summer-growing plant, and requires a dryish winter to bloom. Height range: 5-10 ft. Photos 1-2 by Diana Chapman show plants that produce their flower stems in the fall. In the Bay Area, this plant blooms in July. Photos 3-6 were taken by Nhu Nguyen of plants grown by Uluwehi Knecht.

From Monocostus on Sunday 28th of June 2026 05:23:30 PM PDT
Monocostus uniflorus is native only to the Rio Huallaga valley (500-800 m). near Tarapoto, Peru. It produces gorgeous yellow flowers with a large labellum. It is said that the plants will survive temperatures above 50 °F (10 °C) and will continue to produce flowers year round in the perfect condition. This perfect condition is in the form of a greenhouse with constant mist and warm temperature. The plant grows to about 1.5 feet (45 cm) and is perfectly happy in a one gallon container. It also makes a good houseplant with somewhat low light requirements, although this low light prevents the plant from blooming well.

The photos below from Uluwehi Knecht and Nhu Nguyen show a well-known plant at the Strybing Arboretum/San Francisco Botanical Garden that grows in the garden's American cloud forest section. It is a huge plant that produces huge inflorescences of yellow flowers without spots. It is known on the internet by several names such as Bomarea aff. superba or according to the Neotropical Flora site, it is listed under Bomarea borjae Sodiro or Bomarea multiflora (L.f.) Mrb. However, the name B. multiflora appears to have spots.

From Sanguinaria on Thursday 25th of June 2026 05:18:05 PM PDT
Sanguinaria canadensis L. or Bloodroot is a beautiful plant with powdery blue leaves and a very clean white flower with yellow stamens. Height range: 15-25 cm. Photo 1 taken by Nhu Nguyen April 10, 2006 in the Great Smoky Mountains National Park. Photos 2-5 were taken in habitat in Minnesota.

Photos 1-3 show the root system of the plant. The photos 1-2 & 4-5 were taken by David Pilling. Photo 3 was taken by Nhu Nguyen. Photos 1 and 2 are of commercially supplied roots on a 10 mm grid; photo 4 shows a flower bud.

Photo 1 & 2 by Nhu Nguyen show seeds inside a pod that just opened and a large harvest of seeds harvested from a friend's garden, still with their elaiosomes attached. The elaiosomes are quickly found by ants and carried away along with the seeds into the ground. Photographs 2-4 by David Pilling show seed and germinating seed on a 1 mm grid in Autumn 2013. Seed was obtained from Gardens North in January 2009; it came moist packed. It is said seed should not be allowed to dry out and exposure to gibberellins from woodland soil or leaf litter are needed for germination. This seed had been kept moist and at outdoor temperatures.

From Legacy Bulbs Four on Wednesday 24th of June 2026 07:17:10 PM PDT
Eranthis hyemalis, winter aconite, is in the Ranunculaceae family, and like many members of the family is poisonous. Native to Asia Minor and Europe woodlands, it flowers in winter, usually ahead of snowdrops. Hardy in WHZ 4-7, and probably colder zones if well mulched, it may naturalize in part shade under trees and shrubs. It can be invasive where happy, and can be controlled by digging up when still green. It has naturalized in Ontario, Canada, and the United States south and east of the Great Lakes, east to North Carolina and New York.

From Lachenalia Species Four on Tuesday 23rd of June 2026 05:33:19 PM PDT
Lachenalia juncifolia Baker is found in sand or limestone outcrops in the winter rainfall Cape. It has two leaves with maroon bands and white or pink bell shaped flowers on long pedicels with exserted anthers. Height range: 7-40 cm. Don Journet describes it in his collection. "The flowers consist of outer perianth segments which have a blush tinge at their base grading to pink and finally a rose-purple tip and gibbosities. The inner segments, which are largely hidden, have the same dark rose-purple tips showing between the outer segments. The flowering season has been fairly short for me being the third week in September to the second week in October." The first photo from Rod Saunders. The rest from Mary Sue Ittner.
