[ Dahlia 'Bloomquist Tamara' | Posted on January 16, 2022 ]

Flower form for Bloomquist Tamara. Dahlia World gives the form as fimbriated. [Bloomquist Tamara M.Fim. R. 2009 bloomquist USA ads12]

My limited photo evidence of the blooms suggests that the petal tips are not significantly split or serrated, but the petals are very narrow, curled or twisted, and revolute through most, if not all, of their length. To my inexpert eye, the blooms appear more like a cactus type than anything else. I offer this observation with the caveat that dahlia blooms do not always behave true to their cultivar standards, either in form or color. The blooms I've seen might be anomalous.

[ Dahlia 'Mr Optimist' | Posted on January 11, 2022 ]

The earliest blooms on the plants I saw at Dahlia Hill were not fully double, as they should have been for an 'informal decorative' designation. This caused me to doubt the plant label. However, blooms that were produced later in the same season did conform to the official description. I mention this as an aid to gardeners who might wonder whether they were sold the correct tubers when they see the first blooms on their plants.

[ Dahlia 'Ebony Star' | Posted on January 10, 2022 ]

Dahlias with flower forms, like Ebony Star, that are classed as novelty (NO or NX) typically aren't given size descriptors such as M, B, BB, etc. The blooms I've seen are about the size of a typical single form dahlia, i.e. about 4 inches across, somewhere between M and BB.

[ Dahlia 'China Doll' | Posted on January 7, 2022 ]

Disambiguation notice: The probable reason that two flower forms (single and waterlily) are listed for this cultivar is that, according to Dahlia World's list, there are two dahlias of this name.

One of them is a red single (China Doll I Sing R. 1990 takeuchi USA adsc02)

The other, which most closely matches the photo in the database is a waterlily (China Doll II SWL Pk.-Y.Bls <1994 swan island USA ads05).

I note, also, that this second form is a better match for photos I have taken at Dahlia Hill for a cultivar labeled 'China Doll', but which I have not yet uploaded to the database. They are a blend of pink and yellow, but are considerably darker overall than the photo currently on file, which is purportedly from the developer, Swan Island.

[ Anglojap Yew (Taxus 'Beanpole') | Posted on May 10, 2021 ]

This cultivar belongs to the group of hybrids that are crosses between English yew (Taxus baccata) and Japanese yew (Taxus cuspidata)

[ White Fir (Abies concolor 'King’s Gap') | Posted on May 5, 2021 ]

The American Conifer Society says this cultivar derives from a witches broom that was found in Pennsylvania by Gregg Gulden in the late 1990s.

[ Japanese Garden Juniper (Juniperus procumbens 'Kishiogima') | Posted on May 3, 2021 ]

The American Conifer Society describes the origin of the cultivar as being a color sport of the species, which was found in Japan in the late 1990s.

[ Orchid (Paphiopedilum Aladin) | Posted on February 27, 2021 ]

Disambiguation notice. There are two very similarly named Paphiopedilum grexes of different parentage, one described on this page (#1 below) and one which, though more recent, is not yet in the database (#2 below)
#1 Paphiopedilum Aladin (1936), Atlantis x Paphiopedilum delenatii
#2 Paphiopedilum Aladdin (2013), Hamana Samson x Hagrid
Because "Aladin" would be considered by many people to be a misspelling of "Aladdin", the possibility exists of specimens of P. Aladin having their labels inadvertently "corrected" to read P. Aladdin.

[ Rhopalocarpus lucidus | Posted on February 24, 2021 ]

Trees of the genus Rhopalocarpus are endemic to Madagascar. Virtually nothing about the life cycle of Rhopalocarpus lucidus (deciduous vs. evergreen, flowers, fruits, etc.) is available online. It is said to have a forest habitat, to be widespread in Madagascar, and to be threatened by harvesting for firewood, rope and tool making. The genus name is from the Greek, meaning "club fruit", in reference to its shape.

[ Orchid (Oncidesa Sweet Ears) | Posted on February 19, 2021 ]

Parentage, as listed by Orchid Roots, is Oncidesa Sweet Sugar × Gomesa Cloud Ears.

[ Orchid (Aliceara Winter Wonderland) | Posted on February 17, 2021 ]

Orchid Roots gives the parentage of this grex as "Bratonia Cartagena × Oncidium Gledhow". Online references sometimes refer to it as Winter Wonderland 'White Fairy', and I have seen a specimen of it labeled this way at Matthaei Botanical Gardens. To my inexpert eye, blooms labeled simply Winter Wonderland, and those labeled Winter Wonderland 'White Fairy' look indistinguishable.

[ Orchid (Aranda) | Posted on February 6, 2021 ]

Aranda is a man-made inter-generic hybrid, or nothogenus created by crosses between the orchid genera Arachnis and Vanda.

[ Peony (Paeonia lactiflora 'Red Goddess') | Posted on February 5, 2021 ]

This comment refers only to a specific location, namely the Peony Garden at Nichols Arboretum. At the request of a site administrator I am copying a comment I left for photos taken of 'Red Goddess' at that site.
"A note to anyone who might be hoping to see this cultivar at the Peony Garden at Nichols Arboretum. It is no longer in the collection, sadly. The sites it occupied nominally in Bed 12 (12-4ab) are now occupied by a new addition to the collection, Instituteur Doriat (planted fall 2018, and yet to bloom). I only saw Red Goddess bloom there (Bed 12) one year, and then the plants either stopped blooming or died out. - Elizabeth"

[ Peony (Paeonia lactiflora 'Best Man') | Posted on February 5, 2021 ]

It has been suggested that I add the following info for this cultivar, which I posted to specific photos, here in the plant comments. Please note that it refers only to a specific location, namely the Peony Garden at Nichols arboretum, Ann Arbor.
"Just a friendly heads up. This is really a message to anyone who might be hoping to view this cultivar in the Peony Garden in Ann Arbor. Based on my own extensive study of the current collection, both in person and via the bed maps provided annually for the period 2015-2019, this cultivar, Best Man, is no longer in the collection, and hasn't been in it since some time before 2015. There has been an extensive reworking of parts of the collection beginning after the 2014 growing season, and it is still underway. It may be that the plants of Best Man were lost at that time, or they may have succumbed to disease. There's no entry for Best Man in the MBGNA database (which doesn't necessarily mean it was never in the collection, since the database is notorious out of date). - Elizabeth"

[ Dahlia (Dahlia pinnata Dahlightful® Crushed Crimson) | Posted on January 26, 2021 ]

I have read that members of this series of dahlias are meant to be grown as annuals, and they are listed as such by some growers.
One site claims they were bred not to produce tubers.

[ Multiflora Spreading/Trailing Petunia (Petunia Evening Scentsation™) | Posted on January 14, 2021 ]

Some sources indicate this cultivar is a Petunia x atkinsiana
For example, https://parkseed.com/evening-s...

[ Mickey Mouse Plant (Ochna multiflora) | Posted on December 30, 2020 ]

The yellow blooms of this plant drop their petals fairly quickly. The remaining red sepals, which clasp the developing fruit can be mistaken for buds. The sepals enlarge, open out, and become brighter red as the fruit develops further, and can be mistaken for flower petals.

[ Euphorbia (Euphorbia heteropodum var. heteropodum) | Posted on December 6, 2020 ]

Note that although Catalogue of Life gives Euphorbia guentheri as the now accepted name for Monadenium guentheri, the plant described on this page, which once was called Monadenium guentheri var. mammilare, has been reclassified not as Euphorbia guentheri var. mammilare, as one might expect, but with a different specific epithet from 'guentheri', namely 'heteropodum', as well as a different variant epithet.

[ Haworthia (Haworthiopsis reinwardtii) | Posted on December 3, 2020 ]

A word of warning, or assistance, if you're trying to find database pages for variants or forms of what used to be called Haworthia reinwardtii. In 2013, when the new genus Haworthiopsis was created from a subset of Haworthia species, the mother species Haworthia reinwardtii became Haworthiopsis reinwardtii, BUT only some of its variants were similarly reclassified as Haworthiopsis reinwardtii. Other variants were subsumed into the genus Haworthiopsis coarctata, sometimes, but not always, keeping the variant-specific name. An example is Haworthia reinwardtii var. adelaidensis becoming Haworthiopsis coarctata var. adelaidensis, but Haworthia reinwardtii f. olivacea becoming Haworthiopsis reinwardtii f. olivacea.

This is but a small sample of the confusing renaming/reclassification that has recently taken place among species that used to be in the Haworthia genus. The point of this comment is to alert people who are trying to find database pages for some form or variant of what once was called Haworthia reinwardtii that they should now, at a minimum, look at all the entries both for Haworthiopsis reinwardtii and Haworthiopsis coarctata. Be warned, also, that the database entries don't have complete lists of all the taxonomic synonyms attached to a given accepted binomial, so searching the database won't always produce the desired 'hit', whereas viewing the lists of all entries under the mother species names might help you find what you're looking for.

[ Zombie Palm (Zombia antillarum) | Posted on December 2, 2020 ]

Zombia antillarum is the sole species in the genus Zombia. The genus is placed in the family Arecaceae, the palm family.
The species is endemic to the island of Hispaniola in the Greater Antilles. It is a dry land palm that is tolerant of drought.
