That's my attitude exactly! Thank you!

I don't like to toss in more confusion, but there's also the carnosa rubra that is NOT variegated. It's one of my old favorites...

Denise in Omaha

Why isn't an unvariegated Hoya rubra just a Hoya carnosa? Now my head hurts...:-)

Because, if rubra is a hybrid (cross between two different carnosas), then, like many variegated carnosa hybrids, it has the ability to revert back to all green.

Even if it was just a plain jane carnosa that suddenly started throwing variegations, and cuttings were made to create a "new" plant, whoever took the cuttings to develop the "new" plant, could name it, if they wanted.

Hoya australis 'Lisa' is a variegated form of australis ssp. teniupes (if I correctly recall), and I do believe it is a normal variant, and not hybridized.

I really don't understand naming an already named plant. Hybrids, yes. Cuttings of a plant that is already named, but just started throwing out curled leaves or variegated leaves/splash leaves/albomarginated leaves? Nope, don't understand. I have always been of the mindset, "Name it once and add proper subtitles". Meaning, instead Hoya of carnosa 'Rubra' (or Krimson Princess or Strawberries and cream) , it would be Hoya carnosa variegated. Instead of Hoya carnosa Crimson Queen (or Superba and whatever else they come up with), it should be Hoya carnosa albomarginated.

Instead of australis 'Lisa', it would be Hoya caustralis ssp. tenuipes variegated.

Exceptions to this rule would be true hybrids. Like Hoya compacta X Hoya carnosa. Or Hoya australis ssp. tenuipes X Hoya australis ssp. Australis. Or Hoya wibergiae X Hoya erythrina (one of these days, I WILL get a seedpod from crossing those two!).

But, that is just me.

I dunno---I've seen lots of H. rubras that reverted to all green and Denise's picture does NOT look like any of them...in fact, except for the obviously carnosa type flowers, I wouldn't know what it was....and where do they get off calling something Hoya rubra when there's no "rubra" anywhere about it? Unless they're describing the pinkish flowers?

I do like your idea of just calling those multicolored ones Hoya carnosa variegata and H. carnosa albomarginata....that's all you need--the name is descriptive and useful....stop there....

Wanted to add that many years ago I bought a "hairy" carnosa cutting from David Liddle....it was simply labelled H. carnosa, but with a separate IML # which, of course, I've lost (sigh)...the point is--although the plant is faintly fuzzy all over, no one felt the need to add a descriptor to it---it was just one variant of a highly variable species....someday I hope someone takes the whole carnosa/pubicalyx species in hand and uses DNA to figure out what's going on...I'm going to guess that there are very few legitimate subspecies, and that things are a lot simpler than they seem...hopefully....

Denise that is beautiful. I just saw a rubra at Lowes. It was the biggest one I have ever seen! But their plants are always full of mealy bugs. I told them months ago but I don't think they care

So does that mean that Hoya carnosa rubra and Hoya carnosa Brazil are the same plant??? They look similar just not sure if they are the same plant with different names.

Hoya carnosa cv. Brazil, as I understand it, is a cross of carnosa rubra/krimson princess/whatever and either compacta or cv. Chelsea.

11,926 Int. Cl. A01h 5/00 US. Cl. Plt.88 1 Claim ABSTRACT OF THE
DISCLOSURE A new and distinct plant variety of the milkweed family
resembles plants of the Hoya carnosa Exotica variety in variegated leaf
patterns but is distinguished from the latter variety by certain color
characteristics, by slightly larger stems and by a somewhat wider leaf
blade that is usually ovate in shape.

The invention relates to a new and distinct plant variety of the
milkweed (Asclepiadaceae) family and which has been named the Hoya
camosa (CV) Rubra by the inventor.

Certain plants of the milkweed family are well known in the foliage
plant market and among these are those of the Hoya carnosa Exotica
variety and of the Hoyw carnosa Variegata variety. A lesser known
related variety found in the foliage plant market but which is rapidly
gaining popularity is the Hoya carnosa Tricolor variety.

Plants of the Hoya carnosa Tricolor variety have variegated leaf
blades which are similar in pattern to those of the Hoya carnosa
Variegated variety but are preferred by comparing purchasers in the
market place because of certain characteristic colors which, in immature
and newly matured growth, appear in the albino or variegated areas of
the leaf blades.

Plants of the Hoya carnosa Exotica variety have variegated leaf
blades but in contrast to the albino leaf blade border areas of the Hoya
carnosa Variegated plant variety are characterized by an albino center
field in the leaf blade. The main object of the invention has been to
develop a plant variety which is related in general appearance to the
Hoya carnosa Exotica plant variety but which exhibits colors in the
albino leaf blade areas that are similar to those found in the Hoya ca
rn0sa Tricolor variety. The object of the invention has been fully
realized as will be evident from the following detailed disclosure.

Plants of the new variety generally resemble plants of the Hoya
carnosa Exotica variety and are not only related to this variety but
also related to the Hoya CLH'VIO'SLZ Variegata and Hoya carnosw Tricolor
varieties. The new variety is mainly distinguished from its antecedents
and related varieties known to the inventor by a combination of certain
color and structural characteristics which will be apparent
subsequently. The new variety appeared as a sport on a plant of the H
oya carnosa Tricolor variety which was under cultivation in a nursery at
Winter Garden, Fla, and since the initial discovery of the new variety,
has been asexually reproduced by the inventor at the Winter Garden
nursery by the propagation of stem cuttings taken from the original
plant.

Through successive propagations, it has been ascertained that plants
of the new variety generally resemble plants of the Hoya carnOsa
Exotica variety but are distinguishable from this plant variety and from
other related varieties known to the inventor by a growth habit which
combines the following characteristics:

(1) Larger diameter stems than those of the Hoya carnosa Exotica
variety and which in color are dominated by purple, purplish red, red,
reddish brown and/or pink hues prior to becoming glaucous;

Plant Pat.

"ice" (2) Leaves with petioles that in color are dominated by purple,
purplish red, red, reddish brown, pink and/ or yellowish pink hues
prior to becoming glaucous, and with leaf blades that are somewhat
broader than those of the H oya carnosa Exotica variety, that are
variegated in patterns characteristic of the Hoya carnosa Exotica
variety, that have an albino center area which in color is dominated
during early immaturity by purplish pink, purplish red, red and/or
yellowish pink hues, and that have a green border area which is overcast
during early immaturity with color endowing the border area to the
ordinary eye with a blackish and/or brownish appearance; and

(3) An inflorescence that has a peduncle color dominated by purplish
red, red and/or reddish brown hues prior to becoming glaucous, a
pedicel color dominated by purplish red and/ or red hues, a sepal color
dominated by purplish red, red and/or reddish brown hues, and a petal
which in color at its upper epidermal side is dominated by purplish pink
and/ or pink hues and which in color at its lower epidermal side is
dominated by a purplish red hue.

The accompanying drawings serve, by color photographic means, to illustrate the new variety and wherein:

FIG. 1 is a color photograph of a plant specimen of the new variety and shows the upper epidermal sides of the leaves;

FIG. 2 is a color photograph of the specimen seen in FIG. 1 and shows the lower epidermal sides of the leaves;

FIG. 3 is a color photograph of an inflorescence of the new variety; and

FIG. 4 is another color photograph of the inflorescence seen in FIG. 3.

The following is a detailed description of the new plant variety
with colors and hues, unless otherwise clearly indicated by the text,
being named in accord with the ISCC- NBS method of designating colors
(US. Department of Commerce, National Bureau of Standards, Circular 553,
issued Nov. 1, 1955), the named colors being interpreted from color
notations derived by comparison with the color specimens in the current
Neighboring Hues Edition of the Munsell Book of Color, published by the
Munsell Color Company, Inc., of Baltimore, Maryland.
