Gardeners' Notes:


On Mar 4, 2012, Vestia from San Francisco, CA wrote:

This should properly be referred to as Hoya carnosa 'Hummel's Compacta' as Ed Hummel produced it; later Cobia renamed and trademarked it with 'Krinkle Kurl'. Even though there is a publication of this cultivar as the species H. compacta, it is not a natural species and has never been found in a wild habitat. Whatever you call it, it's a contorted carnosa. Easy to please, but slow to flower, it is a plant every Hoya enthusiast should find a spot for in their collection.

I just received one of these plants after my aunt died. On the description card it reads my Grandmothers name and the day that she started it from seed. 1896!!!! I know nothing of this plant and to me it looks sickly. Very white and droopy! Any thoughts on how to bring it back and suggestions for keeping it strong? I live in NorthWestern Wisconsin!

My original plant came from my great grandma about 1913 in upstate New York. There are 54 known cuttings of this plant in my family all over the states. One here in San Diego is on a trussell and covers about 6ft in height by 8ft wide. It flowers all the time. If you move the plant it will stop growing for up to 3 or 4 months. We keep ours outdoors year round. Keep it moist and give it alittle plant food twice a year. Ive never planted one in the ground, always in a pot. I love mine, its become a family hair loom.

My mom gave me a started off of this plant. It was my great grandmas. I have it in my windowsill in my kitchen. It's doing good, but I think it need a little more sunlight. I have it in a small pot and it likes to be root bound. I can't wait to see it grow and hopefully produce flowers.

Just purchased this plant at a home improvement store in Tulsa last week. I've had this plant before, many years ago, when some nice lady gave me a few cuttings of it. The plant I just bought has 12 individual plants; about 7 of them are probably a foot long and the rest are shorter. One of them has solid white leaves on the growing half (hanging end) of one plant. There was also a single solid yellow curled leaf that I am trying to "save" and hopefully get to root. This plant has some variegated areas too, although most are solid. I am absolutely THRILLED to learn that it may even produce some orchid-like flowers and actually have a fragrance! What kind of fragrance might that be? Unfortunately, I just repotted it, so I will either have to reconsider that effort or just bide my ti... read more

I've had this plant for 25 years, it bloomed only once. I started it from one leaf! What do I feed it, should I transplant? It's 5 feet lond and quite full.
Living in N.Y. State, I keep the plant inside all winter and put out in the spring.
Thanks for some advise!

We were given this plant about 6 years ago by my husbands grandmother. She had it for about 20-30 yrs. It's foliage was very nice, so we took it in as a houseplant only. It has been in my garden window for about a year. Never in all the years with granny or ourselves, until now, has it done anything so wonderful! I quickly started researching to find out just what this plant was, since granny only called it by elephant ear. We knew this was not true since we grow elephant ears in the summer in our garden. I called on a person of vast plant knowledge, my step dad Frankie Soukal. He's been in the biz forever. I described it over the phone and he said "Hoya". I jumped on the web and he was right. WE DO NOTHING to this plant. I recently gave it a good soak and a leaf bath in the sink, but tha... read more

I am not much of a gardener, and don't know much about many plants other than Hoyas and Philodendrons. The latter loves to live in my bathroom because it is humid and I am forced to water it at least once a week during deep cleaning of the bathroom. But the Hoya...this is my favorite. I have two varieties now, a rope hoya and the other I have not figured out the proper name, but it's the common hoya that my mother grew when I was a child (which she still has by the way...it was passed on to her from her grandmother). Only this one has varigated leaves so I am anxious to see the bloom color! I have found (because mother always told me and mother never lies!) that Hoyas love to be compact in their surroundings (root bound), like to be a little neglected between waterings, love the early... read more

Since I live in a cold climate(Wisconsin) I have my rope plant indoors. It is at least 15 years old and grew very little in a hanging basket in my kitchen. When we moved into different home 6 years ago I repotted and placed on window ledge with southern exposure. Now it is thriving and for the first time it has flowered!

In June, 2004, I received 3 Hoya plants, and instructions to plant them in a soil medium of half potting soil and half Perlite. The plants are small, and I placed all of them in a medium sized hanging pot. Since I live in central Florida, and they like heat and humidity, I hung my plants in my open carport. I was told to water when the soil was dry half way to the bottom of the pot. The plants get the first two hours of sunlight and are doing great! I have a "sun room" I will place them in when the season turns cooler. I can not wait to see them bloom. From pictures I have seen, the blooms are very unusual, looking like a honeycomb from a bees hive.

Found this in a forgotten corner of my favorite nursery. The proprietor was shocked to see how much it had grown and that it was blooming! He hadn't even priced it yet so he just gave it me!

I'm debating on whether or not to put it outside. It's tropical here in MS but I'm worried that I will have a pest problem due to the nectar. Right now it's in a tiered hanging basket in my kitchen window and seems happy!

I purchased this Hoya Compacta about 5 years ago and have never been able to get it to bloom for me. It was a very small plant when I purchased it. I just recently repotted the plant, taking it out of it's original pot and replaced with fresh soil.

Easy to care for hanging basket plant with curly leaves that give it a distinctive look. Flowers, like on most Hoyas, are absolutely beautiful, fragrant and rich in nectar. Nectar sometimes is dripping from flowers and can create a bit of a mess below. Location for plant should be bright and a little direct sunlight will not hurt. Slower growing then the “normal” and variegated Carnosa form.
Mealy bugs may attack the plant and are difficult to spot since they like to lodge near the base of the leaf, which may be covered from direct view. Direct application of rubbing alcohol with a cotton swap for light infestations or spray with water, soap and rubbing alcohol mix for heavier infestations usually do the trick on those pesky critters.
Soil should never be allowed to completel... read more
