Hoya sp. Ko Chang Island is blooming on many peduncles

This hoya is both fun and glamorous at the same time. The many-freckled leaves make it attractive day after day and the super fragrant blooms add to the fun many times over. I have grown this one inside under artificial lighting as well as outside under Florida sunshine and humidity and it has yet to miss a beat.

Today the sweet fragrance of lilacs fills my lanai and I notice this plant may be the culprit. Although only 2 of the umbrels are fully open there are many yet to come. I look forward to a week or more of enjoying and admiring this great hoya!

The Effects of High Light on Hoya Plants

A very desirable characteristic of a good many hoyas is how their foliage changes colors in various light situations. As a rule, the leaves of a hoya plant is green but in many cases that will change slightly when the leaves are exposed to bright light. I see most of the drastic reddening of leaves during the winter months as opposed to the summer months when the sun is brightest. This fact in itself is confusing to me. The sun is hottest and brightest during the summer months here in Florida. But, what is the exact reasoning behind what causes the leaves to turn a blush to even a total burgundy color. The species that come to mind include Hoya obscura, Hoya sipitangensis, Hoya flavida and Hoya sp. Gunung Gading. There are many more but these are a great start to the long list of red leaves on Hoyas.

Here is the exact plant, Hoya sp. Gunung Gading last summer and today after if had been under a metal halide light for the past 5 months. My next question is…will the leaves return to green while they are growing under the Florida sun for the next 5 months? Only time will tell and I will report back in the fall or when I notice a significant change.

Species Detail – Explanation for these symbols

While browsing the website I sure you have seen this table which has been customized for each species of hoya.  I am hoping with the simple diagram below you will gain understanding of my intentions for each symbol.  This is to be used as an “At a Glance’ guide and of course you may have different finding while growing these plants in your environment.

Hoya Blooms in Green as well as Yellow – Hoya sp. Fidjii

I have been growing this hoya for a few years now after acquiring a tiny cutting from overseas. When it arrived the leaves were curled and the stem was limp but viable. After a week in my ICU area…it rooted and took off growing nicely. The only thing is that no matter how much I tried to change it’s conditions or nutrients, the leaves never uncurled. So I have learned and accepted the fact that this is they way they are supposed to be. Please do not over-water because you might think that is the reason…it is not! This time the blooms were a lime green, although the photo do a terrible job depicting this shade of green.Hoya sp. Fidjii IF IF IF

Hoyas Feel Effects of 45°F Temperatures

Due to the fact that the temperatures in Florida were very warm for most of the winter I decided to slowly move the Hoyas outside to their summer spot. On or about March 1 is the normal date when I begin doing this. The sun has positioned itself high enough in the sky to clear the large trees found outside my screened lanai and give the plants 5-6 hours of bright sunshine. Almost a week into loving their new place in nature as opposed to being under artificial conditions inside the garage/greenhouse the nighttime temperatures begun to drop into the 50s but since they climbed each day into at least the 70s, the plants did not suffer. When I accomplished relocating about 30% of the stock the weather forecast disappointed and predicted cold nights and cool days (40°F/60°F). At this point I know I either had to move all of the plants back inside or grab my blankets and a friend and tuck in the plants for the entire week of unfavorable weather. I chose the latter since I believed I could protect ‘everyone’ with my velux blankets which were thermal but very light weight. as the wind blew the first night I cringed and hoped the blankets were still covering all of the plants. I learned they were in place for the first cold night. The second day as the wind whipped through the screened enclosure the ends of the blankets broke loose and I tucked them in again just before dark.

This continued throughout that week and I thought for sure all of the plants had survived without damage.  At first glance I was right but as the days of warm sunshine continued, I noticed one by one, leaves turning yellow and then transparent and then mushy and then falling to the ground. Ugh, what an awful feeling since it happened so gradual and slowly. I would remove the damaged plant and take it inside under the lights to keep an eye on it. At the end of the two week period, following the week of cold, I had transported about a dozen plants inside and I then had to decide whether to take cutting and begin a new plant of nurse the existing back to health hoping the roots were still viable.

I now have all of the plants either in rooting stage or pruned completely back or most of the the leaf damage removed and I am left with a very sad specimen. Since most do not have to experience this trauma I thought I would share some of the results from hoyas that just got too cold.
