Hi Amber! Here is a link from Doug Chamberlain of Vermont Hoyas. You should look into Hoya burmanica as it might take down to 5 degrees Celsius (you do the Fahrenheit on that one ;)). It is also a totally uncomplicated plant to grow. Kami Here is a link that might be useful: Temperature tolerance guide

Paula I think you may have matched the wrong photo up with the caption. Hoya subquintuplinervis does have thick, rigid and similarly veined leaves to my Hoya sp Sulawesi but it was originally collected in Thailand and my plant is from the large island of Sulawesi which is located off of the eastern shore of Kalamantan on the Island of Borneo and below the Philippine islands which apparently most heavily influence the flora of the Sulawesi. I included a map of South East Asia in case anyone wanted to take a look. It is interesting to look up the locations where many of the unidentified Hoya species were collected, Islands like Ambon, Palawan, Haraku and Molukken. Part of determining the proper name for a species lies in the area of it's origin. Some species have a very large range while others are endemic so even though many Hoyas look alike they may in all reality not be as closely related as they appear. Many of the smaller islands are obviously not included on the map but there are several of the ones I mentioned. Mike Here is a link that might be useful:

Lee, You're welcome. When you used the word 'panic', I wondered if I should be panicking too. I'm glad to hear the answer is no. : ) It is a great relief that the Euro is backing off a bit on the freezing temperatures. Let's hope that the chances of frost start dropping too. I hope you have a great visit with your parents, and I hope the weather behaves itself so y'all can have a good time together without having to run for shelter. I can handle frost. Freezes worry me, even with row cover, but mostly because all the trees, shrubs, perennials, etc. are emerged and leafed out and I cannot cover the whole yard. My hollies (old and well-established) suffered massive damage when we went to 28 degrees, and normally that wouldn't happen. However, we'd been having a lot of days in the mid-80s or warmer, and nights in the 50s-60s, and the hollies had lots of new growth that wasn't conditioned to sub-freezing temperatures. On the other hand, Johnson Grass growing outside my garden fence and attempting to creep into the garden froze back to the ground. Of course it isn't dead, but at least it has been set back for a while. For future reference, to find row cover and frost blanket fabric in large enough sizes to cover anything you can envision, you can visit the website of Agricultural Solutions. That's where I find my frost blanket. I bought it in 12' widths, but they have it available in many widths---some of which are so huge that they clearly are aimed at commercial farms. Most places have it in only more narrow widths. I like the 12' width because you can cover a row of fairly tall (well, fairly tall for early in the season) plants with it. If you buy a roll they have it folded in half on the roll, which helps keep the shipping charges lower since it is a box a little over 6' long instead of 12' long. The very first row cover fabric I bought around a decade ago was 6' wide which sounds good, but really isn't. I was using it on 4' wide beds, so I couldn't cover a whole bed with it once the plants were any taller than 11-12". I've discovered that with row cover, wider is better, particularly since I grow in raised beds that are mostly 4' wide and often I have some plants that are knee-high to waist-high by the time the last threat of frost has passed in the first week of May. If the strong storms the next few days don't pound our plants into the ground or carry them away with the wind, we all might get to begin the month of May with gardens that are in pretty good shape. I like the idea of cooler temperatures. The longer we stay cool in Spring, the better the cool-season crops will produce, and the better the fruit set on the tomato plants. I did look at my Accuweather forecast the last couple of days since it goes out farther than the NWS forecast on the Norman webpage and farther than our local TV forecast, and it showed my lowest low next week of 43. Today that's been raised to 45. I'm starting to feel a lot better about next week's weather, but that doesn't mean I will become complacent and stop watching the forecast. I'll be watching it like a hawk. Dawn Here is a link that might be useful: One Source for Large Sizes of Row Cover This post was edited by okiedawn on Wed, Apr 23, 14 at 12:09

I've watered and covered my tomatoes and peppers. I'm not worried about anything else. I just don't want the tomatoes to be stunted by the cold. Oh, and I had a coleus plant overwinter in the greenhouse this year. It was a volunteer in my pot of sage and I figured it wouldn't make it through the winter, even in the greenhouse. Obviously, I was wrong! If we keep having winters like this, I'm going to look into more plants.
