Can Cardinal Hume take the heat?
Comments (7)I imported Cardinal Hume from the Harkness Nursery in Britain in 1984 and grew it in Granada Hills, CA from 84-89 and in Newhall, CA from 89-2006. The plant did splendidly in both climates where summer temps could spike to triple digits. In the years it grew in Newhall, it experienced a hundred degree temperature variance between the winter low of 15 and highest summer spike of 115. July through September is usually in the nineties to low hundreds many years. The plant grew very large, flowered heavily and remained totally clean due to the aridity. The flower color is dark enough that in brilliant sun and high heat, the petals will fry easily. I loved that rose from the first catalog photo I saw of it and I love it still. One of its greatest attributes to me is the scent. To me, it smells just like the candy, Red Hots, taste. I raised a poly type seedling from Cardinal Hume that Sequoia Nursery introduced called Purple Buttons. It has the same flower color and scent, only in a much smaller plant. A link to it on HMF is below. You could also try International Herald Tribune, a very deep violet poly type shrub. There are also violet polys such as Baby Faurax, Werner von Blom and Lauren. Louis Lens raised some hybrid multifloras in those colors such as Violet Hood, Sibelius, Verdi, Rosy Purple and Jet Flame. If black spot is an issue where you want to grow it, be prepared to spray Hume. You'll find the plants have little issues with the temperatures. It's the depth of the petal colors which will cause them to fry in high heat. Kim Here is a link that might be useful: Purple Buttons...See MoreWhat will thrive in heat and humidity?
Comments (10)I'm wilting in the heat but my plants are doing surprisingly well considering we've had very little rain and can only irrigate once a week. They are heavily mulched with newspaper and some shredded bark (just enough to cover the paper). Here's what is doing well for me: roses (mostly own root heirloom types, chinas and teas), salvias, lantana, dune sunflower, jatropha, daylilies (my latest craze-so pretty), sunflowers, gaillardia, rudbeckia, guara( LOVE this plant and so do the bees), starry rosinweed (blooms constantly cheerful yellow), passionflower, periwinkle. daylily-Upper Crust Society rose-Souvenir de la Malmaison rudbeckia The ones that die on me in the heat are: fuschia, cuphea, geraniums, parsley (this last weeks heat did it for them), zinnia, snapdragons. Tomatoes sulk and do not grow an inch. I don't blame them. I am zone 9.5-10 so YMMV. Denise...See MoreHeat tolerance/ low humidity- coconut palms
Comments (6)I think that as long as its humid they can handle a lot of heat. But in the tropics temperatures never or very rarely exceed 100F. 98f in Florida is a very serious situation. Coconuts really dislike dry heat, but if a coconut palm is in afternoon shade and misted, it can handle 115F. I think anything warmer and you would probably be cooking it! Good luck!...See MoreBlue Flowers, that can take the Heat..........
Comments (23)Larkspur is great. comes in all colors but my favorite is blue. germinates at 50 degrees, is the first to grow in my phx/mesa garden and reseeds itself easily. mine start in november, grow thru feb, start to bloom in march - july and take NO WORK. they can get 4-5 feet tall with space. I let mine grow thickly and they get 3.5 feet tall. they require no work and will grow in grass, weeds, manicured flowerbed, whatever. they will bloom better in full sun, and I'm talking about our hot desert sun. just broadcast seeds and water. the seeds are tiny.
