New Growth on Rhododendrons
David - good to hear from you again. Muggy and clammy pretty well sums it up. I was born in St. Louis, Missouri and never did like the heat. Why I chose gardening as a hobby is beyond me, but I would rather be outdoors. The early spring and fall more than make up for the summer discomfort. Some summers are uncomfortable for days on end, and other years it is sporadic. The work must go on. I worked out there for 5-1/4 hours yesterday and the sweat was dripping off my face. I gave up on wiping it off. You probably read all this on a previous post. Our Ozark Chapter ARS membership is widespread - Mississippi, Texas, Kansas, Missouri, Arkansas and Oklahoma. Leonard Miller in Grove, Oklahoma has done a lot of work on heat tolerant rhododendrons. John Thornton is another member living in a warm climate. They are working to develop heat tolerant hybrids. From what I know of our membership, I am probably attempting to grow more species than the other members. They like the flowers. I like foliage. http://ozarkars.com/data/documents/gard ... easons.pdfhttp://www.lendonwood.com/ Lendonwood Gardens - Grove, Oklahoma - former home of Leonard Miller At 10:30 a.m. today a storm blew in with very high winds and blew over a Peach Cloud that I had planted early this spring. It is a large, top-heavy rhododendron, planted out in the open. We've had high winds since I planted it, with no problems. Suppose the wind was just right today to do that. I am going out there now to get it repositioned. Will check the rain gauge also. We got 1-1/4" rain on 7/4 and 2/10" that night, so we are fortunate in that regard. Let's visit here again soon.

Hi, I am just new here. Below are the new growth of the late sprouting rhodos: Rh. auriculatum and Rh. Polar Bear (cross of Rh. decorum ssp diaprepes and Rh. auriculatum) and

Re: New Growth on Rhododendrons
Welcome Arturas! Great looking R. auriculatum and R. Polar Bear. What other Rhodo's are you growing?
I have a baby R. auriculatum grown from seed.

New Growth on Rhododendrons
Arturas - welcome to Growing On The Edge. Your rhododendron photos are excellent - great color and detail. I'd like to see more photos of your rhododendrons when you have time. Do you have a preference for species or hybrids? Do you grow your rhododendrons from seed? I grow both species & hybrids, and really like foliage, which can be interesting on both species and hybrids.

Re: New Growth on Rhododendrons
Hi all. Thanks for the comment, I growing rhododendron hybrids for some time (most of them of German origins) - have ~50 plants. This year I have started with large leaved species and hybrids. Our location is not very friendly for the in a different way - cold maritime climate - lot of winds and temperature dropping close to -17 C (0 F) nearly every year, summers are mostly cool. So could plant the big-leaved species only in the forest. And the forest is not so nice as yours - heavy clayey soil overgrown with alders, alder buckthorns and bird cherries. So to plant rhododendrons there a lot of terraforming is needed. Out of big-leaved species I have: Rh. auriculatum, calopyhtum, praevernum, rex ssp.fictolacteum, sutchuenense, galactinum, wightii and trallianum. I also have some of species hybrids known for the foliar niceties - Teddy bear (bureavii x yakushimanum), Silbervelours (R. degronianum ssp yakushimanum 'Koichiro Wada' xR. pachysanthum ), Frisia (Rh. campanulatum) and Rh. insigne. Other my interests include hardy Rh. cinnabarinium hybrids like Biskra, Wasgau, Goldstrike, Mondshine. I basically started to grow rhodos from seeds also only this year - ordered some seed from ARS exchange (mostly expecting nice foliage) of this year selection: 16-4 h.p. ('Russell Harmon' x rex) X ochraceum 04/266 16-8 h.p. 'Bravo' X asterochnoum 98/634 16-10 h.p. 'Nepal' X calophytum 64/063 16-16 h.p. 'Mikkeli' X [(yakushimanum x lacteum) x 'Powder Snow'] 16-291 c.p. 'Goldsprenkel' X rex, Tue Jorgesen 16-8 h.p. 'Bravo' X asterochnoum 98/634 16-19 h.p. 'Summer Snow' X [(BVT*1 x auriculatum) x ('Babylon' x auriculatum)] 16-67 h.p. yakushimanum X ochraceum 16-68 h.p. [yakushimanum x (aureum x '"Prelude")] X viscidifolium 16-136 h.p. [(yakushimanum x lacteum) x (yakushimanum x macabeanum)] X (yakushimanum x wardii) Goal: Yellow, indumentum, big leaves 16-151 h.p. 'Red River' X sinofalconeri RSF87/202 Goal: Foliage 16-152 h.p. 'Red River' X (yakushimanum x falconeri) Flavell Goal: Foliage 16-124 h.p. 'Jurassic Fantasy' X "Kathy Bones (macabeanum X calophytum)"*2 (pollen: Chris Trautmann) Unfortunately my photo gallery site is down now - will try to recover rhodo pictures -which I have a lot, including my visits to different gardens in Europe..

New Growth on Rhododendrons
Arturas - thank you very much for telling us about the growing conditions where you are. It does sound challenging, but having a forest of most any kind is a good thing, don't you think? Your list of species rhododendrons is impressive, as well as the hybrids on your list. I am sure most of us would enjoy seeing more photos of your rhododendrons when that is possible. I am envious that you have R. Silbervelours. I cannot currently obtain that one as a plant, but it has spectacular foliage and new growth. Rex ssp. fictolacteum is one of my favorites in my collection. I would also enjoy seeing your photos of garden visits in Europe - again, when that is possible for you. Perhaps you could post a few at a time? Have you ever ordered seeds from Rhododendron Species Botanical Garden in Federal Way, Washington? That is another good source. Here is the seed order form for Spring 2016. http://rhodygarden.org/cms/wp-content/u ... ders-1.pdfI don't know if you can still order seeds from this list, nor do I know how often they publish a seed list.

Re: New Growth on Rhododendrons
In flower here in coastal Nova Scotia Rhododendron discolor and R. 'Scotian Reef'. Next up should be R. sanguineum ssp. didymum and its hybrids followed by (R. brachycarpum x galactinum) and lastly R. auriculatum.
johnw - +19c & drizzle

Re: New Growth on Rhododendrons
Arturas,
Please post some of your photos, we would like to see them all!
Your seed list from ARS Seed Exchange looks very much like the seeds I ordered. I too enjoy Rhododendron foliage and focus on large leaves. I have not started my seed yet, I need to soon.
Here's a seed grown seedling on its 3rd flush this season, a very aggressive hybrid. 15-388, 'Vulcan' X macabeanum, M. Bones #1, Richard Flavell, CT
Hi John,
Your blooms are beauties! Most Rhodo blooms are done here except for maximum which still has some.
Your hybrids are flushing for a second time this season. Here's one of them. The one behind is also the same hybrid. 14-507, (brachycarpum x galactinum) X [(yakushimanum x rex ssp. rex) x rex ssp. rex)], John Weagle, NS, Canada

Re: New Growth on Rhododendrons
Hi all, I was not able to recover my full botanic pictures site, so instead putting photos from my archive in the new one running currently on the computer in my university office. http://193.219.76.93/plants/So far only some of the rhodos there. Site is mostly in Lithuanian - sorry for that, but all the pictures are clearly labelled in english - species, time and location (Tauralaukis is my garden in the city). I will put some pictures directly in the forum, but there are really too mant of them, so I will do it with only the most relevant ones.

Re: New Growth on Rhododendrons
Hi Arturas, thanks for posting the link to the photos bi enjoyed looking at them. Can you post the photo of 'Dominik'? That hybrid with Calophytum sounds interesting.

Re: New Growth on Rhododendrons
Here goes 'Dominik' - not have flowered yet in my garden
and I have another one with no name (bought without a label at the garden centre), but looks quite similar:
There are several similar hybrids of Rh. calophytum developend by Hans Hachmann in Germany: 'Sarastro' , 'Caramba' , 'Hachmann's Oktavia" and 'Monteverdi' . At least 'Dominik' is very hardy and robust even in the windy location without any protection.

Re: New Growth on Rhododendrons
Tim, How are your Rex'es indeed? I got some trouble with my fictolacteum. First, the wind has destroyed several leaves and I moved it further in the forest. Here a leaf rot took it's share on the leaves and central point didn't grow at all. I have treated the plant with a systemic fungicide and it seems to survive :
