New Huisman Rhododendrons

Rh. 'Lily Dance'  (Z. 00-13) is a cross of (Rh. yakushimanum FCC  x  Rh. 'Goldkrone' )  x  Rh. 'Whitney's Tigerlily' .

          After about 25 years of hybridizing with rhododendrons and azaleas (see page about hybridizing) one of my hybrids, Rh. 'Helen Martin' is in trade since 2002.
Since then we tested many of my best hybrids before introducing them, to be sure they are something new and good enough to introduce. Testing about winterhardiness, health of growing well and fine flowers with eventually new charactaristics like double flowers or with many dots or new colours. I am working together with a nursery in northern Germany, testing about 150 of my best hybrids - quite an intensive work of many years! The results of this testings sofar, are, that we have introduced 6 of the best hybrids on the Rhodo-Show in Westerstede in northern Germany. The place to be every 4th year to see the best new introductions of the last 4 years. I am very proud to tell that I got 2 golden and 2 silver-medalls for 5 nominated new hybrids. This Rhodo-Festivall was from May 15 till May 24. Now I present here these new hybrids with pictures and 4 albums to give you an impression of these 'showpieces of beauty' as I hope they are!! For private selling you will have to wait some years, they are now only for wholesale.  See also the website  For more information, please write to me.  See below 5 new albums about new Huisman rhododendron hybrids in future!!
Rh. 'Helen Martin'  in trade since 2002

®                                                            Rhododendron 'Helen Martin' 
This already named hybrid is for sale since 2002 and many rhododendron lovers have it in their garden. Latest figers show, that it is becoming more popular!!  It probably is a cross with Rh. Cunningham's White' and Rh. 'Cosmopolitan'. The plant grows quite compact to about 4 feet in 10 years. It always depends of  fertilizing and sunlight or more shade The plant itself is very beautiful with concave dark green leathery leaves, remaining on the plant for 4 years!! The flowers open dark margenta red, then turn into a pink-red flower with a white center and in this center a dark blotch. With a red edge. After a week or so it gets lighter, like all rhodos do, but the flowers will remain at least 3 weeks, depending on the weather, much sun or less sun. In a protected area about 4 weeks, which is quite a long time for a rhodo flower! Propagation is very easy and quick! Coldhardiness is very good to at least - 24 C.\ -12F. Flowering time May. Compact to 3 feet in 10 years. Selling address see below.

Gold medal winner Rhodo 2010 in Westerstede, Germany!! Rhododendron 'Double Dots'  is zaailing=seedling =cross  Z. 512. Which is a cross of Rh.' Whitney's Tigerlily'  x  (Rh. 'Graf Lennart' x Rh. calophytum) ®                                                            Rhododendron 'Double Dots'
Gold medal Rhodo 2010 in Westerstede, Germany.
This is seedling Z. 512, a cross between Rh. 'Whitney's Tigerlily' x  (Rh. 'Graf Lennart' x  Rh. calophytum). The special thing about this hybrid are the double flowers, which means, that the normal tiny green calyx leaves have turned into large petals with the same colour as the normal petals. Light pinkish white with dots all over all the petals, a 'heritage' of the mother Rh. 'Whitney's Tigerlily'. Growth is upright to about 5 feet in 10 years. Hardy to at least -5F (-21 C) Flowering time is mid May. Rather compact habit up to 4 - 5 feet in 10 years. Selling address see below.   Larger Photo Rh. Double Dots   only privat use!!
Rh. 'Gerstenkorn' =  Z. 01-98 = Rh. 'Whittney's Tigerlily' x (Z. 90 x Rh. yakushimanum ®                                                            Rhododendron 'Gerstenkorn'  
Cross Z. 01-98 - a complicated cross of Rh. 'Whittney's Tigerlily' x (Z. 90 x Rh. yakushimanum FCC).  Z. 90 is Rh. 'Cunningham's White''  x Rh. 'Sappho'. You can see the influence of the female parent because of the dots, mostly on the upper lobes. And  Rh. 'Sappho' plays her role in the blotch which is dominant in next generations. Special is also, that this blotch devides in 4 parts on 2 lobes. See larger photo. The plant habit is quite low and compact - in 10 years about 2-and a half feet (70 cm) with short dark leaves and more or less red flower buds. Hardiness till at least -5 F( - 21 C). Flowering time in May. Compact growing to 4 feet in 10 years.
Named after a nurserist in Westerstede, who is selling some of my new hybrids. Not nominated this year.

Z. 00-13 is a cross with (Rh. yakushimanum FCC  x  Rh. 'Goldkrone' )  x  Rh. 'Whitney's Tigerlily' .  Same rhodo as right up this page on top. ®                                                            Rhododendron 'Lily Dance' 
This (Z. 00-13) is a cross of (Rh. yakushimanum FCC x Rh. 'Goldkrone' ) x Rh. 'Whitney's Tigerlily' . Again this last male parent  playes an important role - I brought it back home from the 1993 ARS Convention when we visited the Whitney nursery in Brinnon, WA. This cross - see the large photo on top richt (click on it) has very special flowers. The calyx petals are narrow, bearing a blotch as a repeat from the blotch in the normal petals. Because the trusses are quite open, this is visible very well. It resembles the short dancin skirts of a ballerina. Quite unique! Plant growth is strong upgoing to about 5-6 feet in 10 years. Flowering time is mid May. Hardiness to about -10F (-24C). Not yet nominated. A bit shy to flower in the first years. Selling address see below.    Large Photo Rh. Lily Dance   no commercial use!!
                                                            Rh. 'Sun Star' 
This deciduous azalea Rh.  'Sun Star' (former seedling Az. 03-17) is a very special rhodo. Originally arisen from seeds of Fred Minch from the USA. I made new crosses with the offspring and here are some results. See also below 'My Reini'. It is a luteum cross with double fragrant  flowers. The flower buds open dark salmon-pink; then opening up to yellow flowers. After some days this yellow turns into a soft orange!! Look at the picture!! Sunny colours changing into orange stars!! 
The plant itself is very hardy; flowering time May. Till 5 feet tall in 10 years.

Rhododendron 'Prinses Máxima'  is a very complicated cross: (Z. 91 x Z. 94) x Rh. 'Whitney's Tigerlily'. Z. 91 is Rh. 'Goldkrone' x Rh. yakushimanum, Z. 94 is Rh. 'Cosmopolitan' x Rh. 'Scintillation'. Z. 94 had already many dots, this one even much more. ®                                                            Rhododendron 'Prinses Máxima' 
Silver medal Rhodo 2010 Westerstede, Germany.
This is a very complicated cross: (Z. 91 x Z. 94) x Rh. 'Whitney's Tigerlily'. Z. 91 is Rh. 'Goldkrone' x Rh. yakushimanum, Z. 94 is Rh. 'Cosmopolitan' x Rh. 'Scintillation'. Z. 94 had a lot of dots, and this cross has even much more dots, spread all over the lobes. And in this case on the double flowers!! This hybrid could become a bestseller, also because of the name of the Dutch princess, who is married with the Crown prince of the Netherlands, Willem Alexander. On the larger picture you can see the doubleness of the fine flowers. Very soft pink-white and darker red dots. The calyx petals are as big as the normal petals, sometimes even bigger. Very unusual. The trusses are not so big, and this is a good thing, because with rainy weather the trusses don't hang down!! Quite strong upright growing plant of  5 to 6  feet in 10 years. Flowering time is mid May. Coldhardy to at least -5F (-21 C) Selling address see below  Big photo Prinses Maxima
Rh. 'Split Up'  is a cross with Rh. 'Furnival's Daughter' with clear pink flowers with separated petals. .®                                                            Rhododendron 'Split Up' 
A cross with the female parent Rh. 'Furnivall's Daughter' with bright pink flowers, which are splitted at the base of each flower. The honour for this hybrids is to a bee or other insect, not for me. Insects can be very good breeders!! Each flower has a small golden brown blotch. The leaves are rather broad and large on a broad medium high growing plant. The petioles are more or less purple. A sturdy plant and hardy to at least -5F (-21 C). Flowering time first half of May. Shy flowering in the first years. Compact and sturdy growing to 4 - 5 feet in 10 years.
