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 www.rhodo.de For more information, please write to me. See below 5 new albums about new Huisman rhododendron hybrids in future!!
Rhododendron 'Helen Martin'
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!!
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. Selling address see below. Big photo Rh. Gerstenkorn only privat use!!
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.
A fine asset to the rhododendron world of deciduous azaleas. For bigger picture click here 1920 x 1280 px (free for personal use)

Rh. 'My Reini
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 copyright Tijs Huisman
|.® Rhododendron 'Blue Print'
This cross is Rh. 'Eruption' X Rh. 'Janet Ward'. 'Eruption' is a Hachmann
hybrid wit bicolor flowers, red and white. ‘Janet Ward’
is an old hybrid wilth pink flowers and white edge. So for me this
seemed an interesting cros with may be unexpected flowers. Some results
are really good, like this one Rh. 'Blue Print', under number Z. 00-61.
With purple-blue flowers and a lighter blotch in the middel in the shape
of a white star with a yellow flare. After some days this star gets
darker with age. The habit is middle high with nice foliage and the stem
is purple red and also the leaf stem. Flowering time is mid may,
depending of the weather. Coldhardiness at least - 22 C. Click for
larger pictures. And see for selling nurserlies at the bottom of the
Rhododendron 'Sun Fire'
Gold medal Rhodo 2010 Westerstede, Germany! This cross (Rh. 'Rotgold' x Rh. 'Amaretto') x Rh. dichroanthum yellow variety offers a special colour arrangement. The inner side of the flowers is soft yellow and the outer edge pink-orange. On the three upper lobes is a golden blotch of many dots. At a distance it looks bright (2 coloured) orange, a colour which is very popular nowadays. The plant growth is compact with narrow leaves. The new leaves are nice bronze. Growth is quite broad up to 3 to 4 feet in 10 years. The plant itself is hardy to at least -5F (-21 C) - the flowers hardy to 0F, a temperature that is not very common in the last 10 years here in western Europe. Flowering time is mid May. A strong plant in flower beauty and winterhardiness!! Selling address see below. Big photo Rh. Sun Fire 1920 x 1280 px copyright Tijs Huisman
Rhododendron 'Moon Fire'
I don't know the parentage of this new hybrid Rh. ‘Moon Fire’. Normally
I am very precise abouot the jparents of crosses, but apjpearently not
in this case. Nevertheless this is a very nice plant and flowers. A
possibility is a cros between an real yellow American hybrid with the
Hachmann hybrid Rh. 'Goldkrone'. The flowers are a nice golden warm
yellow with dark red spots in the middle. The plant flowers already in a
young stage; some stems have more than just one bud, but many bids. The
result is e very dense 'ball' of flowers. The plant has bronz red new
leaves and grows rather compact till 4 or 5 ft. in 10 years.
Winterhardiness is quite good till at least - 22C. Flowering time mostly
® Rhododendron 'Silver Copper'
This cross has
been made by Fred Minch, Puyallup, WA, USA. Some years ago he died. In
his honour I would like to present this new cultlivar. A cross between a
Rh. yakushimanum hybrid X another yakushimanum hybrid.
With number Z. 337. The flowers are white with a red blotch, really fine
but not exceptional. The new leaves are covered with a silver indumentum
that gives the plant in June and July a silver presence. Depending on
the weather, rainfall it will remain several months. Underneath also
silver indumentum, that turns into copper. This explains the name 'Silver
Copper'. The new buds also start silver and turn also into copper
indumentum. Especially in winter time an appealing sight! The plant
grows quite compact and dense, certainly the flirst years. Very
coldhardy to at least -25 C. Flowering time mid May. A field with
this rhodo is beautiful for the silver indumentum, see picture.

® Rhododendron 'Sun Glory'
The parentage of this new hybrid is as follows: (Rh. Lem’s Cameo’ X Rh. ‘Polynesian Sunset‘) X self. With such beautiful and famous parents, any child must be great also. "Let's make rhododendrons great again".... Before number Z. 504. Large fringed flowers with a combination of colours of yellow, light pink and mostly orange. Total impression is orange. The inner sight below is really glowing in the sunlight! So, the name could have been also Rh. 'Orange Glow'. But so many names of rhodos start with 'orange'. In line with 'Sun Fire' it is 'Sun Glory'. The new shoots have nice bronze red leaves, foliage which is a additional gift after flowering. The plant habit is middle high of 4 to 5 feet in 10 years. Flowering time is mostly mid May. Cold hardiness is good, considering the parents, to at least - 20C. copyright Tijs Huisman
® Rhododendron 'Black Pearl'
Rh. ‘Black Pearl’ is a result of the cross Rh.
Frank Galsworthy X Rh.
‘Jonathan Shaw‘. Both parents have dark purple flowers wilth a prominent
blotch, yellow and black. Yet, I have some doubts about this parentage.
I also ussed some times Rh. 'Melanie Shaw', quite simular of 'Jonathan
All of these 13 new Rhododendron hybrids are officially
registered with "The International Rhododendron Registrar, The Royal Horticultural
Society's Garden", the RHS in Engeland. Besides I registered a special
logo, so if you see this logo ®
you know that this is a 'TH-Rhodo" a Huisman Rhododendron.
Next years there will be more new introductions.
