Hydrangea paniculata ‘Breg14’ Polestar is described as a very early blooming Dharuma crossbreed. The jury from the Royal Boskoop Horticultural Society commented: “Very well cultivated and presented. Flowers very abundantly. Does not seem to be invasive. The light green colour of the flowers is a definite innovation.” [read more]

Hydrangea paniculata ‘Couhaprim’ Prim’Red is bred by Jacques Couturieux. French royalty management agency Sapho submitted this cultivar to the new plant contest. It is selected because of its early maturity and changing flower colour. “At the end of May or beginning of June, the flowers are cream-white. The colour turns into pink and then red within two to three weeks. The flowers retain this red colour for a long period of time, up till July/August. The large panicles are elegant, with sterile flowers ranging from pink to bright red, as well as fertile flowers, which are red. This radiant colour remains for a long time, into July and August, sustaining the interest of the plant in comparison to typical paniculata like Dahrumas, which have a tendency to fade quickly.”
Prim’Red grows as a small shrub up to height of 1.5 m, with slender, straight stems.

Hydrangea paniculata ‘HPOPR018’ Early Harry is an introduction of Oprins Plant from Rijkevorsel, Belgium. It is an early-flowering cultivar among the panicle hydrangeas. “The creamy white flowers slowly develop a pinkish-purple glow. The most important advantage of the Early Harry is its early flowering, with the first buds clearly visible in May. Because of this, the plant can be supplied at the height of the trading season.” Dutch royalty management agency Van Vliet New Plants submitted the plant for the novelty showcase.
Early Harry will also be one of the new introductions that UK-based Seiont Nurseries will present at the National Plant Show 2018, which will be held June 19-20 at Stoneleigh Park, Warwickshire, England.

Hydrangea macrophylla ‘TK02’ So Long Sunny is an addition to the series of repeat flowering hydrangeas for cold climates, which was introduced to the European market by French royalty management agency Sapho in 2017. Yasuhiro Takahashi from Narita City, Chiba (Japan) bred this plant. So Long Sunny blooms according to the agency abundantly throughout the summer with beautiful, rounded umbels. “The white petals are curled with vivid pink edging. The flowers turn pinkish-white when in bloom. This variety develops shades of sky blue when planted in acidic, aluminous soil. Due to its compact growth and sturdy stems, this plant is a good garden hydrangea that is suitable as a stand-alone, in groups, as a low hedge or in a large container.”
French nursery Renault submits So Long Sunny to the new plants contest of the Salon du Végétal 2018 which will be held June 19-21 in Nantes, France.

Hydrangea ‘USHYD0405’ Runnaway Bride Snow White was submitted by royalty management agency Cultivaris (Germany/US) and bred by Ushio Sakazaki from Japan. This new, interspecific Hydrangea hybrid flowers in spring and early summer. “Not only at the shoot tips, but also on all the previous season’s side buds. After the first flush of bloom, new terminal flower heads appear on the newly-grown shoots. This extends the flowering period up to autumn.”
“The unique shape of the flowers and elegant growth habit also make the plant suitable for hanging baskets and growing on trellises.”
Garden Trials and Trade 2018 – a spinoff of the Dutch trade fair for hardy nursery stock Plantarium – started yesterday. Tomorrow is the last day of the show.
