Hoya carnosa var. carnosa x Hoya serpens (BE24)

cultivar

This hoya is a hybrid between Hoya carnosa var. carnosa and Hoya serpens. When Emilio Begine in Belgium had these both plants in bloom on his patio insects did the pollination for him. This hybrid is widely known as Hoya 'Chouke', but it has not been formally published (or registered), so Hoya 'Chouke' is not a valid name. It has been described in Fraterna 16(1) (2003) by Emilio Begine.

This hybrid is the sister seedling of Hoya carnosa var.  

carnosa x Hoya serpens (BE23). It reminds more of Hoya carnosa var. carnosa than BE23; the leaves have the same shape as Hoya carnosa var. carnosa (even though they are smaller) and it is trickier to get in bloom. It is a fast grower and it  produces a lot of peduncles, but it took almost three years before I got it in bloom for the first time. Even though it is tricky to get in bloom this is a hybrid that I recommend. The slightly pubescent foliage is lovely and the flowers are beautiful. I grow my plant in a shaded place in my garden room where nights are cooler. 

Left most; the buds just a few days before they opened. To the left; the flowers have been open for a few days and the nectar start dripping.

BE24 is a cold growing species so it tolerates temeperatures just less than 10°C for longer periods. I grow mine in the garden room where it thrives. I have it supported on a trellis as it's a good climber like Hoya carnosa var. carnosa.

The picture at the right shows Hoya serpens at the top and Hoya carnosa var. carnosa x Hoya serpens (BE24) below it. The scent of this hybrid resembles the scent of Hoya carnosa var. carnosa. 

Right most; a picture of the pollinarium which measures 0.85 mm.
