Yucca filamentosa 'Rigmor'

Variegated plants are often valued by gardeners and rare forms are sold to high prices. With some plant generas breeding for new variegated forms is easy like with Hostas. For other families only one in a million or at least one out of 1000 seedlings shows the wanted variegation.

Within the genus Yucca serverel variegated forms are known. 'Color Guard' and 'Golden Sword' being among the most common and these are easy, cold hardy plants. Another plants often sold in garden centers is Yucca gloriosa variegata. Showing lots of variegation the plant is not particular cold hardy and it dislikes both our summer and winters here in Scandinavia, both being too cold, too wet and the winter too long.

Some years ago I sowed a handful of seeds from a Yucca filamentosa collected in Connecticut. 3 plants germinated, one being with green yellow leafs and one showing variegation.

One of the yellow, green Y. filamentosas from Connecticut.
The flowers were yellowish and bell shaped.

Yucca filamentosa 'Rigmor'.
It does share similarities to Yucca gloriosa variegata but is much more hardy to both cold and rain. I decided to name it after my daughter Rigmor.

The flowers were very different from the other clones wíth almost pure white flowers. So far I have not distributed the plant as it is a very slower grower.

More carnivorous plants...

Its really getting colder now and all the plant action from 2012 has ended. Sarracenias is really a highlight of the summer as most of them wont start growing until end May or even mid June. These are pictures frpm July.

Sarracenia x (catesbaei x purpurea).
Another purpurea-hybrid.
Sarracenia flava maxima from Virginia.
Sarracenia oreophila.

Carnivorous Plants 2012

This year has been a real succes when it comes to the carnivorous plants in the garden. Despite a really cold winter with temperatures on serverel occations down to minus 24C and even colder for a few hours, all the plants survived outside. Now around 300 different carnivorous plants grow healthy in our danish Z6 garden. Here is a few examples - much more to come:

Sarracenia (purpurea venosa x catesbaei) x oreophila.
Sarracenia courti x purpurea.
Sarracenia x catesbaei in bronce.
Yellow Sarracenia x catesbaei from a locality with naturalised pitcherplants in Denmark.
Sarracenia leucophylla hybrid.
Another leucophylla hybrid. Leucophyllas are not hardy outside as our summers are too cold, but mixing them up with S. purpurea genes sure helps.
Here is another Sarracenia from the danish locality. Here the purpurea genes are obvious.
Of pure species Sarracenia purpurea purpurea forms, oreophila and flavas are the best. But mixing their genes with more tender species certainly improves the selections of what can be grown outside.

Gladiolus dalenii

As a surprise this spring, Gladiolus dalenii proved hardy in our past winter despite of a low of minus 24C. Growing not too far from the house they experienced some sheltered and were not too wet in winter, but still, they are from Africa. They flowered for serverel weeks in July. The plants are from wild collected seeds and showed some variation.
