Michauxia tchihatchewii
Catherine Wheel Flower n]]
10 seeds 2.45   
JS1473

(Click here for Larger Image) 

Quantity: 

I first grew this spectacular flower about 10 years ago and they are indeed wheel like, with about 20 white petals radiating from a central pale yellow hub. Each individual bloom is about 4 inches in diameter, and dozens open up simultaneously on plants up to 5 feet tall. Large numbers of buds extend the flowering period to at least a month. The leaves are produced mostly as a ground-hugging rosette; they are tough, deeply notched and covered with stiff hairs that people with sensitive skin might find irritating. Like a few other members of the Campanula family, Michauxia is a biennial - it blooms in its second season from seed and then dies. But growing it from seed is easy, making annual replacement of the plants no chore, just as gardeners are used to routinely replace biennial foxglove plants. A choice and rare plant.

Colder winter temperatures below -8C will tend to cut them back and the resulting new growth the following spring takes longer to flower. Best for milder gardens or in protected positions.

Perfect for providing autumn interest in well-drained areas of the garden. The papery lanterns make wonderful dried flower arrangements. To prevent them from becoming invasive like mint, leave space around them to manage the plants or keep in containers. We just dig them out from where we don't need them but no big problem to control.

This is an eye-catching plant with heavily felted, silver-grey rosettes of large leaves that look outstanding in winter. From these, tall, furry, silvery flower-spikes emerge in early summer.

After flowering, the spikes still look attractive for months before starting to die off.

(Click here for Larger Image)

Quantity:

The plant will take a few years to reach maturity and flower but well worth the wait, it can also be used for bonsai work if you prefer. I have also grown these as standards in a central lawn location, requiring some support for a few years but the cascading effect in flower was quite spectacular.
