Tanacetum Parthenium ‘White Bonnet’ – ( Double Feverfew)
A great litte underused plant for the cottage garden which is easy care and useful as a cut flower.
This plant is rarely grown. It has anemone centred double white flowers on a tallish plant. It has a bushy growth habit and has aromatic leaves. It is a very useful and attractive filler for mixed borders.
This plant could be described as a short lived perennial but once established it self seeds and replaces itself without ever becoming weedy.It will grow anywhere but prefers well drained soil preferably enriched with some compost. In partial shade the foliage becomes larger, greener and more fern like. In February cut your plants back hard as the foliage is often marked and damaged by leaf miner, the only pest which seems to affect it. Under growing conditions which suit it , plants can reach 60cm and the mass of tiny white daisy flowers on tall stems make it a terrific cut flower.
For best results, sow seeds immediately onto a good soil-based compost. Cover the seeds with fine grit or compost to approximately their own depth. They can be sown at any time, and germination can sometimes be quicker if kept at 15 to 20 degrees C. However, one can also sow most seeds in an unheated greenhouse and wait for natural germination as many seeds have built-in dormancy mechanisms, and often wait for spring before emerging regardless of when they are sown. But spring sowing will obviously give them a full season of growth if successful germination occurs.
