Pyrethrum plants

Pyrethrum plantsThe greenhouse kinds of the Pyrethrum grow in any rich soil, and young cuttings planted under glass root readily. The hardy kinds are not particular as to soil so long as it is not cold and wet, and are increased by seeds sown in heat in February if wanted for early use, or in the open during March and April for later growth.

The crowns of the Pyrethrum may be divided either in autumn or spring: each eye or bud will make a fresh plant. Young plants produced in this way in the autumn require the protection of a frame during the winter.

The Pyrethrum flower in July and their height varies from six inches to three feet.
