Equisetum hyemale-Rough Horsetail

Propagating Rough Horsetail is simple, however be aware it is invasive if it is not planted in a container, because it grows by underground rhizomes and since it is a moisture loving plant it is not easy to locate rhizomes under water. This plant could date from the Paleozoic Era and existed for millions of years because extinct fossils with stems the size of tree trunks have been discovered. It is native almost world wide from North and Central America, Asia and Europe. It can grow up to 5' is evergreen in some locales and its hardiness Zone is 3-11. It’s stems reminds one of Bamboo.

Propagating Double Hemp Agrimony is as easy as digging up the main plant in spring, before new growth, and dividing the clump into how many transplants you desire. It is a native to Europe where it is used as a commercial cut flower. Under optimum growing conditions the plant can reach 8'.

Peucedanum ostruthium “Daphnis”-Variegated Peuce Materwort

I am not familiar with this plant and because of that I could not find anything on propagating other then by seed, stratification of 4 weeks, however because the plant forms a clump you might try dividing it in the spring, but since it is a native of France, it will not be easy. The plant itself is poisonous and will cause skin irritation so wearing gloves and long sleeve shirts when gardening around it is necessary. It is also very fragrant and its flower resembles Queen-Anne’s Lace that bloom through early to mid summer and will reach a height of 24". The plant prefers a partial or full shade exposure with a moist well draining soil and is hardy in Zones 5-9.
