This document summarizes information about the Hypericum genus of plants, commonly known as St. John's wort. It describes that there are over 490 Hypericum species, ranging from small herbaceous plants to shrubs up to 2 meters tall. Several popular ornamental Hypericum species are listed, along with details on their cultivation for flower arrangements. The document then focuses on Hypericum perforatum, providing information on its production including soil preparation, planting, growth conditions, pest management, harvesting and marketing.
2. Description
•Hypericum L.
•All members of the genus referred to as St. John's

perennials 5–10 cm tall to shrubs and small trees
up to 2 m tall. JMUBanayag
3. • There are over 490 species in the

4. Ornamental Plants
• Hypericum spp
• Availability: year round
• Bunch size: 6-10 stems
• Vase life: 14 to 21 days
•Hypericum is a dramatic success story. In fact, it
ranks as the most successful berry-bearing cut
floral material to date.
•From just a few acres of production in the 1980s,
hypericum is now ranked at number fifteen in sales
through the Dutch auctions.

13. Why does everybody love
hypericum?
•Let’s start with the obvious.
•The smooth, shiny berries provide
textural contrast to the satiny petals of
many flowers, creating strong visual
interest.
•Breeding has expanded the color range
from the classic rusty reds and browns to
the newer pink, green, gold, red, and
even salmon and cream colored varieties.

19. Production of Hypericum
•Hypericum is also grown in equatorial
countries, especially Ecuador and (for the
European market) Zimbabwe, where it can be
cut and shipped all year long.

28. Field Planting
• Rooted cuttings can be planted
directly into raised beds or pots.
• Distance of planting varies
according to the season and
variety of the crops.
• Conventional spacing
– 22 x 20 cm JMUBanayag
29. • Cuttings are taken from a healthy stock
plant.
• About 10-12 cm length of cuttings or
about 3-4 nodes.
• Cutting should have at least 2-3 leaves
to reduce transpiration
• Cuttings are dipped in rooting hormone.
• Cuttings are put in sand beds in shade
conditions.

31. • Cuttings leaves looks fresh due
to reduced transpiration.
Hypericum leaves are cut to
lessen transpiration.

40. Support/ Staking
• It is necessary to support the stems as the
crop matures.
• Hypericum are tied to bamboo stakes,
trellises twine or sturdy sticks to keep them
erect and properly hold berries or the main
stem of the berries. JMUBanayag
