HEDERA (Araliaceae)
We have a few named varieties of Ivy which, when used wisely, make excellent garden plants. They are attractive all year round, and are valuable for masking unsightly objects. They make good cover and nesting sites for birds and produce flowers late in the year which are a magnet for bees and butterflies. They make good ground cover where other plants struggle - in dry dark shade. Problems arise when Ivy is planted in the wrong place or, more often, not kept in check. Avoid planting on a wall with loose mortar etc. or where the growth will find a way into and behind gutters etc. Ivy's main aim in life is to climb, and produce flowers, so avoid letting it go up your favourite tree. Ivy seldom kills trees directly, but can weaken them by starving them of food and light, and can make them more prone to being blown down. When Ivy reaches the top of its support, it changes to the arborescent form (i.e. stops being a climber and becomes shrubby) and starts to flower. If you have space for this to happen the local wildlife will love you.

HEDYCHIUM (Zingiberaceae)
(ORNAMENTAL GINGER.) All gingers have vigorous rhizomes which can be really tough to dig out of the ground when it comes to dividing clumps. We suggest that you grow even the hardier species in a large plastic pot, which can be sunk into the ground if necessary and bring them undercover for the winter. This has the added adavantage of bringing them into flower sooner. Grow in loam based compost, protected from hot sun & water freely in summer. If grown indoors ensure ample humidity is provided. Along with Cannas, Gingers like to have the leaves sprayed with water (not in direct hot sun to avoid scorching) Keep rhizomes just moist in winter. Divide in spring.
