One to five seeds are in each berry, which are dispersed after being eaten by birds. [10] [11] [12] Subspecies [ edit ] While Boston Ivy is a popular plant that many people mistake for a true ivy, it is not actually in the genus Hedera . Instead, it belongs to the family of plants known botanically as Parthenocissus – the grape family . It is a perennial, deciduous vine with broad green leaves. It is this non-ivy ivy that gives “ivy league” universities their name. Ironic, when you pause to think about that error. Boston ivy is particularly beloved for the way its leaves glow bright red in the fall and early summer. With inconspicuous flowers, this plant produces small blueberries that birds enjoy . The species differ in detail of the leaf shape and size (particularly of the juvenile leaves) and in the structure of the leaf trichomes, and also in the size and, to a lesser extent, the colour of the flowers and fruit. The chromosome number also differs between species. The basic diploid number is 48, while some are tetraploid with 96, and others hexaploid with 144 and octaploid with 192 chromosomes. [2] Ecology [ edit ] Known as Common ivy, European ivy, English ivy, or just ivy, Hedera helix is a climbing evergreen plant native to Europe and Western Asia. It is a rampant and voracious plant that we can see all around us – on walls, in gardens, taking over city streets, and flourishing in the parts of native habitat that remain. Helix derives from the ancient Greek “ to twist or turn ”. It is also sometimes referred to as Bindwood and Lovestone. Ivy is said to be responsible for certain forms of dermatitis and skin rash (in susceptible individuals), further details can be found in the Botanical Dermatology Database.Ivy has also been used in a number of ways; see this pdf file about the plants in The College Garden of the Royal College of Physicians.

Weedkillers for gardeners (Adobe Acrobat pdf document outlining different weedkillers available for gardeners; see sections 1a and 4) Links: When cross-pollinated, the Japanese Ivy is likely to feature stunningly beautiful creamy streaks. The variety prefers well-drained fertile soil with a pH range of 6.0 to 7.5, meaning they prefer neutral or slightly acidic conditions. 7. Russian Ivy (Hedera Pastuchovii) Triclopyr: In rough grass areas, Vitax SBK Brushwood Killer, containing triclopyr, can be used as it should not seriously damage long grass. However, it could affect the developing growing points of bulbs, particularly if applied in late winter, causing foliage and perhaps flower distortion in the season following application. Therefore, if treating areas under-planted with bulbs, avoid run-off into the soil as much as possible.Ivies are natives of Eurasia and North Africa but have been introduced to North America and Australia. They invade disturbed forest areas in North America. [3] Ivy seeds are spread by birds. [3] a b Ingham, C.S.; Borman, M.M. (2010). "English Ivy ( Hedera spp., Araliaceae) Response to Goat Browsing".

The closely related species Hedera canariensis and Hedera hibernica are also often treated as subspecies of H. helix, [12] [14] though they differ in chromosome number and so do not hybridise readily. [11] H. helix can be best distinguished by the shape and colour of its leaf trichomes, usually smaller and slightly more deeply lobed leaves and somewhat less vigorous growth, though identification is often not easy. [12] [15] Range [ edit ] Common ivy clinging on a London plane tree in Agde, France To create a shape with ivy, use a wire frame stuffed with sphagnum moss, which you can find at garden centers. Pin the vines of the ivy to the moss as it grows. Repotting an Ivy Houseplant It isn’t one of the tallest varieties. But still, this plant can stretch up to a whopping 40 feet in height and thrive best in hardiness zones 6 to 9. While Swedish ivy is not a true ivy plant, it remains a popular addition to many gardens and is colloquially included in the category of ivy. Surprisingly, it is not native to Sweden at all but instead is endemic to Australia and the Pacific Islands . The more time you spend with botanical names, the more clear it becomes that colonial, euro-centric efforts shape so much of our world – even the names of plants. Plectranthus Australis is beloved for its long trailing vines and stems, and scalloped edges . Other common names include Swedish begonias and creeping charlie (though it is from the much-begrudged creeping charlie weed in North America).

Regular pruning will maintain ivies in a self-clinging, non-flowering juvenile state. For maximum wildlife value, however, it is best to allow adult growth to develop. Some cultivars are available suspended in particular states – for example ‘Arborescens’ and ‘Ice Cream’ are both adult-only plants, which means they are bushy, non-climbing and flower every year.

Unusually ivies have two distinct stages of growth. They produce soft juvenile foliage when young - which gardeners appreciate. This is followed by woody, adult growth which bears flowers and berries. Leaving a mature ivy to flower will provide a precious source of nectar in late-autumn - followed by late-spring berries. Birds and bees both appreciate this. Does ivy kill trees?

As with any self-climbing facade green, some care is required to make best use of the positive effects: Ivy covering the walls of an old building is a familiar and often attractive sight. It has insulating as well as weather protection benefits, dries the soil and prevents wet walls, but can be problematic if not managed correctly. The genus name Hedera is the Classical Latin word for 'ivy', which is cognate with Greek χανδάνω ( khandánō) 'to get, grasp', both deriving ultimately from Proto-Indo-European * gʰed- 'to seize, grasp, take'. The specific epithet helix derives from Ancient Greek ἕλιξ ( helix), ' helix', and from the Latin helicem, 'spiral', first used around 1600. The binomial in its entirety thus has the meaning "the clinging plant that coils in spirals (helices)". [4] [5] [6] The modern English ivy derives from Middle English ivi, from Old English īfiġ, deriving in turn from Proto-Germanic * ibahs. The meaning is uncertain, but the word may be cognate with the Ancient Greek ἴφυον ( íphuon), referring to not Hedera helix, but the unrelated English lavender, or Lavandula angustifolia.
