Erica verticillata

Erica verticillata

Erica verticillata

Scientific name

This plant is extinct in the wild. It has been re-established to three Sand Plain Fynbos reserves within the urban sprawl of Cape Town. These include Rondevlei Nature Reserve, Kenilworth Racecourse Conservation Area and the Tokai Park under management of the South African National Parks. Its status remains Extinct in the Wild and will be re-assessed when it has survived three burn cycles in the wild without restocking or replanting.

Records suggests this species preferred seasonally damp, acid, sandy soils near rivers and wetlands. Like other ericas it depended upon a symbiotic association with micorrhiza fungi to survive the trials of hot dry summers. Erica verticillata is one of the relatively few reliable South African ericas that is comparatively hardy, disease resistant and recommended for planting in both gardens and containers.

Visited and pollinated by hawk moths, bumblebees, bees, beetles and birds such as southern double-collared sunbirds.

Propagation instructions

By seed

Erica verticillata does not readily produce seed unless two or more different clones are in relatively close proximity for intraspecific cross-pollination to take place.

Seed is sown in late summer or autumn at Kirstenbosch, but best sown at the beginning of the growing season in other areas. It should be sown fresh and be less than three years old unless preserved under optimal seed storage conditions. Seed is sown in seed trays on a well-drained sandy or peat-based potting mixture of equal parts coarse river sand and well-decomposed pine bark or good quality peat. The potting medium should be acidic, contain no manure and have low levels of phosphate with an optimum pH of 5-6.5. The seed is lightly covered with coarse sand, and then subjected to smoke treatment before the trays are watered. This allows for maximum smoke penetration into the medium containing the seed. Smoke is generated in a drum using dry and semi-dry fynbos plant material and is pumped into a sealed plastic tent stretched over a frame containing the trays of seed. The smoke is allowed to settle onto the medium, leaving a brownish film, after which the trays are removed from the tent. The seed trays are lightly watered, taking care not to disturb the seed. The alternative to applying the trays with smoke is to use the Kirstenbosch Smoke Plus Seed Primer which is a disc impregnated with smoke concentrate (Brown et al., 1993). Erica seed germinates approximately three to four weeks after sowing and produces very small cotyledons. The true leaves appear from the eighth to the twelfth week. Seedlings can be pricked out after they have reached 5mm in height into multi-trays or plugs and a well-drained medium to avoid root rot.

By cutting

Erica verticillata is one of the easiest Ericas to propagate vegetatively. It roots best from late summer to autumn (March-May) at Kirstenbosch, elsewhere it is recommended that cuttings are taken in the active growing season. Heel cuttings selected from thin side shoots from the previous season's growth give the best results, but they will also root from tip cuttings. At Kirstenbosch they are rooted in multi-trays in a medium of equal parts 6mm milled pine bark and polystyrene or perlite chips under mist on heated propagation benches. Rooting is enhanced by using a powder-based rooting hormone for semi-hardwood cuttings or by dipping the base of the cutting for five seconds in 2,000 ppm IBA solution. Rooting takes from three to six weeks. Once well rooted, cuttings are removed from the propagation benches and hardened off away from bottom heat and mist. At this stage they should be fed with diluted (50%) liquid, organic, seaweed-based fertilisers.

Managing a collection

The best way to manage the mother stock is to have two key points in mind 1) maintain a high turnover 2) avoid fertilizers/chemicals. All plants kept for mother stock should be pruned and kept bushy so they can be used for propagation.The Erica verticallata is an easy plant to take care of, however, always remember the reason you keep the plant. Taking care of this species for restoration will differ from keeping it for mother stock.

Things to note when growing the Erica verticillata for restoration

1. Understand the site that it will be planted out at & collect the soil from it. Site soil is like "Gold' as it gives off how well the plants will adapt.

2. Restoration is about growing plants as "hardy" as you can. This is because these plants will not have regular maintenance nor watering.

3. Always use polystyrene pots, this is to assure that the plant roots do not absorb any sort of chemical during growth.

Planting out Ericas

1. Ericas grow well in restoration sites that have fully grown ground cover. Rule of thumb is to introduce Ericas last to a restoration site.

2. Always make sure they are planted in areas where they can get enough sunlight & shade(40%) throughout the day.

3. After the plants are planted out do not weed around them, the plants' roots communicate via a fungus that should not be disturbed.
